Abstract
An apparatus and method of starting an electric motor (having a rotor that rotates in a given direction during steady state operation from the at rest position) generates a preliminary signal that causes the rotor to rotate in an opposite direction to that of the given direction. The method and apparatus also begin rotation of the rotor in the given direction after the rotor rotates in the opposite direction.
