SYNCHRO-SYM TECHNOLOGIES


PRODUCT → SHAPING OUR ENERGY FUTURE:

In accordance with Our Mission to “Innovate For Our Clean, Efficient, and Sustainable Energy Future,” Best Electric Machine (BEM) offers a portfolio of patented, straight-forward-ready technologies, branded SYNCHRO-SYM Technologies, that exclusively approach the theoretical limit in performance/price for reimagining: a) smart electric motor and generator systems, such as for electric transportation, b) smart 3D printing method of high performance axial-flux electric motors, generators, and transformers, c) smart electric power conditioning and transfer, such as wireless power transfer, and d) smart electric polyphase micro-distribution, which will significantly magnify the expected gain from applying performance enhancing technologies, such as emerging wideband gap (WBG) power semiconductor switches, and will ethically mitigate today’s stifling dependency on rare-earth materials that are insidiously controlled by a global adversary seeking world dominance with harmful exploited labor, human rights, environmental, innovation, and geopolitical consequences.


PRODUCT → OFFERINGS:

SYNCHRO-SYM reimagined the electric motor and generator (i.e., electric machine) system with the only “Symmetric” Synchronous Electric Motor or Generator Circuit and Control Architecture comprising the optimal electromagnetic symmetry of an “active rotor assembly” that independently contributes an additional increment of working power (or active power) to the electromechanical energy conversion process along with the universally essential power and torque producing “active stator assembly” found in all electric motor systems, which is only possible with the breakthrough invention of automatically precise, Brushless, Sensor-less, Multiphase Real Time Emulation Control (BRTEC) for enabling contiguously stable “synchronous” operation from sub-synchronous to super-synchronous speed, including at or about synchronous and zero speeds, by its built-in runtime digital twin.

All other electric machine systems implement the me-too “Asymmetric” Electric Motor or Generator Circuit and Control Architecture with the non-optimal electromagnetic asymmetry of a “passive rotor assembly” of either slip-induction dependent windings, reluctance saliencies, rare-earth permanent magnets (RE-PM), or DC field windings that effectively wastes half of the total electric motor real-estate, loss, and cost by not independently contributing additional working (or active) power to the electromechanical energy conversion process along with its active stator assembly, which is always controlled by an estimating derivative of off-line, field-oriented control (FOC), such as direct-torque control (DTC), for contiguously stable operation to only synchronous speed.

By simply retrofitting the “passive rotor assembly” of the “me-too” or asymmetric circuit and control architecture of any other electric motor or generator system with the “active rotor assembly” of the only symmetric circuit and control architecture of SYNCHRO-SYM, a century of classic electric motor and generator study, research, and publication and a regimen of BEM prototyping and invention have verified the power density of the original retrofitted asymmetric electric machine “system” package would double, the loss would halve, the cost would halve, and the peak torque would octuple (per unit of continuous power rating).


Our Distinctive Value Proposition: SYNCHRO-SYM is the only electric motor system with an “active rotor” that stably contributes an additional increment of power to the electromechanical energy conversion process along with the active stator. All other electric motor systems, including so-called “breakthrough airplane propulsion electric motor systems,” have a “passive rotor” of rare-earth permanent magnets, reluctance saliencies, conventional or superconductor field windings, or slip-induction windings that effectively wastes half of the motor real-estate, loss, and cost without stably and independently contributing additional “working power” to the electromechanical energy conversion process!!

Today: Only SYNCHRO-SYM “Total System” Power Density reaches over 66 KW/L, Specific Power reaches over 16 KW/Kg, Efficiency reaches over 96%, and Cost is halved per unit of power rating with the same design specification (e.g., 800 volts DC, 4000 RPM, and 1.25T flux density), with the same electric machine package and performance enhancing techniques, with the compounding size, loss, and cost of the electronic controller “extraordinarily” included, and without precious rare-earth permanent magnets or superconductor electromagnets!

