Abstract
According to various aspects, exemplary embodiments of an electric motor are provided herein. In one embodiment of this disclosure, an electric motor includes a rotor, at least one end of the rotor includes at least one blade and at least one array of micro-features, wherein heat generated by the rotor is dissipated by the at least one blade and the at least one array of micro-features. In another embodiment, a method of manufacturing an electric motor having a rotor, the method comprising machining a piece of conductive material to create micro-features on at least one end of the conductive material; and inserting the conductive material into the rotor.
