Abstract: A driving motor for an electric vehicle includes a rotor having a field coil wound thereon and a stator having an armature coil wound thereon. The driving motor includes a motor control unit to perform temperature based control between the stator and the rotor based on which one has a higher temperature than the other, in order reduce a current value to the one having the higher temperature than the other.

Abstract: A motor includes a plurality of tooth bodies extending from a rotor core. A pole shoe extends from an end of at least one tooth body at opposite sides where both sides of the pole shoe have a curved outer part opposite to each other and asymmetric to each other in that a radius of curvature of the curved outer part of the one side of the pole shoe that is in a rotational direction of the rotor has a smaller radius than a radius of curvature of the other side of the pole shoe that is not in the rotational direction of the rotor.
