To suppress continuation of short circuit due to induction voltage by a simple configuration.SOLUTION: A rotor shaft 40 extends in an axial direction. A rotary electric machine 30 comprises: a rotor 34 provided radially outside the rotor shaft 40; and a stator 38 provided radially outside the rotor 34. Rolling bearings 42, 44 are interposed between the rotor shaft 40 and the rotor 34 to allow relative rotation of the rotor shaft 40 and the rotor 34. A lock magnet 60 is fixed to the rotor shaft 40. A lock pin 50 switches coupling and uncoupling between the rotor 34 and the lock magnet 60 by moving in an axial direction by excitation of the lock magnet 60.SELECTED DRAWING: Figure 3
【課題】簡易な構成で、誘起電圧による短絡継続を抑制する。【解決手段】回転子軸40は、軸方向に延びている。回転電機30は、回転子軸40の径方向外側に設けられた回転子34と、回転子34の径方向外側に設けられた固定子38と、を有している。転がり軸受42,44は、回転子軸40と回転子34との間に介在して回転子軸40と回転子34とを相対回転可能にする。鎖錠電磁石60は、回転子軸40に固定されている。ロックピン50は、鎖錠電磁石60の励磁により軸方向に移動することで、回転子34と鎖錠電磁石60との連結と非連結とを切り換える。【選択図】図3
