摘要

本文比较了准方波电流和正弦波电流激励下梯形反电动势和正弦波反电动势对永磁电机转矩脉动的影响。该分析是针对速度范围要求从10rpm到500rpm的应用程序进行的。仿真结果表明，在与反电动势同相的正弦电流激励下，用正弦反电动势驱动永磁电机时，转矩脉动最小，效率最高。

Comparison of electromagnetic torque ripple in square wave and sine wave permanent magnet motor drives

This paper presents the comparison of torque ripple in a permanent magnet motor drive with trapezoidal and sine wave back EMFs, excited by quasi square and sinusoidal currents. The analysis is done for an application where the speed range requirement spans from 10 RPM to 500 RPM. The simulation results show that the permanent magnet motor drive with sinusoidal back EMF excited by a sinusoidal current, which is in phase with the back EMF, gives minimum torque ripple and maximum efficiency.
