Abstract
Abstract The present invention is an energy storage apparatus having a rotor and a stator. The stator includes a bobbin having a cylindrical shape and open at each end. The bobbin includes at least one fin extending longitudinally on an exterior surface of the bobbin. The bobbin also includes a phase winding longitudinally and circumferentially encircling said bobbin. The winding is separated by at least one fin. The bobbin also includes at least one cooling passage for transporting a cooling medium.
