EV category of the Student Formula Japan Competition will be an official event in 2013. In order to optimize the regulations of the category, we have developed an EV based on a vehicle driven by an engine for the student formula. At first, our prototype motor was applied to its traction motor and the test run was performed, and we developed an Interior Permanent Magnet Synchronous Motor (IPMSM) suitable for the formula by analyzing the test data. Furthermore, we developed a motor which achieved higher power density and correspondence to the regulation. This paper introduces the developed IPMSM.