Tomorrow: Only SYNCHRO-SYM will continue to effectively double the advertised performance gain with half the cost and amount of material, such as copper, per unit of power rating of any present or future electric machine packaging and performance enhancing techniques available to all electric machine systems, such as the performance and cost of emerging wide-bandgap semiconductor (WBG) switches, by “uniquely” enabling the rotor to be an additional “working power” contributor to the electromechanical energy conversion process along with the universally essential active stator for primary torque and working-power production! When superconductors become a practical reality, the fully electromagnetic SYNCHRO-SYM will be the only electric motor system of choice!


MOTORPRINTER reimagined electric motor manufacture with the only 3D Printer Method for the low cost, rapid, just-in-time, additive manufacture of low or high frequency, high power, axial-flux electric motor, generator, and transformer cores: 1) with programmable slot and channel shapes for the tight placement of RE-PMs, windings, rotor saliencies, or cooling channels, 2) with perfectly flat air-gap surfaces, 3) with integral frame and winding assemblies, 4) with off-the-shelf, highly optimized feedstock layering materials that are electromagnetically, structurally, and thermally compatible with the electric machine product being additively manufactured, such as highest performing, ultrathin electrical steel, amorphous metal, or nanocrystalline metal ribbons, structural material, and magnet wire, instead of being compatible with the 3D Printer itself, such as the typical 3D Printer feedstock powders, filaments, etc., 5) within a compact self-contained, remotely monitored and controlled footprint (e.g., shipping container) instead of the traditional century-old assembly line manufacturing with costly capital equipment inventory, large industrial power consuming smokestack facilities, and exploited offshored labor, and 6) with production scaling by simply adding or stacking another household powered, compact self-contained MOTORPRINTER footprint.

BEM-CAD reimagined electric motor design with the only computer-aided-design (CAD) tool that simultaneously designs axial-flux SYNCHRO-SYMs, RE-PM electric machine systems, and Induction electric machine systems to the same continuous torque, air-gap flux density, maximum load speed (MLS), frequency of excitation, and port voltage design and with the same material, winding, thermal management, electronic component, and packaging performance enhancing techniques for truly equitable cross-comparative analysis. Interfaced to BEM-CAD, MOTORPRINTER is programmed to additively manufacture (or 3D Print) axial-flux SYNCHRO-SYMs of virtually any power rating with duplicate rotor and stator assemblies by conveniently 3D Printing its unique BRTEC electromagnetic computer within the otherwise wasted annulus space of the low frequency symmetric synchronous doubly-fed axial-flux electric machine entity, all of which provide another level of system power density and component inventory reduction.

Complemented with its superior performance, simpler electronic power condition, and the straight-forward additive manufacture of MOTORPRINTER (under the design control of BEM-CAD), only the optimum electromagnetic symmetry of SYNCHRO-SYM inherently facilitates: a) a unique high capacity thermal management system that provides continuous operation at ultrahigh power densities and the designed-in convenience of incrementally stacking a multiplicity of SYNCHRO-SYM E-Motors lengthwise (i.e., power stacking) to provide incrementally higher power rating and fault tolerant redundancy (within smaller effective diameter and without affecting power density or specific power).


Only MOTORPRINTER under the programmable control of BEM-CAD will revolutionize and democratize the manufacture of superior performing low and high frequency, axial-flux electric motors, generators, and transformers with seamlessly scaled, inhouse or distributed, field programmable, just-in-time additive manufacturing and as a result, will neutralize the unethical advantage of offshoring for exploited labor manufacturing.


BMSCC reimagined bi-directional electronic power conditioning with the only Brushless Bidirectional Multiphase Self-Commutated Controller that provides a unique, compact, high power, isolated, common mode rejecting, fault tolerant, high frequency zero-crossing fault detection and fusing, inherent resonant switching, automatically exact, electromagnetically symmetrical magnetic sharing circuit and control architecture (i.e., high power gyrator) that provides the most versatile Smart Power Converter products with automatic frequency translation, direct AC(1ph,2ph,…)/DC-to-AC(1ph,2ph,…)/DC conversion, and wireless power transfer with the lowest cost, highest efficiency, highest power density, and lowest distortion possible.


BMSCC is unbeatably essential for implementing synchronous or asynchronous grid forming (GFM), inverter based resources (IBR), such as Bidirectional Multiphase Inductive (Wireless) Power and frequency Transfer Systems (M-IPTS), fast electric vehicle chargers, static synchronous compensators (STATCOM) for enabling the flexible AC transmission system (FACTS), compact high power phase shifting transformer, etc.


