Abstract
The present disclosure includes: a holding ring fitted to a rotor and holding a rotor coil of the rotor; and an interpolar jumper wire electrically connecting field poles of the rotor to each other, the interpolar jumper wire being composed of a flexible lead formed by stacking electrically conductive metal plates and a metal wire connected to the flexible lead. In a case where the flexible lead is divided, in terms of positions in a radial direction of the metal plates thereof, at half the number of all the stacked metal plates, an average value of plate thicknesses of metal plates that are disposed on an inner layer side is set to be smaller than an average value of plate thicknesses of metal plates that are disposed on an outer layer side.
