Analysis of weak magnetic characteristics on novel variable main flux type outer rotor permanent magnet synchronous motor for electric vehicle drive

The air gap flux of the permanent magnet synchronous motor is constant, so the electric vehicle driven by ordinary permanent magnet synchronous motor has the disadvantages of narrow speed range and low output torque. The novel flux adjustable outer rotor permanent magnet synchronous motor by mechanical method is proposed to overcome the above shortcomings. The structure and magnetic field regulation principle of the outer rotor permanent magnet synchronous motor is introduced and analysed. The changing discipline of magnetic density distribution, flux linkage, back electromotive force, inductance and output torque are obtained based on finite element method. The change of electromagnetic characteristics at different operating speeds shows that the outer rotor permanent magnet synchronous motor has good magnetic weakening characteristics, which can promote output torque at low speed and broaden the operation range at high speed of electric vehicle.
