This paper describes the development of an in-wheel Coreless Permanent Magnet Synchronous motor designed and built for the participation of the Aero@UBI team in Shell Eco-Marathon competition where a low power and highly efficient motor was needed. The design of the motor for this competition is presented and the adopted concepts explained. The conjunction of the concepts embedded in the design made this motor one of a kind. The use of Litz wire and a single wave winding turn allow the possibility to configure the motor’s constant. The model used in the motor’s design is presented. The motor was built, and the experimental tests data are given for the motor. The motor was tested with two different controllers and the results show the high efficiency of the presented motor.
