Abstract
Permanent-magnet motors are suitable choice for special applications such as aircrafts, marine, and electric vehicles Because of the fault tolerance and high power density capability. In this paper, an analytical design of a five-phase permanent-magnet motor is done and the advantages of multi phase motor over three phase motor are studied. Next Finite-element method is applied to verify and validate different machine designs. Finally thermal analysis of the designed machines is done. The results are shown multi phase motor has lower cogging torque and operation temperature, higher electromagnetic torque and back-emf in comparison with three phase motor.
