    摘要: In an electric rotating machine, for reducing losses that occur in clamping plates and their shield, the electric rotating machine includes a rotor formed with field winding wound around a rotor core, a stator placed opposite to the rotor at a predetermined space and formed with stator winding wound around a stator core formed by stacking multiple magnetic steel sheets in the axial direction, clamping plates clamping and retaining the stator core from both axial end parts thereof in the stacking direction of the magnetic steel sheets, and a magnetic shield placed around the clamping plates to shield flux leakage flowing into the clamping plates, and the magnetic shield is formed of a cylinder of stacked steel sheets stacked in a form of a cylinder about the rotor shaft and powder magnetic core segments and powder magnetic core segments having portions which are stuck to the cylinder of stacked steel sheets on the stacking cross section, and arranged to cover side surfaces and an inner surface of radial direction of the clamping plates.
