BEST ELECTRIC MACHINE → BOTTOM LINE UP FRONT
Our flagship product, SYNCHRO-SYM™, is the only magnet-free, drop-in replacement for today’s variable-speed electric motor-generator systems (EMS)—including in-wheel motor systems—that eliminates delicate rare-earth permanent magnets (RE-PM) with harmful cogging drag and geopolitical consequences but at the same time, matchlessly enables: a) 2× to 8× the performance-per-dollar, b) higher efficiency, c) less copper (or aluminum) windings and electrical steel per kilowatt, and c) 8× peak torque-capability for realistically enabling next-generation electric vehicles (EV) electromagnetic gearing and braking.
SYNCHRO-SYMTM is technically proven and ready for immediate commercialization with rapid, reprogrammable, stateside additive manufacturing (3D Printed motors), a truly software-defined EMS targeted for 2026.
“Where “all others” claim extraordinary performance improvement by meaninglessly benchmarking their selection of optimize legacy packaging against raw, off-the-shelf, standardized AC motors, SYNCHRO-SYM benchmarks truly unmatched performance against “all others” — validated by fundamental physics of electromagnetic symmetry where both rotor and stator work together.”
“SYNCHRO-SYM does not out-market competitors — It out-measures them.”
Fundamentally arising from the inherent circuit and control asymmetry of an active stator with an independently excited multiphase winding set (active winding set) paired with a passive rotor using permanent magnets (PM), reluctance saliencies, DC field windings, or slip-induction windings, and governed by offline compensatory derivatives of field-oriented control (FOC) or direct-torque control (DTC), the asymmetric electric-machine system (A-EMS) architecture of today is intrinsically constrained in scalability, power density, and core utilization.
Free from today’s EMS constraints, only SYNCHRO-SYM™ scales across EV, wind, aerospace, and commercial applications by providing the only “symmetric” electric motor-generator system (S-EMS):
Active Stator + Active Rotor Symmetry — both halves independently deliver working power to the electromechanical conversion, performance-to-price grounded in physics—not marketing spin.
Brushless Real Time Emulation Control (BRTEC™) — compact solid-state, quantum level stabilization with a novel brushless, symmetrically bidirectional, inherent soft switching, pure sinusoidal, direct AC-to-AC power conversion method at half the current rating; no bulky, costly DC link stage — inherently providing full rotor and stator metrics for superior reliance and automatic sensor-less optimization. Highly adaptable, BRTEC conveniently enables an ultra-high-performance, symmetrically bi-directional, multiphase, isolated EV micro-distribution bus and battery recharger.
Integrally unified electric motor-generator and control technology — not the mated, disparate circuit and control technologies of today’s A-EMS, evolving from different disciplines — compact solid-state BRTEC fits within the axial-flux annulus for another level of integration and power density.
Just-In-Time Additive Manufacturing — enables rapid, scalable, cost-effective, and reprogrammable production with MOTORPRINTER™, the only electric motor 3D Printer Method, and BEM-CAD™, the only EMS CAD with SYNCHRO-SYM extension and cross-analysis.
Future-Ready Architecture — most compatible symmetric circuit and control technology for retrofitting the next-generation EMS, including the superconductor EMS.
Expert-Driven Culture — engineering excellence, customer focus, and principled innovation.
SYNCHRO‑SYM™ EMS —The Ultimate EMS
Instead of the passive rotor used by all others, only SYNCHRO-SYM™ uniquely employs an active rotor that symmetrically delivers additional working power to the electromechanical energy-conversion process, together with the universally required active stator; fundamental physics of electromagnetic symmetry dictates higher power, higher efficiency, and lower cost within the same physical packaging, without reliance on rare-earth permanent magnets or air-gap-area-robbing reluctance saliencies.
Nothing Like it—Brushless, drop-in replacement with no rare-earth magnets but immediate 2x nominal power, 8x peak torque, 98% nominal efficiency—ethically built in the USA.
Every SYNCHRO‑SYM™ purchase is more than an EMS purchase—it’s an investment in “Real Innovation for Our Clean, Efficient, and Sustainable Energy Future.”
Every EMS product purchase today—especially the constant wave of so-called advanced high-performance EMS designs—ultimately delivers another “same-old” EMS claiming performance-to-price advantage through marketing hype and flashy visuals that merely insinuate a technology breakthrough.
