ABOUT OUR WEBSITE
Some say our website is too tedious; but in fact, our technically detailed website is essential to irrefutably verify our patented electric motor system (and synergistic technologies) uniquely shows double price-performance magnification over all others, which is in contrast to our competitors’ fancy (but technically irrelevant) website that is essential to cunningly proclaim their same, me-too electric motor system has better price-performance over all other me-too electric motor systems.
PRODUCT → SYNCHRO-SYM Technologies:
SYNCHRO-SYM is the only “Symmetric” Electric Motor or Generator circuit and control architecture with the optimal symmetry of an “active rotor assembly” that stably, wirelessly, 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” of all electric motors, which is only possible with the patented invention of exact Brushless & Sensorless Real Time Emulation Control (BRTEC). All other electric motor or generator circuit and control architectures have the non-optimal asymmetry of a “passive rotor assembly” with either slip induction dependent windings, reluctance saliencies, rare-earth permanent magnets (RE-PM), or DC field windings that consumes precious electric motor power, real-estate, and cost but cannot contribute additional working power to the electromechanical energy conversion process along with the universally essential active stator assembly, which is only possible with the traditional derivative of estimating field-oriented excitation control (FOC). By simply retrofitting any other high performance electric motor or generator system with the brushless, stable, synchronous, and symmetric circuit and control architecture of SYNCHRO-SYM, which uniquely makes the rotor assembly an additional active power contributor to the electromechanical energy conversion process within the same package of materials, windings, electronic components, manufacturing (less RE-PMs), and port voltage, a century of classic electric motor and generator study already confirmed the power density of the original 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. Also, unlike all other electric motor and generator systems, only SYNCHRO-SYM uniquely favors the employment of wide bandgap (WBG) power semiconductors and comparably performs with the futuristic super permanent magnet (i.e., field wound superconductor) electric motor system but without the loss, cost, and size of cryogenic provisioning.
As the pinnacle of electric motor or generator circuit and control architecture, SYNCHRO-SYM opens the next chapter in e-mobility.
Whatever the publicized cost-performance and power density improvements for any other electric motor system with a given package and port voltage, such as the high power-density of the Koenigsegg Quark E-Motor system package, Magna, Linear Labs, Infinitum, etc., retrofitting the same electric motor system package with the circuit and control architecture of SYNCHRO-SYM will at least double the publicized improvements while lowering cost and conveniently eliminating any exotic RE-PMs.
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 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 or material damage, 3) with perfectly aligned slots and channels of any programmable shape for windings, permanent magnets, reluctance saliencies, or cooling means, and 4) with perfectly flat air-gap surfaces without secondary tooling processes, all of which will revolutionize and democratize the manufacture of superior performing electric motors, generators, and power magnetics, such as electromagnetic transformers, 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, large facility, and oppressed offshored labor.
BMSCC is the only Brushless Bidirectional Multiphase Self-Commutated Controller with a unique isolated, high power, exact inherent resonant switching, 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, which 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, high power, exact inherent resonant switching, 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 but with half the cost, lower harmonic content, and fewer active electronic stages in a system of systems (SoS) application, such as electric vehicles, electric airplanes, etc.
PRODUCT → FOCUS:
A dramatic decline of the internal combustion engine (ICE) vehicle is anticipated with the rapid adoption of the more efficient electric propulsion motor powertrain (e.g., E-mobility), which leaves the electric motor system as the major consumer of EV loss and associated battery range. Efficient and high power density electric propulsion is needed for environmentally friendly and efficient short distance passenger airplanes or for unmanned, long duration, high altitude, solar powered, field maintenance returnable, flying communication platforms for the broadest, most reliable network (e.g., 5G) coverage possible. Modular, lightweight, high power electric generator systems are being explored to reduce field installation and sustainment costs of large offshore wind-turbines. Alone, the electric propulsion motor system market is anticipated to reach $1.4T with a CAGR of 26.7% by 2028 (BB).
Ironically, the entire electric infrastructure industry is approaching this transformation with the same century old, me-too, non-optimal “asymmetric” electric motor or generator circuit and control architecture with a “passive” rotor assembly of rare-earth permanent magnets (RE-PM), slip-induction windings, reluctance saliencies, or DC field windings and their associated provisioning, such as brushes, sliprings, RE-PM reinforcements, conventional or superconductor electromagnets, etc., that consumes precious electric motor and generator system power, cost, and real-estate but without contributing additional working power to the electromechanical energy conversion process. As a result, their performance distinction is limited to: a) empirically applying the same off-the-shelf materials, winding, packaging, and electronic component performance enhancing techniques that results in the same stable Maximum Load RPM (or constant torque speed range) and associated performance for a given port voltage when equally applied between asymmetric electric motor contestants, b) forming alliances with leading innovators to mutually leverage verified empirical packaging techniques, or c) 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 branding virtually the same performing asymmetric electric propulsion motor system.
