摘要
Abstract
This study focuses on a permanent magnet synchronous motor(PMSM)with a rated power of 85 kW and a rated speed of 330 r/min.The relationship between cogging torque and current harmonics in PMSM is derived,and the mechanism by which harmonic injection affects cogging torque is analyzed.Through electromagnetic field modeling and simulation,the influence of current harmonics with different frequencies,phases,and amplitudes on cogging torque is examined.The results indicate that by adjusting the amplitude and phase parameters of the harmonic current,it is possible to suppress the amplitude of cogging torque.关键词
