There are several causes of rotation ripples. This paper focuses on variations of manufacturing of a stator coil and proposes a new technique called DTMM (dynamic multi-coils-motor three-phase matching) based on the conventional NSDEM (noise shaping dynamic element matching). With DTMM, all the moving elements are shuffled while a single moving element is shuffled with NSDEM.
