Magnetization of Electric Motors in New Energy Vehicles: Why Are the Precision Requirements Far Higher Than Those for Conventional Motors?

August 10, 2026 324

The requirements for magnetization accuracy in new energy vehicle drive motors are 3 to 5 times higher than those for traditional industrial motors. This paper analyzes the necessity of high-precision magnetization from three perspectives—motor efficiency, NVH control, and thermal management reliability—and discusses the design approach for achieving ±1% flux consistency.
