(MENAFN- EIN Presswire) EINPresswire/ -- Best Electric Machine (BEM) today announced new performance findings demonstrating that its patented SYNCHRO-SYMTM symmetric motor architecture can retrofit into conventional electric-motor system packaging geometries while delivering approximately 50% higher performance-to-price than state-of-the-art permanent-magnet and reluctance drive systems.

Unlike today's electric-motor systems relying on asymmetric passive-rotor architectures - including permanent magnets, reluctance, induction, or field excited designs - paired with external derivatives of field-oriented control (FOC), which rely on packaging optimizations and incremental magnetic material improvements - SYNCHRO-SYM introduces a fundamentally different approach: a symmetric electromagnetic circuit and control with an active-rotor architecture, unified with Brushless Real-Time Emulation Control (BRTECTM).

This architecture doubles usable electromagnetic contribution by enabling both stator and rotor to independently participate in real work conversion, overcoming the inherent limitations of passive-rotor machine systems, including magnetic saturation.
“Industry has spent decades admirably refining packaging geometries and materials,” said Fred Klatt, CTO of Best Electric Machine.“SYNCHRO-SYM changes the physics inside the same geometry - delivering higher power density, wider speed range, less material, and lower cost-per-kilowatt without rare-earth magnets.”

Key Advantages of SYNCHRO-SYMTM
.~50% better performance-to-price in like-for-like form factors
.No rare-earth permanent magnets - mitigating supply risk and cost volatility
.Active rotor power contribution - doubling utilization vs. today's passive rotor machine systems
.2× nominal power - with the same package geometry, port voltage, and excitation frequency
.Up to 8× peak-torque capability - sustained without magnetic saturation
.Lower controller cost & loss via direct AC-to-AC BRTEC architecture
.Reprogrammable 3D-printing motor manufacturing (MOTORPRINTERTM) for rapid scale and domestic production

SYNCHRO-SYM maintains compatibility with existing radial-flux, axial-flux, in-wheel, and direct-drive packaging formats, allowing vehicle OEMs to adopt the architecture without platform redesign - and, with unified BRTEC, simplified electrified-platform integration.

Industry Relevance
As EV manufacturers face rare-earth supply constraints, cost pressures, and demands for higher drive-unit density and efficiency, SYNCHRO-SYM offers a novel physics-based alternative that achieves superior torque-speed characteristics, 2× constant-torque-speed range, and high efficiency across load conditions. This comes at a pivotal moment for the EV sector, where drivetrain efficiency, supply chain resilience, and manufacturing scalability are priority challenges.

SYNCHRO-SYM technology has been validated through prototype development, patents, and comparative electromagnetic analysis using industry-standard packaging. BEM is now preparing early-adopter deployments as part of its commercialization program, aligned with increasing OEM interest in rare-earth-free motor solutions.
