A Comparison of Three Phase and Five Phase BLDC Motor

Kiran George, Sija Gopinathan, Shinoy K.S.

This paper presents an investigation into the advantage of polyphase machine over conventional three phase machine. It is also shown by finite-element analyses that, by appropriately defining the pole–arc to pole–pitch ratio, fractional slot winding and selecting proper slot per pole combination the cogging torque can be minimized. The analysis is carried out for a three phase and five phase permanent magnet brushless direct current motor.
