A rotor end cap for use with a rotor of a dynamoelectric machine to induce cooling air circulation, facilitate rotor balancing and enable rotor rotational position and speed sensing. The rotor end cap includes a base for attachment to a rotor of the dynamoelectric machine so that the base turns with the rotor. Further, the end cap includes a plurality of blades extending from the base in axial and radial directions with respect to the rotor for moving air to enhance cooling air circulation within the machine as the rotor turns. Still further, the end cap includes a balancing device extending from the base for altering a weight distribution around the base to balance the rotor. Yet still further, the end cap includes at least one shutter extending partially around the base for intermittently blocking passage of light as the rotor turns to enable rotational position and speed sensing of the rotor.
