Abstract :
The application of concentrated windings (CW) in interior permanent magnet (IPM) machines has been claimed to enhance high-speed performance by increasing flux-weakening capabilities of the machine. However this is at the expense of a high cogging torque, decreased winding factor as well as saliency ratio. This paper illustrates the effects of implementing well known methods to improve open circuit characteristics of the CW-IPM machine. Theoretical results are proven by the use of finite element (FE) methods and models are verified with experimental results with a prototype machine.
