Abstract
A dynamo-electric machine comprises: a shaft; a core secured to the shaft having slots formed therein extending in the axial direction; a winding composed of a wire or wires wound by a lap winding method through the slots; a commutator having commutator segments being disposed at one end of the core and secured to the shaft; and equalizing connectors electrically connecting commutator segments which should have the same electric potential; wherein one end portion of each of the equalizing connectors is connected to one of the commutator segments and the other end portion of each of the equalizing connectors passes through the slots and is connected to the other of the commutator segments.
