ABOUT OUR WEBSITE
Instead of the expensively fancy rendering but technically irrelevant website of our competitors, which is essential to cunningly market their asymmetric “me-too” electric motor system provides better performance than another “me-too” asymmetric electric motor system within the same packaging that comprises the universally essential “active stator assembly” but the non-optimal “asymmetry” of a “passive rotor assembly” with rare-earth permanent magnets, such as the Infinitum Electric motor system or H3X Technologies electric motor system, reluctance saliencies, such as the Turntide Technology motor system, DC field windings, such as the BMW iX M60 electric vehicle motor system, or slip-induction dependent windings, such as the ubiquitous induction motor system, BEM’s technically detailed but frugally plain website is essential to indisputably verify that only our reimagined and patented “symmetric synchronous” electric motor system (and SYNCHRO-SYM Technologies), which comprises the optimal “symmetry” of an “active rotor assembly” within the same asymmetric electric motor packaging (less rare-earth permanent magnets), calculates to twice the performance and octuple the peak torque at half the cost and loss (per unit of power rating) as was universally proven during the last century of classic electric motor study by postulating the necessary invention of a stabilizing brushless real time emulation control (BRTEC) means!

PRODUCT → SYNCHRO-SYM Technologies:
SYNCHRO-SYM is the only “Symmetric” Synchronous Electric Motor or Generator Circuit and Control Architecture with the optimal symmetry of an “active rotor assembly” that stably, wirelessly, independently, and synchronously contributes an additional increment of working power (or active power) to the electromechanical energy conversion process along with the universally essential “active stator assembly” that provides the rated torque (and power) of all electric motor systems. SYNCHRO-SYM is only possible with the patented breakthrough invention of automatically precise, Brushless, Sensorless, and Multiphase Real Time Emulation Control (BRTEC) for stable synchronous operation, regardless of speed from sub-synchronous to synchronous and super-synchronous speeds. In complete contrast, all other electric machine systems use the me-too “Asymmetric” Electric Motor or Generator Circuit and Control Architecture with the non-optimal 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 wastes precious electric motor real-estate, power potential, and cost by not independently contributing additional working power to the electromechanical energy conversion process along with the universally essential active stator assembly, which is under today’s estimating control derivative of field-oriented excitation control (FOC). By simply retrofitting any other electric motor or generator system with the brushless, stable, synchronous, and symmetric circuit and control architecture of SYNCHRO-SYM, which uniquely makes the otherwise wasted rotor assembly an additional active power contributor to the electromechanical energy conversion process, a century of classic electric motor and generator study proved that the power density of the original “me-too” asymmetric electric machine “system” package would double, the loss would halve, the cost would halve, and the peak torque would octuple per unit of power rating.
Simply said, whatever improvement in power density, efficiency, or cost per unit of power rating that a me-too asymmetric electric motor manufacturer may flaunt, which is limited to empirically applying a selection of available materials, winding arrangements, electronic components, packaging, thermal management, or manufacturing techniques available to all, then retrofitting the same package (less RE-PMs) with the new “symmetric” circuit and control technology of SYNCHRO-SYM will show double improvement in power density, efficiency, and cost per unit of power rating and also, octuple improvement in peak torque, all by uniquely making the otherwise “passive” rotor assembly an additional “active” contributor to the electromechanical power conversion process along with the active stator assembly.
It follows that only SYNCHRO-SYM comparably performs with available field wound superconductor (or so-called super permanent magnet) electric motor system but without the loss, cost, size, and complexity of cryogenic provisioning and also, only SYNCHRO-SYM uniquely favors the employment of wide bandgap (WBG) power semiconductors by at least doubling their expected performance when applied to any asymmetric electric motor or generator system.
MOTORPRINTER is the only 3D Printer Method for the rapid additive manufacture of low or high frequency, high power, axial-flux electric motor, generator, and transformer cores: 1) with the integral frame and winding assemblies, 2) with the highest performing, ultrathin electrical steel, amorphous metal, or nanocrystalline metal ribbon that has been impractical with conventional electric machine manufacturing due to high tool wear, material damage, or ultrathin material machine dexterity, 3) with perfectly aligned slots and channels of any programmable shape for windings, permanent magnets, reluctance saliencies, or cooling means, 4) with perfectly flat air-gap surfaces without the tool wear and material damage by secondary tooling processes, such as blanchard grinding, 5) with the magnetic flux ideally confined to the solid, low loss, high permeable, non-crystalline core material, 6) with feedstock materials electromagnetically, structurally, and thermally compatible with the product being additively manufactured instead of compatible with the 3D Printer, which is unlike all other 3D Printers, and 7) within a small, remotely controlled, additive manufacturing footprint (e.g., shipping container) instead of the traditional century-old assembly line manufacturing with costly capital equipment inventory, large smokestack facilities, and oppressed offshored labor.
