Abstract

The balanced commutator method of computing the reference currents for current tracking feedback is presented. For a given switch reluctance (SR) motor, the commutator reduces the peaks and the rate of change of the reference currents. This allows accurate current tracking, and therefore minimum torque ripple, over a wider range of operating speeds. Reference current waveshapes for two different SR motors, and the resulting torque ripples, are compared

用于三相开关磁阻电动机的平衡换向器,以最小化转矩波动
提出了一种计算电流跟踪反馈参考电流的平衡整流子方法。对于给定的开关磁阻(SR)电机,换向器降低了参考电流的峰值和变化率。这允许精确的电流跟踪,因此最小的转矩脉动,在更宽的操作速度范围内。比较了两种不同SR电机的参考电流波形,以及由此产生的转矩波纹
