Amid global rare-earth shortages, BEM launches SYNCHRO-SYM™, a proven magnet-free E-Motor that doubles performance-to-price and is open for early-adopter orders
BEDFORD, MA, UNITED STATES, August 20, 2025 /EINPresswire.com/ — Best Electric Machine (BEM) today announced availability of SYNCHRO-SYM™, the only E-Motor system that eliminates rare-earth permanent magnets (RE-PMs) while more than doubling performance-to-price in the same package.
Recent global disruptions in RE-PM supply—already impacting automakers in the U.S., Europe, India, and Japan—underscore the urgent need for E-Motor alternatives.
By contrast, SYNCHRO-SYM E-Motor replaces passive rotors of permanent magnets, slip-induction windings, reluctance saliencies, or DC field windings with a brushless, symmetric, dual-active design that physics dictates will inherently double the constant torque speed range for a given frequency and voltage. This results in more than twice the power density, half the loss, lower cost, and no dependence on geopolitically concentrated RE-PMs. SYNCHRO-SYM also avoids common issues like cogging, high inductive reactance, and core saturation—delivering peak torque more than eight times nominal without compromise.
BEM’s proprietary MOTORPRINTER™ 3D printing process ensures rapid, secure, and scalable manufacturing of axial-flux designs. Together with its brushless and sensorless Real-Time Emulation Control (BRTEC), SYNCHRO-SYM provides direct AC-to-AC conversion while controlling only half the current—making it more efficient and reliable than traditional inverter-based controllers—reducing the per kW cost of WBG semiconductors.
BEM invites early-adopter partners in EV, wind turbine, and aerospace markets to secure SYNCHRO-SYM units at competitive pricing—accelerating deployment of this next-generation, magnet-free technology and supporting its path to broader market readiness.