BEM-CAD is 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 enhancing techniques for truly equitable cross-comparative analysis. Interfaced to BEM-CAD, MOTORPRINTER is programmed to additively manufacturer (or 3D Print) axial-flux SYNCHRO-SYMs with the unique BRTEC electromagnetic computer conveniently and compactly 3D Printed within the otherwise wasted annulus space of the 3D Printed low frequency symmetric synchronous doubly-fed electric machine entity for another level of system power density and inventory reduction.
With much global research in the manufacture of the axial-flux electric motor form, only MOTORPRINTER with BEM-CAD will revolutionize and democratize the manufacture of superior performing axial-flux electric motors, generators, and high power, high frequency electromagnetic transformers by providing distributed, field programmable, just-in-time manufacture in a small portable footprint.
BMSCC is the only Brushless Bidirectional Multiphase Self-Commutated Controller with a unique isolated, common mode rejecting, high power, inherent resonant switching, automatically exact symmetric magnetic sharing circuit and control architecture (i.e., high power gyrator) that provides the most versatile Smart Power Converter products with the lowest cost, highest efficiency, highest power density, and lowest distortion possible.
BMSCC is 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 is the only Bidirectional, Multiphase, High Frequency, Electricity Micro-Distribution Bus with a unique isolated, common mode rejecting, high power, inherent resonant switching, automatically exact symmetric magnetic sharing circuit and control architecture (i.e., high power gyrator) that provides the most versatile micro-distribution bus with the highest efficiency and power density at half the cost, half the active electronic stages, and lowest harmonic content in a system of systems (SoS) application, such as electric vehicles, electric airplanes, etc.
BM-HFDFB is essential for lowering the cost, reducing the size, and improving the efficiency of any electric transportation system, such as electric vehicles.
PRODUCT → FOCUS:
A dramatic decline of the traditional internal combustion engine (ICE) vehicle with a mechanically geared powertrain is anticipated with the rapid adoption of the more universally efficient, energy recovery, electric propulsion motor powertrain (e.g., E-mobility), which leaves the electric motor/generator and distribution system as the major consumer of electric vehicle (EV) 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, field maintenance returnable, self-adaptable flying platforms for the broadest, most reliable communication network coverage possible (e.g., 5G), which is impractical with single mission, expendable satellites. Modular, lightweight, high power electric generator systems are being explored to reduce delivery, field installation, and sustainment costs of large offshore wind-turbines. Alone, the electric propulsion motor system market is expected to reach $1.4T by 2028 (BB) with a CAGR of 26.7%.
The gearless or direct-drive electric motor/generator (or electromagnetic) powertrain is the most efficient, reliable, and maintenance-free solution to any mechanically geared powertrain, including geared electric motor systems, and as a result, will be the powertrain of choice, regardless of ICE or Electric Vehicle type!
Ironically, the entire electric motor/generator system industry is approaching this electric transformation with the same century old, “me-too” asymmetric electric motor or generator circuit and control architecture with the non-optimal asymmetry of the universally essential “active” stator assembly but with 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) and associated provisioning, such as brushes, sliprings, RE-PM structural and thermal reinforcements, cryogenics, etc. Unlike the “active stator assembly,” which determines the torque and power rating of the asymmetric electric motor system, the “passive rotor assembly” effectively wastes the other half of precious electric motor and generator system power potential, cost, and real-estate by not independently contributing additional working power to the electromechanical energy conversion process. As a result, the performance marketing distinction between “me-too” asymmetric electric machine systems is limited to: a) hiding the technical details of the electric motor system from the EV specifications to avoid exposing “me-too” similarity, b) enhancing performance by empirically applying available materials, winding, packaging, manufacturing, thermal management, and electronic component performance enhancing techniques that would always result in the same stable maximum load speed (MLS) or constant-torque speed range and associated performance, if equally applied between asymmetric electric motor systems that are designed to the same continuous torque, excitation frequency and voltage, MLS, and air-gap flux density, c) forming alliances with leading innovators to mutually leverage verified empirical packaging techniques, or d) investing in creative cost-reducing manufacturing principles, such as NIDEC’s $1.8 billion investment in high volume electric vehicle motor manufacturing, after recognizing electric vehicle OEMs are cunningly marketing virtually the same performing asymmetric electric propulsion motor system.
