ABSTRACT:
A rotor core of an electric rotary machine is provided with a number of slots opening toward the outer peripheral surface of the core and teeth formed between the slots. At the sides of the rotor core are mounted spidery end plates having notches opposing the slots and projections opposing the teeth. That end surface of the projection which is remote from the rotor core is formed to extend farther from the end surface of the rotor core as it becomes distant from the axis of the rotor core. The rotor winding is wound about the rotor core and spidery end plates to be buried in the slots and notches, the bottom of the notch being higher than the laminate slot, so that the slot liner is not distorted during winding operations.
