Abstract :
The wheel motor directly drives the vehicle, so its structural and electromagnetic design has some difficulties, and it will affect the performance improvement of the motor. Based on the exterior-rotor radial-flux permanent magnet (PM) wheel motor, we have done relative study on improving the motor performance from four aspects: magnetization direction and pole number; no-load air-gap flux density; no-load electromagnetic force (EMF); and flux insulation. Theoretical analysis, design data, and simulation results are given in this paper, and we have developed a first-round prototype LQI based on them
