Zusammenfassung:	A vent plate for a rotor of a motor core includes a hub, a plurality of spokes extending from the hub and a plurality of coffin portions each having a coffin bore extending therethrough and at least one of which is connected wi th a spoke. The coffin portions may each be radially spaced from, and circumferentially spaced about the hub and wherein each coffin portion comprises an outer radial end, and a connecting ring which extends about the periphery of the coffin portions. The connecting ring may engage each outer radial end. In another embodiment of the present invention, a method of making a rotor for an electric motor is also presented.