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) advantageously placed on the rotor and stator, respectively, to maintain the same electric motor footprint of material, cost, and loss. Under the same continuous airgap flux density, frequency, voltage and torque, SYNCHRO-SYM provides at least double the continuous power and octuple the peak torque at half the cost and loss per unit of power rating as the “asymmetric” electric motor circuit and control architecture within the same package of material, winding, electronic component, and manufacturing techniques but without delicate and costly RE-PMs. Also, only BEM is introducing a complementary portfolio of patented technologies, branded SYNCHRO-SYM Technologies, that reduces overall size, improves overall efficiency, and lowers overall cost of an electrical System of Systems (SoS), such as electrically propelled ships, airplanes, and 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 motors and generators, such as SYNCHRO-SYM, and high frequency electric transformers, which are essential for lowering the cost, size and loss of the smart electricity infrastructure and electric propulsion, b) a patented Brushless Bidirectional Multiphase Self-Commutated Controller, which is essential for successfully implementing the smart electricity infrastructure, and c) a patented Bidirectional, Balanced Multiphase, High Frequency, Electricity Micro-Distribution Bus, which is essential for lowering the cost and improving the efficiency of the electric vehicle System of Systems.
PRODUCT → SHOW ME:
MAGNAX uses the century old, me-too asymmetric electric motor system but with some of the highest performance metrics on the market by empirically applying commonly known RE-PM YASA packaging techniques that comprises the asymmetry of a “passive” rotor assembly of rare-earth permanent magnets and an electronic excitation controller derivative of estimating field-oriented control (FOC). By simply retrofitting the asymmetric circuit and control architecture of MAGNAX with the patented brushless and symmetric multiphase doubly-fed electric machine circuit and control architecture of SYNCHRO-SYM, which keeps the MAGNAX active stator assembly but 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 exact synchronous stabilization of a brushless multiphase real time emulation controller (BRTECTM), the power density of the original MAGNAX electric machine system package would comparably double (for up to 10x the power density instead of the MAGNAX’s advertised 5x power density), the cost would comparably halve, the efficiency would comparably increase, and the peak torque would comparably octuple, all by eliminating the FOC and the size, loss, and cost of the passive rotor assembly with the extravagant cost, geopolitical consequence, limited operational life expectancy, wasteful cogging drag, environmentally unfriendly, and safe handling issues of RE-PMs.
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 techniques and port voltage 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 techniques but with double the expective performance gain and as a result, is straight-forward ready,
- But unlike MAGNAX, only the symmetric circuit and control architecture of SYNCHRO-SYM inherently provides: i) universal single AC, multiphase AC, or DC operation, ii) coveted field weakening for extended speed range and electronic control reliability, iii) efficient cogless operation (no RE-PMs), and iv) comprehensive leading, lagging, or unity power factor compensation,
- But unlike MAGNAX, only the symmetric circuit and control architecture of SYNCHRO-SYM best utilizes the axial-flux form factor and emerging wide bandgap electronic semiconductor switches: i) by providing the reliability of BRTEC with inherent resonant switching, by providing direct AC-to-AC conversion due to instantaneous, sensorless, and automatic electromagnetic computing with inherent active filtering that also eliminates the need for a DC Link Stage with banks of large, expensive, inefficient, and delicate low frequency, high power capacitors (e.g., no bulky DC Link capacitors), and iii) by conveniently placing the integral BRTEC within the otherwise wasted annulus of the axial flux core for another level of system power density and component inventory reduction with the same rotor and stator assemblies.
The patented MOTORPRINTER revolutionizes and democratizes the manufacture of axial-flux high frequency and low 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 3D Printing method, which provides a competitive advantage over all other electric machine manufacturers by also, uniquely layering off-the-shelf performance enhancing materials that are optimally premanufactured to be compatible with the resulting electric motor product, such as high performance amorphous or nanocrystalline metal ribbon, structural material, and magnet wire, without material property damage or tool wear, instead of specialized layering materials, such as powders, filaments, etc., that are optimally premanufactured to be compatible with the traditional 3D Printer instead of the product being manufactured.
The patented circuit and control architecture of the Brushless Real Time Emulation Controller (BRTEC) provides several patented hybrid configurations with electromagnetic processing and exact inherent resonant switching. 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.
