BEST ELECTRIC MACHINE → BOTTOM LINE UP FRONT

Our flagship product, SYNCHRO-SYM™, is the magnet-free, drop-in replacement for today’s variable-speed electric motor-generator systems (E-Motor)—matchlessly delivering 2× to 8× the performance-per-$ and torque at the same voltage and frequency, eliminating permanent magnetic cogging or drag, significantly reducing copper and electrical steel per KW of rating, and realistically providing tunable, maintenance-free, low wear, electromagnetic gearing and braking. Unlike conventional E-Motors—limited by the circuit and control asymmetry of an Active Stator + 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)—SYNCHRO-SYM™ is free from these constraints. Scaling across electric vehicle (EV), wind, aerospace, and commercial applications, only SYNCHRO-SYM™ provides:

1. Active Stator + Active Rotor Symmetry — both halves independently deliver working power to the electromechanical conversion, grounded in physics—not marketing spin.
2. Brushless Real Time Emulation Control (BRTEC™) — quantum level stabilization with a novel brushless, symmetrically bidirectional, inherent soft switching, 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.
3. Magnet-Free Operation — eliminates rare-earth PM (RE-PM) dependence, avoiding alarming cost, environmental harm, and geopolitical risk.
4. Just-In-Time Additive Manufacturing — enables rapid, scalable, and cost-effective production with MOTORPRINTER™, the only electric motor 3D Printer Method, and BEM-CAD™, the only CAD with SYNCHRO-SYM extension and cross-analysis.
5. Future-Ready Architecture — most compatible symmetric circuit and control technology for retrofitting next-generation E-Motors, including superconductors.
6. Expert-Driven Culture — engineering excellence, customer focus, and principled innovation.

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” 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 controlled by an estimating 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 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, lubricated gears to reduce costly rare-earth permanent magnets (RE-PM) or achieve reasonable torque—all from different technical disciplines without shared understanding—often from different manufacturing sources—all with so-called “integration” amounting to little more than adjacent mounting. As a result, the compounded losses, costs, and size of these essential components are often overlooked in the real-world “system” 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, integral, Brushless Real-Time Emulation Control (BRTEC)—allows both rotor and stator to independently and stably contribute similar 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 passive-rotor A-EMS E-Motor with similar design specifications and packaging.

• Our patented SYNCHRO‑SYM™ is a complete integral system—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™)—quantum level stabilization with inherent symmetrically bidirectional, soft switch, direct AC-to-AC power conversion at half the current rating; no bulky, costly DC link stage—inherently providing full rotor and stator metrics 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.

A BEM E-Motor product purchase—provides the world’s first and only practical S-EMS product purchase.

• 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! Accordingly, over a half-century of classical laboratory research already validated that the performance-to-price and torque of any A-EMS E-Motor package will be multiplied by 2× to 8× if retrofitted with the S-EMS circuit and control technology—slashing losses, eliminating the need for rare-earth magnets, significantly reducing strategic materials per KW, and realistically enabling maintenance-free, tunable, gearless electromagnetic transmission & electromagnetic braking. Note: Never realizing the practical BRTEC invention of today’s SYNCHRO‑SYM™, the higher performing S-EMS was sidelined by the timely invention of the practical high-energy product RE-PM (circa 1980) for the A-EMS, despite the then-unforeseen environmental and geopolitical consequences of their widespread adoption.

• Only SYNCHRO‑SYM™ is a drop-in replacement to any A-EMS E-Motor but uniquely with more power, more torque, more efficiency, and no rare-earth permanent magnets—including in-wheel E-Motors—never confuse SYNCHRO‑SYM™ with the so-called wound-rotor doubly-fed induction E-Motors, the so-called brushless doubly-fed E-Motors with unlike pole-pairs, or the so-called symmetric E-Motor with dual-adjacent-passive-rotor symmetry (e.g., DeepDrive)—examples of an A-EMS. 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 an integral active rotor electric motor-generator circuit and control technology—all other so-called software E-Motors are built with 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 other advanced packaging techniques, such as superconductors that establish air-gap flux density beyond the supporting limits of core material—today necessitating a costly, complicated, exotic, bulky, lossy system of extreme packaging techniques, inefficient cryogenic refrigeration and hydraulics that is impractical for most applications.

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 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™ offers significantly higher-performance and an ethically sound alternative to the RE-PM-based A-EMS E-Motor—long regarded by practitioners as the best, yet unethically monopolized by geopolitical adversaries and burdened with alarming environmental, labor, supply chain, and geopolitical risks. By eliminating RE-PMs from E-Motors while improving performance, SYNCHRO‑SYM™ redirects a majority of these scarce materials to be more strategic applications and mitigates the sustainability supply of global mineable reserves to meet the projected surge in high performance RE-PM E-Motor demand.

• 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 RE-PM E-Motors, switching to SYNCHRO-SYM™ delivers a step-change in efficiency, power density, and cost, successfully eliminating rare-earth permanent magnets (RE-PMs) with their alarming environmental, supply-chain, and geopolitical consequences.

• 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, 250kW 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, despite its best-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 280KW (continuous duty) or 560KW (peak duty/gearless 2675Nm torque) @ 2000 RPM constant-torque-speed-range Axial-Flux SYNCHRO-SYM E-Motor is the unmatched rival to Koenigsegg’s Quark E-Motor—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 and constant-torque speed range (CTSR) of 2000 RPM—speeds beyond CTSR enter the constant-power-speed-range (CPSR) (vs. Koenigsegg’s performance skewed 4000 RPM CTSR)
• Peak System Efficiency (@CTSR): 98%
• Cost per KW at peak power: see E-Motor Early-Access (vs. Koenigsegg: N/A)

Note: August 2025 material pricing.

Note: Loss, Size, Weight, and Cost of our integral BRTEC controller extraordinarily included in all results. In contrast, most A-EMS competitors’ claims exclude the significant loss, cost, and size of the required FOC controller component—artificially inflating the reported “system” performance.

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 physics reality 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).

For our customers with a tamer application, BEM-CAD designed our “novel” Brushless 140KW (continuous duty) or 280KW (peak duty/gearless 2675Nm torque) @ 1000 RPM constant-torque-speed-range Axial-Flux SYNCHRO-SYM E-Motor is also an unmatched rival to Koenigsegg’s Quark E-Motor and available for purchase with the world’s lowest-cost per unit of power:
