可動鉄片を用いた埋込磁石構造PMモータの弱め磁束の基礎的検討 Basic Study of Flux-weakening for Interior Permanent Magnet Synchronous Motor with Moving Iron Piece
A new structure of interior permanent magnet synchronous motor with flux-shortening moving piece is described in this paper. With the help of FEM computation, the flux-weakening effect due to the moving iron piece and the operating characteristics of the motor under voltage and current constraint are obtained. By comparing the characteristics with that of the ordinary motor, it shows that the flux-weakening effect along with the rotating speed bring the motor with extensive constant output operating range as well as high torque under the limitation of voltage with proposed construction. Thus it has significant meaning in the designation of the IPM motors for used in electric vehicles.
