Abstract:
 Abstract:The current of permanent magnet synchronous motor(PMSM)contains a lot of harmonic cur-
rents,resulting in the motor current waveform distortion. In order to solve this problem,a novel suppres-
lion method based on synchronous rotating coordinate transformation was proposed. Based on the estab-
lished model of PMSM,the adverse impact caused by harmonics was analyzed. Through rotating coordi-
nate transformation and low-pass filter,the fifth and seventh harmonic currents were extracted and con-
trolled by PI regulator. Simulations and experiments with a 4-kW magnetic suspension PMSM were car-
rigid out. The results verify that the method based on coordinate transformation can suppress the harmonic
currents caused by different reasons. The proposed method has the advantage of easy mathematical com-
putation and simple implementation.
