A rotor 10 has a structure with a rotor core 12 and rotor conductors 14, the rotor core 12 is made of a weakly magnetic substance with a high permeability and a relatively low electrical conductivity, and the rotor conductors 14 are composed of a conducting material with a low permeability and a relatively high electrical conductivity. Also, the rotor core 12 and the rotor conductors 14 are formed into a single body that has an entire surface with a smooth cylindrical shape. Furthermore, a stator 20 is composed of a plurality of stator sheets 22 laminated in the axial direction and a stator winding 24. Each stator sheet is formed with a closed circular inner ring portion 22a and an outer ring portion 22b, with slots 23 that penetrate the sheets between the ring portions, and the stator winding is housed in the slots.
