摘要
The sixth order torque ripple harmonic in induction motors under field oriented control with voltage space phasor modulation is investigated by means of a simulation model. It is shown that the main reason for its appearance lies in the PWM modulation. Measurements on a 220 kW asynchronous drive confirm the simulation results. A compensation strategy is proposed.
