PRODUCT → OFFERINGS:
SYNCHRO-SYM re-imagined the electric motor and generator (i.e., electric machine) system (EMS) with the only “Symmetric” Synchronous Electric Motor or Generator Circuit and Control Architecture (S-EMS) comprising the optimal electromagnetic symmetry of an “active rotor assembly” that stably, independently, and brushlessly contributes additional working power (or active power) and torque 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 speeds, including at or about synchronous and zero speeds.
All other electric motor systems implement the same-old “Asymmetric” Electric Motor or Generator Circuit and Control Architecture (A-EMS) with the non-optimal electromagnetic asymmetry of a “passive rotor assembly” comprising either slip-induction dependent windings, reluctance saliencies, permanent magnet, as only practical with rare-earth permanent magnets (RE-PM), or DC field windings (conventional or superconductor) that effectively wastes half of the total electric motor real-estate, loss, and cost by not stably or independently contributing any working (or active) power to the electromechanical energy conversion process along with its active stator assembly, which is always controlled by an offline estimating control derivative for contiguously stable operation to only synchronous speed, such as field-oriented control (FOC) or direct-torque control (DTC).
By simply retrofitting the “passive rotor assembly” of the “same-old” A-EMS with the “active rotor assembly” of the S-EMS, as only possible by SYNCHRO-SYM, a century of classic theoretical electric motor and generator study, research, and publication, which was only successfully completed by BEM’s persistent R+D, invention, modeling, prototyping, CAD, and patents, have verified: a) the power density of the original retrofitted asymmetric electric machine “system” package would at least double, b) the loss would at least halve, c) the cost would at least halve, and d) the peak torque would at least octuple (per unit of power rating) within the same packaging (less RE-PMs and without considering the additional performance enabling as only possible with the 3D Printing method of MOTORPRINTER)!!
MOTORPRINTER re-imagined electric motor and solid-state transformer 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) re-programmable shape, 2) with integral frame and winding assemblies, 3) 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., 4) 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 5) with production scaling by simply adding or stacking another household powered, compact self-contained MOTORPRINTER footprint.
BEM-CAD re-imagined 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 design specifications, such as continuous torque, air-gap flux density, constant-torque-speed-range (CTSR), frequency of excitation, and port voltage and to the same packaging performance enhancing techniques, such as material, winding, thermal management, and electronic components, 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 designing 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 circuit and control 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).
BMSCC re-imagined 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.
BM-HFMDB re-imagined 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.
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 internal combustion engine powered or battery, fossil, or hydrogen fuel cell powered vehicles, which leaves the electric motor/generator system (EMS) 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 or near space, 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 expendable traditional or clustered 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, EMS 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 vehicle propulsion EMS market, alone, is expected to reach $100B by 2030 (BB) with a CAGR of 26.6%.
Ironically, the entire EMS industry is approaching this electricity infrastructure transformation with the same century old “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) 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) for closing the magnetic circuit 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 constant-torque-speed-range (CTSR). Unlike the “active stator assembly,” which universally determines the overall torque rating of the asymmetric electric motor system by stably and 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 stably or independently contributing any working power to the electromechanical energy conversion process. In consideration, today’s performance marketing distinction between the “same-old” asymmetric EMS (A-EMS) from different manufacturers is always: a) hiding the pertinent technical details of the A-EMS from the electric vehicle (EV) specifications to avoid exposing “same-old” similarity, b) enhancing performance by empirically applying a different selection of available materials, winding, packaging style, such as the axial-flux formfactor, manufacturing, thermal management, electronic component, and gearbox techniques that would always result in the same stable constant-torque-speed-range 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 A-EMS, such as NIDEC’s $billion investment in high volume electric vehicle motor manufacturing with a global adversary seeking world dominance.
Only BEM is introducing a patented “symmetric” electric motor or generator system (S-EMS), called SYNCHRO-SYM, with the optimal “symmetric” 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 as any other (i.e., asymmetric) electric motor system, while simultaneously doubling the continuous power with octuple the peak torque of any other. Proven by at least a half century of basic electric machine study, research, and publication that were reimagined to practical reality by a follow-on regimen of successful BEM R+D, 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., quantum computing) instead of applied as a onetime design tool for research and development. Therefore, under the same CTSR 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 A-EMS by including the associated compounding effects of rotor friction and induced harmonics on the electronic controller, stator, 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) 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), particularly in an axial-flux format with inherently similar adjacent rotor and stator disks assemblies.
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 electrical System of Systems (SoS) application, such as wind turbine farms and electrically propelled ships, airplanes, land vehicles, etc. 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.