The EMS of today relies on the same non-optimal asymmetric electric motor-generator system circuit and control architecture (A-EMS)—an “active-stator” with an independently-excited multiphase winding set (active winding set) that solely delivers the working power to the electromechanical power conversion process, paired with a “passive-rotor” using RE-PMs, slip-induction windings, field windings, or reluctance saliencies that cannot deliver working power but consumes the other half of motor size, loss, and cost in cascade with the active stator, and glued together by a disparate, estimation-dependent, high harmonic content, compensatory field-oriented control (FOC) derivative—performance-to-price distinction relies on unfairly exploiting the design specification or re-engineering the empirical selection of legacy packaging techniques without allowing the same opportunity to contestants—physics dictates similar nominal performance-to-price results if packaging and design specifications are equally applied.
The EMS of today is built from essential but separately distinct components—electric motor, electronic controller, and if needed, high maintenance and lossy gearbox—all from different technical disciplines without shared understanding—often from different manufacturing sources with so-called “integration” amounting to little more than adjacent placement. Depending on which component is referenced, the compounded losses, costs, and size of these essential components are often overlooked in the real-world “system of systems” performance—leaving EMS customers misled and frustrated. Note: The gearbox reduces the amount of costly rare-earth permanent magnets (RE-PM) by enabling a smaller, higher speed motor to achieve reasonable application torque.
A Best Electric Machine (BEM) SYNCHRO‑SYM™ product purchase—provides a fundamentally different EMS—delivering superior performance-to-price advantage over all others by applying real innovation grounded in the principles of physics instead of marketing spin.
Our patented SYNCHRO‑SYM™ makes a commercial reality of the long-theorized and most optimal symmetric electric motor-generator system circuit and control architecture (S-EMS)—brushless dual-active power conversion of an active stator and active rotor—only possible by our patented, integrally unified, solid-state, brushless, sensor-less, pure sinusoidal Real-Time Emulation Control (BRTEC)—enables both rotor and stator to independently and stably combine working power to the electromechanical power conversion while consuming half of motor size, loss, and cost—physics dictates 2× the nominal performance-to-price and 8× the torque performance of the passive-rotor A-EMS of today with similar design specifications and packaging.
Our patented SYNCHRO‑SYM™ is an integrally unified circuit and control system—never sold separately—always factoring the added losses, costs, and size of every system part for real world performance, including BRTEC.
Our patented Brushless Real Time Emulation Control (BRTEC™)—compact solid-state, quantum level stabilization with inherent symmetrically soft switch, pure sinusoidal, direct AC-to-AC power conversion at half the current rating; no bulky, costly DC link stage—inherently providing full rotor and stator metrics in real-time for superior operation and integrally unified into the frame for another level of EMS power-density. Highly adaptable, BRTEC conveniently enables an ultra-high-performance, symmetrically bi-directional, multiphase, isolated electric vehicle (EV) micro-distribution bus and battery recharger—doubling the performance-to-price advantage of WBG semiconductors.
By simulating a BRTEC means for stability, the S-EMS continues to be the foundational study behind A-EMS and packaging technologies of today by deoptimizing its symmetry with the asymmetry of a passive rotor + FOC. Accordingly, over a half-century of classical laboratory research already validated 2× to 8× performance-to-price and torque of any A-EMS package retrofitted with the S-EMS circuit and control technology (e.g., active rotor + BRTEC)—reducing losses, constraining core saturation, eliminating the need for rare-earth magnets, slashing strategic materials, such as copper or aluminum, per kW, and realistically enabling maintenance-free, tunable, gearless electromagnetic transmission & electromagnetic braking. Note: Never realizing the practical BRTEC invention (until SYNCHRO‑SYM™), the higher performing S-EMS was sidelined by the timely invention of the high-energy product RE-PM (circa 1980) for a practical RE-PM A-EMS with unforeseen environmental, unsustainable, and geopolitical consequences of its widespread adoption. Despite SYNCHRO-SYM™ already demonstrating a practical S-EMS, the industry remains blind to its existence, because SYNCHRO-SYM™ is repeatedly mistaken for familiar A-EMS variants with legacy packaging techniques and geometries: wound-rotor doubly-fed “induction” machines with passive multiphase rotor windings, brushless doubly-fed designs with unlike pole-pairs, or so-called ‘symmetric’ A-EMS (e.g., DeepDrive) that rely on nothing more than legacy, geometric dual-rotor or dual-stator symmetry with the expanded package size, loss, and cost of two highly integrated motors.
Only SYNCHRO‑SYM™ is a drop-in replacement to today’s A-EMS—including any in-wheel EMS—but uniquely with more power, more torque, more efficiency, and no rare-earth permanent magnets.
Only SYNCHRO‑SYM is a no-brainer upgrade to today’s advanced, externally excited field-wound synchronous A-EMS—providing the same RE-PM-free benefits but with far superior performance.
