Abstract :
This paper analyzes the winding configuration and gap flux density of a 16-pole/24-slot IPM machine, and reduces the EMF harmonics and cogging torque with the methods of optimizing the surface of the rotor core and corner cut associatively by FEA. It will be seen that the method used by this paper is better than the rotor optimization method used alone. A prototype machine is manufactured and validates effectiveness of the optimization.
