Abstract:

PMaSynRM for electric vehicles uses the distributed winding. A design scheme of a 60 kW PMaSynRM used in the electric vehicle was discussed. The effect of pole-slot combination and magnet arrangement on torque capability and performance was studied by simulation method in the electromagnetic design of the distributed-winding PMaSynRM, and the irreversible demagnetization of ferrite magnets was discussed in order to draw useful conclusions that can guide.

Key words: electric vehicles ferrite, permanent magnet assisted synchronous reluctance motor (PMaSynRM), distributed winding, torque capacity, irreversible demagnetization