Today’s 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 cartel-controlled by a global adversary seeking world dominance with blatant disregard to the environmental and human suffering consequences of producing its RE-PMs?
Demonstrating the global adversary’s insidious control on electric motor innovation and manufacture, today’s best solution to the geopolitical, forced labor, environmental, and expensive consequences of producing RE-PM electric machine systems is restricted to only reducing the amount of deliberately pricier RE-PM materials by ironically mating a higher speed (and therefore smaller) RE-PM electric motor system with an unusually high frequency electronic excitation controller and an extraneous, high-speed gearbox that actually “compounds” the overall complexity, cost, reliability, maintenance, noise, size, and loss of the entire propulsion drivetrain?
Athough 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, so-called yokeless, coreless, or PCB electric motor companies, such as Infinitum Electrics, actually need more RE-PM materials to accommodate their deeper air-gap depth?
Only BEM is introducing a patented synchronous electric motor or generator system, called SYNCHRO-SYM, with the optimal “symmetric” circuit and control architecture that wirelessly, synchronously, and stably combines the working power production of two similarly rated, directly excited (e.g., bidirectional) multiphase winding sets (or “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), cost, and loss while doubling the overall performance with another active winding set. Hypothesized by a century of electric machine study, the symmetric synchronous circuit and control architecture of SYNCHRO-SYM was known to be only possible with the patented breakthrough invention of automatically exact, brushless, sensorless, and multiphase real time emulation control (BRTEC) of the rotor and stator torque and magnetizing fluxes for continuously stable “synchronous” operation from sub-synchronous to super-synchronous speeds, including zero and synchronous speeds, regardless of random rotor or line perturbations. Effectively, BRTEC is the only power conditioning and process control technology with the “digital twin” embedded in the runtime control hardware and software instead of applied as a design tool during engineering, development, and manufacture. 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 and stator, each, consume half of the loss, cost, and size of any electric machine with the compounding effects of friction and electronic control, SYNCHRO-SYM provides at least double the continuous power density at half the cost, half the size (or double power density), half the loss (including windage), and octuple the peak torque per unit of continuous power rating as the “asymmetric” electric motor circuit and control architecture with a single active winding set in the same package of material (less RE-PMs), winding, electronic component, thermal management, and manufacturing techniques.
The patented electric motor circuit and control technology of SYNCHRO-SYM eliminates RE-PMs while providing twice the performance and octuple the peak torque (e.g., gearless EV drive) within the same packaging of size, cost, and loss as the RE-PM electric machine system and also, the patented electric motor 3D Printer Method of MOTORPRINTER democratizes the manufacture of high-performance electric motors, such as SYNCHRO-SYM, with distributed additive manufacturing in a small footprint!
The double performance gain of SYNCHRO-SYM over all other electric machine systems, including the RE-PM electric machine system, has been verified by a simple qualitative proof and by extrapolation from the qualitative analysis by an electric machine expert.
Also, 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, by at least halving the number of active components. 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 electric transformers, 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 inexact electronic excitation control derivative of estimating field-oriented controller (FOC), MAGNAX shows some of the highest performance metrics for the century old, me-too asymmetric electric motor system by empirically applying a custom selection of commonly understood RE-PM YASA packaging enhancing techniques to mitigate manufacturing and thermal management challenges of the asymmetric axial-flux synchronous electric motor system, including the structural, permeability, and flux saturation limits of soft magnetic material.
By simply retrofitting the same asymmetric circuit and control technology of MAGNAX with the patented brushless and symmetric multiphase doubly-fed electric machine circuit and control technology of SYNCHRO-SYM, which keeps the MAGNAX active stator assembly with the same continuous torque, excitation frequency and voltage, and air-gap flux density parameters but instead, replaces the size, loss, and cost of the MAGNAX “passive rotor assembly” and estimating FOC with the symmetry of a working power contributing “active rotor assembly” as only possible with the synchronous stabilization of an automatically exact, brushless, sensorless, and multiphase real time emulation controller (BRTECTM), the power density of the original MAGNAX electric machine system package would comparably double again per unit of power rating (for twice the publicized 5x power density of MAGNAX), the cost would comparably halve per unit of power rating, the efficiency would comparably increase per unit of power rating, and the peak torque would comparably octuple per unit of power rating, all by effectively eliminating the compounding cost, loss, and size effects of the passive rotor assembly of RE-PMs with serious geopolitical, limited operational life expectancy, wasteful cogging drag, unfriendly environmental, and unsafe handling consequences and by replacing the full rated FOC with a half rated BRTEC.
