Design and thermal assessment of a high performance electric motor for racing applications

Recently, an increasing attention in electric and hybrid vehicles is taking place. In order to raise awareness and technical knowledge on vehicles with reduced carbon footprint, several electric car competitions have been launched. Formula SAE is one of these, where talented students from different universities around the globe compete to design a fully electric racing car. This requires the development of high power density drives, with accurate electromagnetic and thermal analyses.This paper presents the design process and the thermal assessment of a high-performance electric motor intended for a FSAE racing car. The starting requirements for the electromagnetic and thermal designs are based on realistic available data from previous competitions and championship regulations.