Only SYNCHRO-SYM provides superior performance in rare-earth-free, low-speed, high-power direct-drive applications—operating regimes historically constrained to rare-earth permanent-magnet machines due to the torque-density, efficiency, and core saturation limitations of conventional passive-rotor alternatives.
Only SYNCHRO‑SYM is the realistic software-defined EMS, as only possible with the symmetry of an integral active rotor electric motor-generator circuit and integrally-unified control technology—the so-called software-defined EMS of others is built with the deoptimized asymmetry of separate, adjacently mounted, passive rotor circuit and externally mounted control components.
Only SYNCHRO‑SYM will be the future’s EMS of choice—even enabling the practical reality of superconductor packaging techniques that establish air-gap flux density beyond the supporting limits of core material.
“While all others continue the hard work of optimizing legacy EMS packaging geometry using century old asymmetric circuit and control technology with a passive rotor of slip-induction, rare-earth permanent magnets, reluctance saliencies, or DC field windings,” said Frederick W. Klatt, CTO of BEM, “Only BEM did the hard work of inventing, researching, developing, engineering, and manufacturing the optimum symmetric circuit and control technology with an active rotor, called SYNCHRO-SYMTM, that uses the same optimized A-EMS package geometry yet doubles the nominal power rating and halves the cost and loss per kW with both rotor and stator working together.”
A BEM SYNCHRO-SYM product purchase—means quick, secure inhouse, additive manufacturing by our patented MOTORPRINTER™ 3D Printing method, called MOTORPRINTER™—reprogrammed by BEM’s computer aided design tool (BEM-CAD)—all other EMS manufacturing relies on the same-old subtractive manufacturing methods, perhaps supplemented with automation.
Only MOTORPRINTER™ enables just-in-time customization – Allows rapid, just-in-time adaptation to specific customer needs.
Only MOTORPRINTER™ enables proprietary SYNCHRO-SYM™ direct cooling with unmatched thermal management for superior performance.
Only MOTORPRINTER™ enables system advantages – Delivers higher reliability, significantly lower cost, greater power density, and higher specific power compared to conventional methods.
Only MOTORPRINTER™ enables advanced materials integration – Enables practical use of exotic, high-performance materials, such as thin amorphous or nano-crystalline ribbon, previously impractical in motor manufacturing, while eliminating the price premium typically associated with complex axial-flux electromechanical structures.
A BEM SYNCHRO-SYM product purchase—means working with our lean, expert-driven team culture that prioritizes customer satisfaction, engineering excellence and genuine innovation—uniquely delivering a truly groundbreaking S-EMS solution. Unlike today’s A-EMS product purchase that prioritizes flashy branding and marketing spin but delivers the same-old A-EMS solution as new and innovated.
Only BEM established a higher-purpose commercialization framework to bring the next-generation brushless axial-flux SYNCHRO-SYM™ to market—targeting the $100B EV propulsion market—correctly including the complete EMS system cost, not just the motor-generator. BEM also plans to expand into the $200B industrial EMS market.
Only SYNCHRO‑SYM™ represents one of the single biggest opportunities to accelerate our clean, efficient, and sustainable energy future—Both the battery and the EMS account for 30–40% of the EV’s total cost-of-goods with an equally significant impact on performance, price, and sustainability. With 85% of EVs still relying on rare-earth permanent magnets (RE-PMs) EMS, switching to SYNCHRO-SYM™ delivers a step-change-improvement in efficiency, power density, and cost.
Only SYNCHRO‑SYM™ offers significantly higher-performance and an ethically sound alternative to the RE-PM-based A-EMS—anecdotally regarded by practitioners as the best EMS but unethically monopolized by geopolitical adversaries causing alarming environmental, labor, supply chain, and geopolitical risks. By eliminating the RE-PM array from the EMS with a better performing solution, SYNCHRO‑SYM™ redirects a majority of these scarce materials to other strategic applications and mitigates the sustainability of global mineable reserves.
Only SYNCHRO‑SYM™ delivers the industry’s lowest-carbon-footprint EMS—uniting magnet-free SYNCHRO-SYM™’s unmatched efficiency, power density, and lowest cost with MOTORPRINTER™’s additive manufacturing.
Instead of the passive rotor used by all others, only SYNCHRO-SYM™ uniquely employs an active rotor that symmetrically delivers additional working power to the electromechanical energy-conversion process, together with the universally required active stator; fundamental physics of electromagnetic symmetry dictates higher power, higher efficiency, and lower cost within the same physical packaging, without reliance on rare-earth permanent magnets or air-gap-area-robbing reluctance saliencies.