BM-HFMDB reimagined electric power micro-distribution with the only Bidirectional, Multiphase, High Frequency, Electricity Micro-Distribution Bus that provides a unique, isolated, common mode rejecting, high power, fault tolerant, high frequency zero-crossing fault detection and fusing, inherent resonant switching, automatically exact, electromagnetically symmetrical magnetic sharing circuit and control architecture (i.e., high power gyrator) that halves the cost, halves the number of active electronic stages, halves the loss, halves the harmonic content, and halves the complexity of the entire system of systems (SoS) application, such as electric vehicles, electric airplanes, wind turbine farms, etc.


BM-HFDFB is unbeatably essential for lowering the cost, reducing the size, and improving the efficiency of any electric transportation SoS, such as electric vehicles.


PRODUCT → FOCUS:

A dramatic decline of the traditional mechanically geared powertrain vehicle, which is typically driven by an internal combustion engine (ICE), is anticipated with the rapid adoption of the more universally efficient, reliable, low maintenance, energy recovery (e.g., regeneration) electric propulsion motor powertrain (e.g., E-mobility) for any type of vehicle, such as battery, fossil or hydrogen fuel cell, or fossil or hydrogen ICE powered vehicles, which leaves the electric motor/generator (and micro-distribution) system as a major consumer of the vehicle’s loss, cost, and size. Efficient, high power density electric propulsion is needed for environmentally friendly short distance passenger airplanes or for autonomous unmanned, long duration, high altitude, solar powered (e.g., no fuel for launch, landing, or sustainment), maintenance returnable, self-adaptable flying platforms, such as for the broadest, low delay, most reliable communication network coverage possible (e.g., 5G) that is impractical with traditional or clustered, and expendable satellites with associated infrastructure provisioning. Modular, lightweight, high power electric generator systems are being explored to reduce delivery, field installation, and sustainment costs of large wind-turbines.  As the backbone of the entire electricity infrastructure, electric machine system innovation provides enormous opportunities: a) for the efficiency, cost, power density, and future of our commercial or industrial energy infrastructure, b) for net zero carbon emission, and c) for combating global warming. Without considering commercial and industrial applications, the electric propulsion motor system market, alone, is expected to reach $100B by 2030 (BB) with a CAGR of 26.6%.

Ironically, the entire electric motor/generator system industry is approaching this electricity infrastructure transformation with the same century old, me-too or “asymmetric” electric motor or generator circuit and control architecture with the non-optimal asymmetry of the universally essential “active” stator assembly comprising a directly excited (e.g., bidirectional) multiphase winding set (or active winding set) for torque and power production but a “passive” rotor assembly comprising either rare-earth permanent magnets (RE-PM), slip-induction dependent windings, reluctance saliencies, or DC field windings (e.g., conventional or superconductor electromagnets) with associated provisioning, such as brushes, sliprings, RE-PM structural and thermal reinforcements, cryogenics, etc., and an offline, estimating FOC or DTC controller derivative for contiguously stable operation to synchronous speed or the maximum load speed (MLS). Unlike the “active stator assembly,” which always determines the overall torque rating of the asymmetric electric motor system by independently contributing working power to the electromechanical energy conversion process, the “passive rotor assembly” effectively wastes the other half of the total electric motor and generator system loss, cost, and real-estate by not independently contributing any working power to the electromechanical energy conversion process along with the “active stator assembly.” In consideration, today’s performance marketing distinction between “me-too” asymmetric electric machine systems from different manufacturers is always: a) hiding the pertinent technical details of the electric motor system from the electric vehicle (EV) specifications to avoid exposing “me-too” similarity, b) enhancing performance by empirically applying a different selection of available materials, winding, packaging, manufacturing, thermal management, electronic component, and design techniques, such as the axial-flux formfactor, that would always result in the same stable constant-torque speed range to synchronous speed (or maximum load speed (MLS)) and associated performance, if equally applied between asymmetric electric motor systems with the same continuous torque, excitation frequency, synchronous speed, and voltage, and air-gap flux density specifications, c) forming alliances with leading innovators to mutually leverage verified performance enhancing techniques, or d) investing in creative cost-reducing manufacturing after recognizing electric vehicle OEMs are cunningly marketing virtually the same performing, century-old, asymmetric electric propulsion motor system, such as NIDEC’s $billion investment in high volume electric vehicle motor manufacturing with a global adversary seeking world dominance.


