外转子永磁同步电机的噪声抑制与齿槽转矩优化

This study proposes a multiphysics coupling optimization methodology to mitigate electromagnetic noise and cogging torque in external rotor permanent magnet synchronous motors. A slot-pole interaction analysis model is developed, incorporating nonlinear magnetic permeability modulation effects, to elucidate the spatiotemporal distribution characteristics of electromagnetic forces and their resonan...
