PRODUCT →  EXECUTIVE SUMMARY:

In accordance with Our Mission, Best Electric Machine (BEM) provides a collaborative portfolio of patented technologies, branded SYNCHRO-SYM Technologies, for transforming the electric transportation, such as automobiles, airplanes, ships, and trains, the renewable energy, such as hydrogen, wind, tidal, and solar, and the smart electricity infrastructures, such as synchro-phasors, synchronous machines, automatic power grid frequency synchronizers, and distributed power factor correctors.

PRODUCT → SYNCHRO-SYM Technologies:

SYNCHRO-SYM is a patented “Symmetric” Electric Motor or Generator System circuit and control topology providing an “active” rotor assembly that effectively doubles the power density, shows octuple the peak torque density, halves the cost, and halves the loss within the same package of all other electric machine systems with a “passive” rotor assembly of slip induction dependent windings, reluctance saliencies, permanent magnets, or dc field windings, all while leaving the inadequate and geopolitically sensitive global supply of rare-earth (RE) permanent magnet materials (RE-PM) available for other more strategic applications.

MOTORPRINTER is a patented 3D Printer Method for the rapid additive manufacture of low and high frequency, high power, axial flux electric machine cores with 1) 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, and 4) with integral frame and winding assemblies; thereby, democratizing the manufacture of superior performing electric motor and generator systems.

BM-HFMDB is a patented Bi-directional, Balanced 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.

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

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 electric propulsion for airplanes is quickly becoming a practical reality. Modular lightweight electric generator systems for large offshore wind-turbines are being explored. Industry is approaching this transformation without changing the century old, me-too, “asymmetric” electric motor or generator circuit and control architecture with the asymmetry of a “passive” rotor assembly of slip-induction windings, reluctance saliencies, rare-earth permanent magnets (RE-PM), or DC field windings; but instead, by improving its cost-performance with better materials, winding and packaging techniques, such as the emerging electric machine systems from MAGNAX and MAGNIX, by forming alliances with leading innovators, such as EM-motive, or by 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 axial flux “symmetric” electric motor or generator system, called SYNCHRO-SYM, with the symmetry of an “active” rotor assembly that at least doubles the performance of the “asymmetric” electric machine system while using the same material, winding, packaging and manufacturing techniques.  Also, 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 electric motors, generators, and high frequency transformers.

PRODUCT →  SHOW ME:

By simply retrofitting the century old asymmetric electric machine circuit and control architecture package of MAGNAX, which was only enhanced with the commonly available RE-PM YASA packaging form that comprises: 1) a so-called yokeless “active” stator assembly with the directly excited multiphase winding set, 2) a “passive” rotor assembly of rare-earth permanent magnets (i.e., singly-fed), and 3) an electronic controller derivative of field oriented control (FOC), instead with the patented, integrated, brushless, multiphase, and symmetric 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) of SYNCHRO-SYM (i.e., synchronous symmetrical doubly-fed), then simple conceptual observation shows the power density of the original, highly package optimized MAGNAX electric machine system would again 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, and the peak torque would at least comparably quadruple per unit of power rating, all while eliminating the extravagant cost, safety and handling issues of rare-earth permanent magnets with persistent magnetism, geopolitical consequences, limited operational life expectancy, and environmentally unfriendly production.

The simple retrofit comparison between the original MAGNAX and SYNCHRO-SYM also conveniently shows: 1) SYNCHRO-SYM operation, design, construction, and manufacture are straight-forward ready (like MAGNAX), 2) SYNCHRO-SYM uses off-the-shelf components (like MAGNAX) but without exotic components or materials, such as rare earth permanent magnets, 3) SYNCHRO-SYM is adaptable to legacy, off-the-shelf, fielded, or future electric machine systems with customary engineering and manufacturing (like MAGNAX), and 4) SYNCHRO-SYM easily leverages third party legacy or future electric machine design, packaging, material, winding, or construction techniques (as used by MAGNAX) but with double the effective performance results.
