The performance of fault-tolerant modular PM machines depends on the proper selection of the pole and slot numbers which results in negligible coupling between phases. The preferred slot and pole number combinations eliminate the effect of low order harmonics in the stator MMF and thereby the vibration and stray loss are reduced. In this paper, three machines, with an external rotor design and identical machine dimensions, are designed with different slots per phase per pole (SPP) ratios. A… CONTINUE READING
