Abstract
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.
