Abstract
A motor-generator apparatus has a stator and a rotor in a cylindrical arrangement about a central longitudinal axis. The stator has a static circular magnetic surface spaced apart from, a static circular electromagnetic surface. The rotor has a cylindrical arrangement of radially oriented laminations positioned proximal to, and between the static circular magnetic, and the static circular electromagnetic surfaces. The rotor is supported for rotation relative to the stator. A circular arrangement of electromagnets are electrically interconnected for carrying an electrical current for energizing the circular electromagnetic surface which is discontinuous with a plurality of portions gapped apart.
