BEST ELECTRIC MACHINE → BOTTOM LINE UP FRONT
Our flagship product, SYNCHRO-SYM™, is the only magnet-free, drop-in replacement for any of today’s variable-speed electric motor-generator systems (E-Motor)—including in-wheel motor systems—that eliminates rare-earth permanent magnets (RE-PM) with cogging and drag but at the same time, matchlessly enables: a) 2× to 8× the performance-per-dollar and torque at the same voltage and frequency, b) better efficiency, c) less copper (or aluminum) windings and electrical steel per kilowatt, simple control without the bulky DC link stage, and d) next-generation electric vehicles (EV) with tunable, maintenance-free, low wear, electromagnetic gearing and braking from highest peak torque capability.
SYNCHRO-SYMTM is technically proven and ready for immediate commercialization with rapid, reprogrammable, stateside additive manufacturing (3D Printed motors), targeted for 2026.
“Where competitors rearrange package geometry, we optimize to the physics,” said Frederick W. Klatt, CTO of BEM. “Only SYNCHRO-SYM technology doubles the real nominal working power, improves efficiency and lowers cost from the same package geometry because both sides of the machine work. It’s the only technology that breaks the rare-earth permanent-magnet bottleneck without sacrificing performance.”
Free from today’s E-Motors constraints—limited by the circuit and control asymmetry of an Active Stator with an independently-excited multiphase winding set (active winding set) + Passive Rotor using permanent magnets (PM), reluctance saliencies, DC field windings, or slip-induction windings, and controlled by a derivative of field-oriented control (FOC)—only SYNCHRO-SYM™ scales across EV, wind, aerospace, and commercial applications by providing:
- 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™) — solid-state, quantum level stabilization with a novel brushless, solid-state, 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 E-Motors evolving from different disciplines.
- Magnet-Free Operation — eliminates rare-earth PM (RE-PM) dependence, avoiding alarming cost, environmental harm, unsustainable, and geopolitical risk.
- 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 CAD with SYNCHRO-SYM extension and cross-analysis.
- Future-Ready Architecture — most compatible symmetric circuit and control technology for retrofitting next-generation E-Motors, including superconductors.
- Expert-Driven Culture — engineering excellence, customer focus, and principled innovation.
SYNCHRO‑SYM™ E-Motor — The Ultimate E-Motor
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 E-Motor—it’s an investment in “Real Innovation for Our Clean, Efficient, and Sustainable Energy Future.”
BEST ELECTRIC MACHINE → SYNCHRO-SYM™ DELIVERS
Every E-Motor product purchase today—especially the constant wave of so-called advanced high-performance E-Motor designs—ultimately delivers another “same-old” E-Motor claiming performance-to-price advantage through marketing hype and flashy visuals that merely insinuate a technology breakthrough.
- All of today’s E-Motors rely 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 singularly 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.
- All of today’s E-Motors are built from essential but separately distinct components—electric motor, electronic controller, and if needed, high maintenance and lossy gears to reduce the amount of costly rare-earth permanent magnets (RE-PM) with a smaller, higher speed motor or to achieve reasonable torque—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 E-Motor customers misled and frustrated.
A Best Electric Machine (BEM) E-Motor product purchase—provides a fundamentally different E-Motor—SYNCHRO‑SYM™—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 contribute additional working power to the electromechanical power conversion while consuming half of motor size, loss, and cost—physics dictates 2× to 8× the nominal performance-to-price and torque of any of today’s passive-rotor A-EMS E-Motor 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™)—solid-state, quantum level stabilization with inherent symmetrically soft switch, pure sinusoidal, solid-state, 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. 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.
A BEM E-Motor product purchase—provides the world’s first and only practical S-EMS product.
- By hypothesizing a BRTEC means for stability, the S-EMS continues to be the foundational study behind A-EMS E-Motor 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 E-Motor package retrofitted with the S-EMS circuit and control technology (e.g., active rotor + BRTEC)—reducing losses, 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, despite the then-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. Practitioners continue assembling off-the-shelf A-EMS components, and theorists still insist an S-EMS is impossible—largely 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 any A-EMS E-Motor—including in-wheel E-Motors—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 E-Motors—providing the same RE-PM-free benefits but with far superior performance.
- Only SYNCHRO‑SYM™ is the realistic software E-Motor, as only possible with the symmetry of an integral active rotor electric motor-generator circuit and control technology—all other so-called software E-Motors are built with the deoptimized asymmetry of separate, adjacently mounted, passive rotor circuit and control components.
- Only SYNCHRO‑SYM™ will be the future’s E-Motor 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 E-Motor 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 E-Motor package geometry yet in accordance with physics, doubles the nominal power rating and halves the cost and loss per kW.”
A BEM E-Motor 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 E-Motor manufacturing relies on the same-old subtractive manufacturing methods, perhaps supplemented with automation.
- Just-in-time customization – Allows rapid, just-in-time adaptation to specific customer needs.
- Proprietary SYNCHRO-SYM™ direct cooling – Provides unmatched thermal management for superior performance.
- System advantages – Delivers higher reliability, significantly lower cost, greater power density, and higher specific power compared to conventional methods.
