Influence of winding configurations on torque ripple production in high phase order induction machines.

M. Tech. Electrical Engineering. / Discusses the placement of windings in the slots of high phase order induction machines (HPOIMs) leads to a stepped-like waveform of stator (rotor) MMFs which exhibit space harmonics as well as the fundamental wave. The interaction of air-gap field components, which have the same pole number but rotate at different speeds, produce the torque ripple whose magnitude depends on the product of the magnitude of the two interacting fields. The frequency of the torque ripples also depends on the difference between the speeds of these two fields. A winding configuration or a combination of different configurations that reduces some air-gap components has the edge in terms of mitigating the ripple torque contents.
