Measurement of torque ripple in PM brushless motors

Measurement of torque ripple in PM brushless motors

In order to resolve the torque ripple of the PM brushless DC motor, two methods of testing torque ripple are developed. One is a balanced direct testing method and the other is a current indirect testing method. The measurement errors are analyzed. The experimental results indicate that the two test...

Zusammenfassung:In order to resolve the torque ripple of the PM brushless DC motor, two methods of testing torque ripple are developed. One is a balanced direct testing method and the other is a current indirect testing method. The measurement errors are analyzed. The experimental results indicate that the two testing methods are agreement.