Today’s anecdotally best solution for mitigating the environmental consequences of “consuming fossil fuels” is to rapidly adopt the “me-too” RE-PM electric motor system, which ironically, is monopolized by a global adversary seeking world dominance with unethical disregard to the harmful geopolitical, exploited labor, human rights, environmental, electric machine system innovation, and pricing consequences, including significant price increases as expected from past experience when future RE-PM shortages occur?

Demonstrating the global adversary’s insidious control on electric motor innovation and manufacture, today’s best solution to the harmful geopolitical, exploited labor, human rights, environmental, innovation, and pricing consequences of producing RE-PM electric machine systems is limited to only reducing the amount of deliberately pricier RE-PM materials by mating a high speed (and therefore smaller) RE-PM electric motor system with an unusual, high frequency electronic excitation controller and an extraneous, speed-reduction gearbox to match the high speed of the motor to the speed of the load, which ironically “compounds” the overall complexity, cost, reliability, maintenance, noise, size, and loss of the entire propulsion drivetrain! Similarly, moving to prevalent but very low energy product ferrite permanent magnets only exasperates this problem by requiring even higher operating speeds and larger gearboxes for the same power density but lower efficiency and reliability as the RE-PM or Induction electric motor systems!

Although the common understanding amongst electric motor manufacturers is directed towards reducing the dependency on precious, costly, environmentally destructive, and geopolitically sensitive rare-earth permanent magnet (RE-PM) materials by higher speed operation, manufacturers of so-called yokeless, coreless, air core, or printed circuit board electric motor systems with lengthy airgaps, such as Infinitum Electrics, are ironically increasing the amount of RE-PM materials per unit of power rating, which can only be artificially sustained by the RE-PM cartel of the global adversary?


Only BEM is introducing a patented “synchronous” electric motor or generator system, called SYNCHRO-SYM, with the optimalsymmetric” circuit and control architecture that brushlessly, synchronously, and stably combines the working power production of two similarly rated “active” winding sets that are symmetrically placed on the rotor and stator, respectively, to inherently maintain the same electric motor package footprint of material (less RE-PMs), construction, cost, and loss while simultaneously doubling the continuous power with octuple the peak torque. Proven by at least a half century of basic electric machine study, research, and publication that were reimagined to practical reality by a regimen of BEM prototyping and invention, the symmetric multiphase wound-rotor “synchronous” doubly-fed circuit and control architecture of SYNCHRO-SYM is known to be only possible with the breakthrough invention of automatically exact, brushless, sensor-less, and multiphase real time emulation control (BRTEC) for guaranteeing contiguously stable operation, regardless of random rotor or line destabilizing perturbations, from sub-synchronous to super-synchronous speeds, including at or about zero and synchronous speeds. Effectively, the patented BRTEC is the only control technology with the “digital twin” embedded in the runtime control hardware and software (i.e., real time emulation) instead of applied as a onetime design tool for research and development. Therefore, under the same MLS design for a given continuous torque, frequency and voltage of excitation, and air-gap flux density, all while reasonably assuming the rotor or stator consumes half of the loss, cost, and size of any electric machine system with the associated compounding effects of friction, induced harmonics, electronic control, and extraneous enabling components for consistently maintaining the rotating air-gap flux density, SYNCHRO-SYM is a drop-in replacement to the asymmetric electric machine system of all others but provides at least double the continuous power with virtually unlimited peak torque density at half the size (e.g., twice the continuous power density), half the amount of material, such as copper, half the cost, and half the loss (per unit of continuous power rating), particularly in an axial-flux format with similar adjacent rotor and stator disks assemblies, by the combined performance of two active winding sets (i.e., doubly-fed) in the same package of material (less RE-PMs), winding, electronic component, thermal management, and manufacturing techniques of any “asymmetric” electric motor circuit and control architecture with only a single active winding set (i.e., singly-fed).


