Abstract
An outer rotor for use with a brushless DC electric motor includes a rotor body, a shaft coupled for co-rotation with the rotor body and defining a rotational axis, a cover surrounding at least a portion of the rotor body, and a fan integrally formed with the cover as a single piece. The fan includes a plurality of blades extending radially outward of the cover and configured to induce an airflow along an exterior surface of the cover in a direction parallel with the rotational axis.
