Abstract
An electric motor includes a frame, a stator disposed in the frame, a rotor disposed in the frame, and a cooling unit configured to perform a cooling operation by supplying a cooling fluid into the frame. Under this configuration, a cooling function may be enhanced, and a high output density and high efficiency may be implemented.
