ABSTRACT:
A rotor for electric rotating machines has a plurality of salient poles arranged at certain intervals with each other along the outer periphery of the rotor rim. Each of the shield plates of the rotor has a plurality of reinforcing ribs arranged between adjacent salient poles and extending along the periphery of the rotor. The eddy currents flowing in the shield plates are reduced, thus reducing the eddy current losses.
