High-Performance Electric Motor for Motor Sport Application

The objective of this paper is to introduce a new high performance electric motor for a high speed and torque motor sport application. A compact radial flux machine, with double layer concentrated winding and interior permanent magnets has been designed to achieve high torque with a low weight. The motor is made with 18 copper coils, 6 per phase, pre-wound and placed in the slots, which are directly cooled by forced oil. The motor is also equipped with a shaft spiral groove cooling system for magnet temperature control.