The simple retrofit comparison between SYNCHRO-SYM and the original MAGNAX conveniently shows:
- Like MAGNAX, SYNCHRO-SYM follows the same material, winding, packaging, and electronic component enhancing techniques and as a result, is straight-forward ready,
- Like MAGNAX, SYNCHRO-SYM follows the same operation, design, construction, and manufacture and as a result, is straight-forward ready,
- Like MAGNAX, SYNCHRO-SYM uses off-the-shelf components (but without RE-PMs) and as a result, is straight-forward ready,
- 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,
- 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,
- 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) universal single AC, multiphase AC, or DC operation, ii) coveted field weakening for extended speed range, electronic control reliability, and highest efficiency at any speed, iii) efficient cog-less motoring and generating (i.e.,, no RE-PMs), iv) direct and independent phase and amplitude control of the rotor and stator torque and magnetizing MMF (and resulting fluxes) at runtime to exactly satisfy synchronous operation at any speed, to balance the neutral node in a 3 wire, three-phase system (e.g., common mode rejection) for instance, etc., v) “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 cost per unit of power rating, vii) the reliability and resiliency of BRTEC with inherent resonant switching, viv) the direct AC-to-AC power conversion of instantaneous, sensorless, 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, and vv) best utilization of the axial-flux form factor by conveniently placing the compact HF electromagnetic computer of BRTEC within the otherwise wasted annulus of the electric motor axial flux core, when under the design of BEM-CAD and the manufacture by MOTORPRINTER, for another level of system power density and component inventory reduction with physically the same rotor and stator assemblies (less software programming).
While solving the manufacturing production, the thermal management challenges, and eliminating the structural, permeability, and flux saturation limits of soft magnetic material of axial flux electric motors and with the unique ability of forming perfectly aligned slots and channels of any programmable shape in solid nanocrystalline or amorphous ribbon materials for windings, permanent magnets, reluctance saliencies, or thermal management, the patented MOTORPRINTER revolutionizes and democratizes the manufacture of axial-flux low and high frequency electric motors, generators, and transformers, such as found in SYNCHRO-SYM, with a rapid, just-in-time, compact, scalable, low waste, non-smokestack, remotely controlled, self-contained 3D Printing method that uniquely layers off-the-shelf performance enhancing materials without material property damage or tool wear, such as high performance amorphous or nanocrystalline metal ribbon, structural material, and magnet wire, which are optimally premanufactured to be electromagnetically, structurally, and thermally compatible with the resulting electric motor product, instead of traditional 3D Printers that universally layer specialized materials that are optimally premanufactured to be compatible with the 3D Printer, such as powders, filaments, etc., instead of the product being manufactured.
The patented circuit and control architecture of the automatically exact, Brushless, Sensorless, and Multiphase Real Time Emulation Controller (BRTEC) with electromagnetic processing and inherent resonant switching provides several patented hybrid configurations. For instance, the patented 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 (power switches) for higher efficiency, lower cost and lower size. The patented 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.
PRODUCT → DEVELOPMENT:
The Koenigsegg Quark E-Motor is another electric motor system that publicly claims best overall performance from all other “me-too” (or asymmetric) RE-PM motor systems by the application of Koenigsegg’s empirical selection of available packaging enhancing techniques. With the same packaging techniques, BEM-CAD results show that retrofitting the Koenigsegg Quark E-Motor with the new symmetric circuit and control architecture of SYNCHRO-SYM twice magnifies the performance. Without exotic materials, such as Halbach arranged permanent magnets, or manufacturing techniques, SYNCHRO-SYM, which always includes the integral BRTEC for full rated electronic control, shows power density up to 58 KW/L versus Koenigsegg’s 31.3 KW/L and specific power up to 14.4 KW/Kg (versus Koenigsegg’s 8.7 KW/Kg). Likewise, H3X Technologies is struggling to reach these numbers as well.
Future BEM products that are best enabled by SYNCHRO-SYM Technologies, such as a ubiquitous but sightless green hydrogen capture method, a modular and programmable (SW) electric vehicle propulsion drivetrain method, an energy managed reciprocity method, etc.
