小型EV用アキシャルギャップ型スイッチトリラクタンスモータの損失に関する実験的考察

抄録

  A switched reluctance motor (SRM) has a simple and robust structure since it consists of only stator cores, rotor cores and windings wounded around the stator poles. In previous papers, axial-flux-type switched reluctance motors (AFSRMs) were prototyped and installed into the rear wheels of a compact electric vehicle (EV). Driving tests were conducted with success. However, there was a difference between the losses calculated by electromagnetic field analysis and those measured from the prototype AFSRM. In this paper, the causes of the difference are investigated in experiments.
