Abstract
<div class="section abstract"><div class="htmlview paragraph">This paper discusses on the reduction techniques adopted to reduce torque ripple
in an electric machine, which in turn reduces the noise generated within
electric machine during driving condition. Source-based noise reduction
techniques such as the impact of slot-opening width, use of notches, use of
wedges, and its combination are explained with specific design tips. Simulation
results show that use of wedges results in 7% reduction in torque ripple when
compared with other configurations. In addition to the torque ripple reduction,
it also reduces overall system torque. Therefore, additional methods are
discussed to increase the system torque and reduce torque ripple by 6%.</div></div>