Nothing Like it—Brushless, drop-in replacement with no rare-earth magnets but immediate 2x nominal power, 8x peak torque, 98% nominal efficiency—ethically built in the USA.

Instead of the passive rotor used by all others, only SYNCHRO-SYM™ uniquely employs an active rotor that symmetrically delivers additional working power to the electromechanical energy-conversion process, together with the universally required active stator; fundamental physics of electromagnetic symmetry dictates higher power, higher efficiency, and lower cost within the same physical packaging, without reliance on rare-earth permanent magnets or air-gap-area-robbing reluctance saliencies.
Nothing Like it—Brushless, drop-in replacement with no rare-earth magnets but immediate 2x nominal power, 8x peak torque, 98% nominal efficiency—ethically built in the USA.
Every SYNCHRO‑SYM™ purchase is more than an EMS purchase—it’s an investment in “Real Innovation for Our Clean, Efficient, and Sustainable Energy Future.”
Providing the only EMS with an active rotor in the same A-EMS package footprint—contributing additional working power alongside the active stator—SYNCHRO-SYM™ eliminates reliance on exotic RE-PMs or costly Halbach magnet arrangements—delivering breakthrough performance at the world’s lowest cost per unit of power. Employing a time-proven axial-flux form factor, engineered using BEM-CAD and manufactured in-house with BEM’s rapid just-in-time, programmable MOTORPRINTER™, SYNCHRO-SYM™ is now available for purchase with a transparent, well-defined price and delivery schedule—clearly distinguishing it from asymmetric EMS competitors that rely on creative marketing, offshore manufacturing, and opaque price-delivery negotiations.
For more demanding applications, BEM-CAD enables the custom design of novel, brushless axial-flux SYNCHRO-SYM™ that achieve the world’s lowest cost per unit of power at the customer’s required performance point and minimum purchase volume. BEM-CAD likewise enables superior low-speed, high-power SYNCHRO-SYM™ for RE-PM-free direct-drive systems, including wind-turbine applications.
BEM-CAD confirms our “novel” brushless 280 kW (continuous duty) or 560 kW (peak duty/gearless 2675Nm torque) @ 2000 RPM constant-torque-speed-range (CTSR) Axial-Flux SYNCHRO-SYM is the unmatched rival to Koenigsegg’s Quark E-Motor—speeds beyond CTSR enter the constant-power-speed-range (CPSR)—delivering the world’s lowest-cost per unit of power while exceeding both continuous and peak ratings under similar operating conditions, fully aligned with the criteria for equitable EMS cross-comparison.
Operating Conditions: 400-800V
CTSR: 2000 RPM
Peak System Efficiency @ CTSR: 98%
Cost per kW at peak power: see EMS Early-Access(vs. Koenigsegg: N/A)
Burst Power Density: >83 kW/L (@ CTSR vs. Koenigsegg’s 32 kW/L@ 4000RPM)
Burst Specific Power: >21 kW/kg (@ CTSR vs. Koenigsegg’s 8.7 kW/kg@ 4000RPM)

Dimension: Diameter: 300mm (11 in.) x Length: 94mm (3.7 in.) x Weight: 27Kg (59 lbs.)
Note: Pricing will be provided upon request.
Note: CTSR is the speed range where rated or burst torque can be applied. Operation above CTSR enters the constant-horsepower speed range (CPSR) where rated or burst torque must be linearly reduced with increasing speed. The “motor CTSR” and torque determines the need for additional gearing to met the load CTSR and torque—let BEM design SYNCHRO-SYM to meet your load CTSR without a gearbox.
Note: “Maximum Speed” is often flaunted as a performance metric, but it is really just the upper mechanical limit before dynamic failure, offering little insight into usable performance.
Note: As the only unified, turnkey electric motor-generator circuit and control system, SYNCHRO-SYM’s controller and electric machine components cannot be sold separately—the loss, size, weight, and cost of our integral BRTEC controller are always included in SYNCHRO-SYM performance results.
Note: A meaningful comparison requires EMS contestants to be evaluated at the same CTSR. Only under these equal conditions do true comparisons emerge, such as the EMS peak power density, peak specific power, peak torque, system cost, and peak nominal efficiency at the same safe-operating burst duration (at least 10 seconds with rated active cooling, which is the real-world acceleration window).
Note: Upon customer request, BEM-CAD can reprogram MOTORPRINTER™ just-in-time to build SYNCHRO-SYM™ with unmatched efficiency or power density.
