Arc Motor Magnet

BMAG Arc Motor Magnets are engineered specifically to maximize the efficiency and torque density of high-performance electric motors. Designed to fit seamlessly onto rotors or inside stators, these magnets feature a precision-ground curvature that minimizes the air gap between the rotating and stationary components. By optimizing this magnetic circuit, BMAG arc magnets significantly reduce flux leakage and enhance the overall electromotive force (EMF) of the motor.

We utilize advanced sintering techniques to ensure high magnetic consistency across the entire arc surface. These magnets are available in a wide range of operational grades, including high-temperature series (M, H, SH, UH, EH, AH) capable of withstanding operating temperatures up to 220°C without irreversible demagnetization. The precise radius grinding allows for tighter mechanical tolerances, which is critical for reducing noise and vibration in high-speed motor assemblies. Whether you are designing for high RPM or high torque, these arc magnets provide the magnetic muscle required for modern propulsion systems.
