PRODUCT → SYNCHRO-SYM Technologies:

SYNCHRO-SYM is a patented Brushless “Symmetric” Electric Motor or Generator circuit and control architecture with the uniqueness of an “active” rotor assembly that stably contributes additional working power to the electromechanical energy conversion process together with the essential active stator assembly. With the reasonable assumption that the rotor assembly consumes half of the electric motor or generator real estate, loss, and cost within the same package of performance enhancing material, winding, and electronic component techniques, SYNCHRO-SYM obviously provides half the size (or twice the power density), half the cost, half the loss, and octuple the peak torque density per unit of power rating of all other electric motor or generator circuit and control architectures with the non-optimum asymmetry of a “passive” rotor assembly of slip induction dependent windings, reluctance saliencies, rare-earth permanent magnets, or DC or single-phase field windings that consume up to half of the real-estate, loss, and cost but without compensating with additional working power to the electromechanical energy conversion process.

MOTORPRINTER is a patented 3D Printer Method for the rapid additive manufacture of low and high frequency, high power, axial-flux electric machine cores: 1) with the highest performing electrical steel, amorphous metal, or nanocrystalline metal ribbon that have been impractical with conventional electric machine manufacturing, 2) with perfectly aligned slots of any programmable shape for windings, permanent magnets, reluctance saliencies, or cooling means, 3) with perfectly flat air-gap surfaces without secondary tooling processes, and 4) with integral frame and winding assemblies, all of which will democratize the manufacture of superior performing electric motor and generator systems.

BMSCC is a patented hybrid Brushless Bi-directional Multiphase Self-Commutated Controller with a new symmetric magnetic sharing circuit and control architecture that provides the most Versatile Smart Power Converter products but with the lowest cost, highest efficiency, highest power density possible, such as a Bi-Directional Multiphase Inductive (Wireless) Power Transfer System (M-IPTS).

BM-HFMDB is a patented hybrid Bi-directional, Multiphase, High Frequency, Electricity Micro-Distribution Bus with a new symmetric magnetic sharing circuit and control architecture that provides the most versatile micro-distribution bus with the highest efficiency but with half the cost, considerably higher power density, lower harmonic content, and fewer electronic stages in a system of systems (SoS) application, such as electric vehicles, electric airplanes, etc., with multiple SYNCHRO-SYMs or BMSCCs.

PRODUCT →  FOCUS:

A dramatic decline of the internal combustion engine (ICE) vehicle is predicted with the rapid adoption of the efficient electric motor or generator powertrain as the only practical alternative (e.g., E-mobility). Efficient and high power density electric propulsion for higher and longer flying manned or unmanned airplanes is quickly becoming a practical reality. Modular, lightweight, high power electric generator systems for large offshore wind-turbines are being explored to reduce installation and sustainment cost. The entire industry is approaching this transformation without changing the century old, me-too, “asymmetric” electric motor or generator circuit and control architecture with the non-optimal asymmetry of a “passive” rotor assembly of slip-induction windings, reluctance saliencies, DC field windings (e.g., brush, brushless, conventional and superconductor), or rare-earth permanent magnets (RE-PM), such as the emerging electric machine systems from MAGNAX and MAGNIX, with its overall improvement limited to: a) strategically applying the same off-the-shelf materials, winding, and packaging techniques for the same Maximum Load RPM (or constant torque speed range) results, b) forming alliances with leading innovators, such as EM-motive, or c) investing in “innovative” cost reducing manufacturing methods, such as NIDEC’s $1.8 billion investment in high volume electric vehicle motor manufacturing.

Only BEM is introducing a patented “brushless & symmetric” electric motor or generator system, called SYNCHRO-SYM, with a new circuit and control architecture comprising the optimal symmetry of an “active” rotor assembly that at least doubles the performance of the “asymmetric” electric machine system per unit of power rating, while providing the best fault tolerance expected of multiple phases that do not rely on slip-induction, reluctance, or rare earth permanent magnets and also providing twice the performance improvement of strategically applying the same available material, winding, packaging, and manufacturing techniques to asymmetric electric machine systems.  Only BEM is investing in a patented electric machine 3D Printing technology, called MOTORPRINTER, for revolutionizing and democratizing the rapid just-in-time additive manufacture of superior performing axial-flux, low and high frequency, electric motors, generators, and transformers, which are essential for implementing lower cost, size, and cost smart electricity. Only BEM is investing in a patented Brushless Bi-directional Multiphase Self-Commutated Controller, which is essential for the smart electricity infrastructure. Only BEM is investing in a patented Bi-directional, Balanced Multiphase, High Frequency, Electricity Micro-Distribution Bus, which is essential for lowering the cost and improving the efficiency of the overall electric vehicle System of Systems.

