Design and Research of Disc PMSM for Electric Wheel

Abstract

This paper studies on how to design a new kind of permanent magnet synchronous motor according to the need of electric wheel. We broaden the limits from the power density and moment of inertia, and focus on security, speed control range, start torque, overload capacity and so on. By linking mechanism, the motor is connected to wheels and drive them directly. The motor and the wheel hub also remain relatively independent. So the motor inherits the advantage of electric wheel and broadens the limits from dimension at the same time.