- 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 E-Motor 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 E-Motor solution. Unlike today’s A-EMS E-Motor product purchase that prioritizes flashy branding and marketing spin—delivering the same-old A-EMS E-Motor solution as new and innovated.
- Established a higher-purpose commercialization framework to bring the next-generation brushless axial-flux SYNCHRO-SYM™ E-Motor to market—targeting the $100B EV propulsion market—correctly including the complete E-Motor system cost, not just motor. BEM also plans to expand into the $200B industrial E-Motor market.
A BEM E-Motor product purchase—above all, operates from principle.
- Only SYNCHRO‑SYM™ represents one of the single biggest opportunities to accelerate our clean, efficient, and sustainable energy future—Contrary to common belief, both the battery and the E-Motor account for 30–40% of the EV’s total cost with an equally significant impact on performance, price, and sustainability. With 85% of EVs still relying on rare-earth permanent magnets (RE-PMs) E-Motors, 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 E-Motor—anecdotally regarded by practitioners as the best E-Motor but unethically monopolized by geopolitical adversaries causing alarming environmental, labor, supply chain, and geopolitical risks. By eliminating RE-PMs E-Motors 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 E-Motor—uniting magnet-free SYNCHRO-SYM™’s unmatched efficiency, power density, and lowest cost with MOTORPRINTER™’s additive manufacturing.

BEST ELECTRIC MACHINE → SYNCHRO-SYM™ PRODUCTS
BEM’s internal market analysis and BEM-CAD simulations confirmed the unusually well specified performance claims of Koenigsegg’s 4000 RPM, 20 second, 800v, 250 kW Peak, Quark E-Motor (3 phase, 8 Liter)—widely regarded as one of the best-performing examples of the “same-old” RE-PM A-EMS E-Motor for the electric vehicle (EV) category, yet despite its highest-performance, the Quark E-Motor is prohibitively expensive for broad commercialization. Even well-funded RE-PM A-EMS E-Motor efforts for electric aircraft propulsion—like MagniX, H3X Technologies, and MIT’s Megawatt Motor—continue to struggle in matching Koenigsegg’s power density, specific power, and efficiency, despite similarly pushing the limits of legacy packaging through better materials, winding schemes, formfactors, and electronic components. Recently, Koenigsegg introduced the 5,000 RPM, 20 second, 800v, 800 HP Peak, “Dark Matter” E-Motor (6 phase, 19.8 Liter)—an attempt to keep pace with the creative marketing surrounding the wave of advanced A-EMS E-Motor introductions. Yet, physics dictates all yield similar nominal performance-to-price results when packaging and design specifications are equally applied.
Providing the only E-Motor with an active rotor in the same A-EMS package—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. Engineered with time-proven axial-flux design and manufactured in-house with BEM’s just-in-time, programmable MOTORPRINTER™, SYNCHRO-SYM™ is now available for purchase with a transparent, well-defined price and delivery schedule—standing apart from competitors who rely on creative marketing and hidden price-delivery negotiations.
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 E-Motor 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 cross-comparison between E-Motors.
- Operating Conditions: 400-800V
- Peak System Efficiency @ CTSR: 98%
- Cost per kW at peak power: see E-Motor Early-Access (vs. Koenigsegg: N/A)

- Gearless Burst Torque (>20 sec safe-operating-area time): maintenance free, direct-drive 2675 Nm, 1973 ft-lb (@ CTSR vs. Koenigsegg: 600 Nm, 443 ft-lb @ 4000RPM)
- Burst Power Density: 83 kW/L (@ CTSR vs. Koenigsegg’s 32 kW/L @ 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 with associated loss, cost, and size to meet the load CTSR and torque, which compounds the loss, cost and size of the essential system of systems (SoS) components, such as electric motor-generator, controller, and gears—let BEM design SYNCHRO-SYM to meet your load CTSR. “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. The physics of our “active rotor” technology allows BEM to meet your needs better than all others with “passive rotor” technology.
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 extraordinarily included in all SYNCHRO-SYM results. In contrast, an A-EMS evolved as a disparate circuit and control system from different disciplines and as a result, most A-EMS competitors’ claims exclude the significant compounding loss, cost, and size of the required FOC controller component—artificially inflating the reported “system” performance.
Note: A fair comparison between propulsion E-Motors requires all contestants to be evaluated at the same CTSR, the same peak (burst) torque (and power) at the applied load (E-Motor SoS output shaft), and the same safe-operating burst duration (at least 10 seconds with rated active cooling, which is the real-world acceleration window). Only under these equal conditions do true comparisons emerge, such as the E-Motor peak power density, peak specific power, peak torque, system cost, and nominal efficiency. Promoting a single dramatic number, such as “peak torque,” without matching these conditions is misleading. When held to this equitable rule of physics, a passive-rotor E-Motor architecture cannot match the performance of the active-rotor SYNCHRO-SYM™—let BEM design to your CTSR, peak torque, and safe-operating-area needs.
Note: Upon customer request, BEM-CAD can a) reprogram MOTORPRINTER™ just-in-time to build SYNCHRO-SYM™ E-Motors with unmatched efficiency or power density—recognizing the reality of physics that maximizing efficiency for a given design inversely limits its peak power density, torque density, and specific power, or vice versa or b) re-design the BRTEC power module for higher torque (and current).
