Design of an outer-rotor-type permanent magnet motor for electric scooter propulsion systems

This paper proposes an outer-rotor-type permanent magnet motor for electric scooter propulsion systems. The designed motor is integrated into the wheel rim on the tire and meets the specifications of the electric scooter. The simulation using non-linear finite element analysis (FEA) method results match experimental data obtained from the prototype 20-poles motor for electric scooter propulsion systems. The overall efficiency achieved 87% at rated speed. The detailed test results have been presented.