Our flagship product, SYNCHRO-SYM, as only possible with the practical invention of brushless, real-time, emulation control (BRTEC), provides at least six uniquely superior attributes:

  1. The only electric motor or generator system with an “active rotor” assembly that is without passive RE-PMs but instead, stably contributes another increment of “active power” to the electromechanical energy conversion process while reasonably consuming the other half of the total electric motor system package loss, cost, and size along with the universally essential power producing active stator assembly. For example, RE-PMs do not have an electrical port for directly providing multiphase (active) electrical power to the electromechanical energy conversion process and like slip-induction windings, reluctance saliencies, or DC field windings, a rotor of RE-PMs is a “passive rotor.”
  2. The only electric motor or generator system that doubles the power density at half the cost, half the amount of material, such as copper, and half the loss per unit of power rating of the typical electric machine footprint or packaging techniques with the size, loss, and cost of the integrally embedded BRTEC extraordinarily included in the calculations. For example, only SYNCHRO-SYM delivers twice the continuous constant-torque speed range with the same air-gap flux density, torque, voltage, synchronous speed, and excitation frequency design and packaging (less RE-PMs), such as 7200 RPM @ 60Hz for SYNCHRO-SYM with one pole-pair versus 3600 RPM for the asymmetric electric machine system, which is tantamount to twice the continuous power density at half the amount of material, such as copper, half the cost, and half the loss per unit of power rating of asymmetric electric machine systems.
  3. The only electric motor or generator system that provides octuple the typical peak torque at the same maximum load speed, voltage, frequency of excitation, and air-gap flux density by eliminating core saturation with increasing torque current, which is essential for direct drive or gearless electric motor propulsion systems.
  4. The only electric motor or generator system with electric machine circuit and electronic controller symbiosis, which inherently doubles the expected wide bandgap semiconductor performance gain while halving the expected cost per unit of power rating.
  5. The only electric motor or generator system that doubles the expected performance gain while halving the cost per unit of power rating from applying the same performance enhancing techniques to any other electric machine system, such materials, winding, thermal management, packaging, and electronic component techniques, including emerging wide-bandgap (WBG) semiconductors.
  6. The only electric motor or generator system that provides a practical, ethical, and superior but lower cost alternative to the cartel-controlled RE-PM electric motor system, which is anecdotally considered the best performing electric motor system but is cartel-controlled and therefore monopolized by a global adversary seeking world dominance with harmful exploited labor, human rights, environmental, and geopolitical consequences.

Only BEM is introducing a portfolio of patented enabling technologies, branded SYNCHRO-SYM Technologies, that reduces overall size, improves overall efficiency, and lowers overall cost of an electrical System of Systems (SoS) application, such as wind turbine farms and electrically propelled ships, airplanes, and land vehicles. SYNCHRO-SYM Technologies include: a) a patented (and only) electric machine 3D Printing technology, called MOTORPRINTER, for revolutionizing and democratizing the rapid just-in-time additive manufacture of superior performing axial-flux low frequency electric motor and generator systems, such as SYNCHRO-SYM, and high frequency, high power electronic transformers, such as BRTEC, which are essential for lowering the cost, size and loss of the smart electricity infrastructure, b) a patented (and only) Brushless Bidirectional Multiphase Self-Commutated Controller, which is essential for successfully implementing the smart electricity infrastructure, and c) a patented (and only) Bidirectional, Balanced Multiphase, High Frequency, Electricity Micro-Distribution Bus, which is essential for lowering the cost and improving the efficiency of the electric vehicle SoS.


PRODUCT → SHOW ME:

Comprising the asymmetry of a “passive rotor assembly” of rare-earth permanent magnets (RE-PM) and a state-of-art but offline, estimating control derivative of FOC, MAGNAX shows some of the highest performance metrics for the century old, me-too asymmetric electric motor system by empirically applying an engineered selection of commonly understood RE-PM yokeless and segmented armature (YASA) performance enhancing techniques to leverage its advantages while mitigating the manufacturing and thermal management challenges of the dual-airgap axial-flux (i.e., adjacent stator and dual rotor disks) asymmetric synchronous electric motor system with the compounding structural, permeability, and flux saturation constraints of YASA’s soft magnetic material.

