Abstract

The paper studies the optimized design problems of permanent magnetic synchronous machine (PMSM) for low-speed and high-torque (LSHT) drive systems, and indicates that the key points of eliminating PMSM torque ripples at low frequency make the inner potential waveform sinusoidal. Through theoretic analysis and optimized design of main factors about influencing on PMSM potential sine waveform by means of uniting traditional design methods and modern intelligent optimization (genetic algorithm), a real PMSM is designed and the experimental results are given in the paper.
