The curvature, parallelism, and thickness tolerances of motor magnet directly determine the uniformity of the magnetic field and the symmetry of the air gap. Deviations in precision can cause distortion of the air-gap magnetic field, leading to torque ripple, reduced efficiency, and abnormal noise. Strict control of magnetic plate dimensions and assembly positioning can prevent demagnetization in high-speed motors or vibration in new energy vehicle drive systems, ensuring high power density and