By simply retrofitting the same asymmetric circuit and control technology of MAGNAX with the patented brushless and symmetric multiphase wound-rotor synchronous doubly-fed electric machine circuit and control technology of SYNCHRO-SYM, which keeps the loss, cost, and size of the original MAGNAX active stator assembly with the same continuous torque, frequency & voltage excitation, and air-gap flux density ratings but replaces the size, loss, and cost of the MAGNAX “passive rotor assembly” (i.e., dual air-gap disks) and offline estimating control derivative of FOC with the optimal symmetry of a working power contributing “active rotor assembly,” as only possible with contiguous synchronous stabilization by an automatically exact, brushless, sensor-less, and multiphase real time emulation controller (BRTECTM), the power density of the original MAGNAX electric machine system package would comparably double per unit of continuous power rating (i.e., twice the constant-torque speed range), the cost would comparably halve, the efficiency would comparably double, and the peak torque would comparably octuple, as was proven by at least a half-century of electric motor study, research, and publication that were reimagined to practical reality by a regimen of BEM prototyping and invention. Also, the non-optimal asymmetry of RE-PMs with known safety, handling, limited operational life expectancy, wasteful cogging drag, unfriendly environmental, exploited labor, human rights, and geopolitical consequences would be ethically eliminated with the optimal electromagnetic symmetry of another active winding set.

This simple retrofit comparison between SYNCHRO-SYM and the original MAGNAX (or any other electric motor system) conveniently shows:

  1. Like MAGNAX, SYNCHRO-SYM follows the same material, winding, packaging, and electronic component enhancing techniques and as a result, is straight-forward ready,
  2. Like MAGNAX, SYNCHRO-SYM follows the same operation, design, construction, and manufacture and as a result, is straight-forward ready,
  3. Like MAGNAX, SYNCHRO-SYM uses off-the-shelf components (but without RE-PMs) and as a result, is straight-forward ready,
  4. Like MAGNAX, SYNCHRO-SYM is adaptable to legacy or future electric machine systems with customary engineering and manufacturing and as a result, is straight-forward ready,
  5. Like MAGNAX, SYNCHRO-SYM easily leverages third party legacy or future electric machine design, packaging, material, winding, or construction enhancing techniques but with double the expected performance gain and as a result, is straight-forward ready,
  6. But unlike MAGNAX, only the symmetric circuit and control architecture of SYNCHRO-SYM with two similarly rated active winding sets advantageously placed on the rotor and stator, respectively, inherently provides: i) the same packaging footprint and materials (less RE-PMs), ii) universal single AC, multiphase AC, or DC operation, iii) coveted field weakening for extended speed range, electronic control reliability, and highest efficiency at any speed, iv) efficient clogless motoring and generating (i.e., no RE-PMs), v) inherently indestructible without the fragility and limited life expectancy of RE-PM but with the precision control of BRTEC and the proprietary thermal management as only provided by the just-in-time, additive manufacture of MOTORPRINTER, vi) “comprehensive” leading, lagging, or unity power factor compensation over the entire speed range, vii) “comprehensive” regeneration over the entire speed range, viii) best utilization of emerging wide bandgap electronic semiconductor switches with a circuit and control technology that doubles their expected performance with half their expected amount of material, such as copper, & cost per unit of power rating, ix) the reliability and resiliency of BRTEC with inherent resonant switching, x) the direct AC-to-AC power conversion of instantaneous, sensorless, multiphase, and automatic electromagnetic computing (i.e., BRTEC) with inherent active filtering, which eliminates the DC Link Stage of FOC with banks of large, expensive, inefficient, and delicate low frequency, high power capacitors, xi) the unique power conditioning method of BRTEC inherently provides pure sinusoidal excitation, which minimizes electrical stress on electronic components, insulation, etc., xii) best utilization of the axial-flux form factor by conveniently and proportionally placing the compact electromagnetic computer of BRTEC within the otherwise wasted annulus of the electric motor axial flux core, which physically provides the same rotor and stator assemblies (less software programming), and xiii) a simple and highly effective demand based cooling method for another level of system power density and component inventory reduction, all of which are inherent to SYNCHRO-SYM under the additive manufacturing of MOTORPRINTER and the design control of BEM-CAD.
  7. But unlike MAGNAX, the modularized, axial-flux SYNCHRO-SYM is: i) with the same rotor and stator disks with the exception of software configuration (as only provided by the symmetric circuit and control architecture and the additive manufacture of MOTORPRINTER under BEM-CAD), ii) is without the safety and handling issues of RE-PMs, iii) is without the componentized assembly logistics of the typical remotely mounted electronic controller, such as FOC, and iv) as a result, can be conveniently field assembled or field stackable lengthwise for incrementally higher power rating or smaller diameter, direct drive applications.

