Challenges in the design of a 100 kw induction motor for a PHEV application

This paper summarizes some design challenges encountered in the development of a high speed induction motor/generator for a plug-in hybrid electric vehicle (PHEV). The traction system motor/generator was developed for integration into a high performance full-sized passenger car being developed by a major automotive manufacturer. The paper summarizes the traction motor performance requirements and presents the electromagnetic, mechanical and thermal design issues of the high speed 100 kW peak power induction machine.