PRODUCT →  SHOW ME:

By simply retrofitting the century old asymmetric electric machine circuit and control architecture of MAGNAX, which was only enhanced with the commonly known RE-PM YASA packaging that comprises: 1) a so-called yokeless “active” stator assembly with a single directly excited multiphase winding set (i.e., singly-fed), 2) a “passive” rotor assembly of rare-earth permanent magnets, and 3) an electronic controller derivative of field oriented control (FOC), instead with the patented, integrated, brushless, multiphase, and symmetric doubly-fed electric machine circuit and control architecture of SYNCHRO-SYM, which keeps the MAGNAX active stator assembly but replaces the MAGNAX passive rotor assembly and FOC with an “active rotor assembly” as only possible with the brushless multiphase real time emulation controller (BRTEC), simple qualitative observation shows the power density of the original MAGNAX electric machine system package would comparably double (with both the stator and rotor volumes equally contributing power to electromechanical conversion process), the cost would comparably halve per unit of power rating, the efficiency would comparably increase per unit of power rating, the peak torque would at least comparably quadruple per unit of power rating, and the performance improvements from strategically applying specialized materials, winding, and packaging techniques would be twice magnified, all while eliminating the extravagant cost, safety and handling, persistent magnetism, geopolitical consequences, limited operational life expectancy, and environmentally unfriendly production issues of rare-earth permanent magnets.

The simple retrofit comparison between the “symmetric” circuit and control architecture of SYNCHRO-SYM, which in accordance with the classic study of electric motors and generators is the pinnacle of electric motor or generator circuit and control technology by comprising “active” winding sets on the rotor and stator, respectively, as only possible by a brushless, real time emulation control method for stabilization, and the original “asymmetric” circuit and control architecture from MAGNAX, which comprises an active stator but a “passive” rotor of rare-earth permanent magnets, conveniently shows:

  1. Like MAGNAX, SYNCHRO-SYM material, winding, and packaging techniques are well understood with nearly two centuries of evolution,
  2. Like MAGNAX, SYNCHRO-SYM operation, design, construction, and manufacture are straight-forward ready,
  3. Like MAGNAX, SYNCHRO-SYM uses off-the-shelf components but unlike MAGNAX, SYNCHRO-SYM is without exotic materials, such as rare earth permanent magnets,
  4. Like MAGNAX, SYNCHRO-SYM is adaptable to legacy, off-the-shelf, fielded, or future electric machine systems with customary engineering and manufacturing,
  5. Like MAGNAX (and the next generation of optimized asymmetric motors from EMRAX, British YASA, DENSO, Turntide Technologies, Mahle, etc.), SYNCHRO-SYM easily leverages third party legacy or future electric machine design, packaging, material, winding, or construction techniques but with double the effective performance results,
  6. Unlike MAGNAX, only the symmetric circuit and control architecture of SYNCHRO-SYM best utilizes the axial-flux form factor by conveniently locating the integral BRTEC within the otherwise wasted annulus of the axial flux core for another level of power density and uniquely providing the same assembly for rotor or stator for inventory reduction.

The patented MOTORPRINTER uniquely democratizes the manufacture of axial-flux electric machines with a compact, scalable, low waste, non-smokestack 3D Printing method (or additive manufacturing method) that just-in-time manufactures high frequency (HF) and low frequency (LF) electric motors, generators, and transformers with compatible high performance amorphous or nanocrystalline metal ribbon, such as found in SYNCHRO-SYM, which provides a competitive advantage over all other electric machine manufacturers, such as BEM in particular with SYNCHRO-SYM.

The patented circuit and control architecture of the Brushless Real Time Emulation Controller (BRTEC) provides several patented hybrid configurations with electromagnetic processing. For instance, the patented BM-HFMDB provides the power connection between multiple SYNCHRO-SYMs in a system of system (such as 4 independent wheel motors in an electric vehicle or EV) 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 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.