While solving the challenges of manufacturing production and thermal management of the axial-flux or YASA electric motor system with the structural, permeability, and flux saturation limits of soft magnetic composites, MOTORPRINTER revolutionizes and democratizes the manufacture of low and high frequency axial-flux electric motors, generators, and transformers, such as SYNCHRO-SYM, with a rapid, just-in-time, compact, incrementally scalable, low waste, non-smokestack, remotely controlled, deployable, self-contained 3D Printing method that also exclusively provides a high capacity electric motor system thermal management system. Also, the circuit and control architecture of the automatically precise, Brushless, Sensor-less, and Multiphase Real Time Emulation Controller (BRTEC) with electromagnetic processing and inherent resonant switching provides several patented hybrid configurations. For instance, BM-HFMDB provides the power distribution to multiple SYNCHRO-SYMs in a system of system, such as electric vehicles, with half the number of active devices (i.e., power switches), fault tolerance, and high frequency zero-crossing fault detection and conduction breaking for higher efficiency, lower cost and lower size and BMSCC allows compact and efficient solid-state power conditioning, gyration, and translation from any power, such as DC, single, and multiphase AC, to any voltage, frequency, or phase, such as an EV battery controller and an EV charger.

Already proven by over a half century of independent electric motor study, research, and publication and then, verified by BEM’s prototyping and computer aided design tool (BEM-CAD), BEM hopes the reader takes the necessary time to understand the SYNCHRO-SYM’s concept of operation. It will become evident that any electricity infrastructure product can benefit from applying SYNCHRO-SYM Technologies.   


PRODUCT → SYNCHRO-SYM E-MOTOR:

BEM’s E-mobility market study verified the advertised Koenigsegg Quark E-Motor claims of best overall performance of any other “me-too” (or asymmetric) propulsion motor system with the typical componentized remote electronic controller, because of Koenigsegg unusual data revelation for proper analysis, and as a result, the Quark E-Motor will be the initial competitive market focus of the SYNCHRO-SYM E-Motor. But without exotic materials, such as RE-PMs or superconductors, or packaging techniques, such as Halbach arranged RE-PMs, the SYNCHRO-SYM E-Motor shows “total system” Power Density of 66 KW/L (versus Koenigsegg’s 31.3 KW/L), Specific Power of 16 KW/Kg (versus Koenigsegg’s 8.7 KW/Kg), and total System Efficiency of 96% (versus Koenigsegg’s N.A.%) at 800 volts, 4000 RPM and 1.25T, all while uniquely including the compounding loss, cost, and size of the integrally embedded BRTEC, which demonstrates SYNCHRO-SYM’s double expected performance gain as proven by at least a half-century of electric motor study, research, and publication that were reimagined to practical reality by a regimen of BEM prototyping and invention. With ample funding, other “me-too” asymmetric RE-PM electric motor systems (for electric airplane propulsion), such as MagniX, H3X Technologies Motor, and MIT’s Megawatt Motor, are also struggling to reach the power density, specific power, and efficiency ratings of the Quark-E motor or Koenigsegg newest E-Motor introduction, called Dark Matter. Also, with its superior performance and the inherent facilities provided by the straight-forward additive manufacture with MOTORPRINTER (under the design control of BEM-CAD), the SYNCHRO-SYM E-Motor product offers higher reliability and much lower cost.
