CJ 00 CJ i> i-H o CJ O £ FIG, 25 (57) Abstract: A method and apparatus for reducing electro­ magnetic drag in an electric machine may include a lamin­ ated stator having wire slots disposed around the inner peri­ phery spaced into sectors separated by a pole iron support structure. The slots contain induction windings. A series of wound lateral pole irons may be arranged around the inner periphery of the stator, the first ends of which extend into the slots in the sectors. A support structure supports the lat­ eral pole irons by forming circular a opening concentric with the inner periphery of the stator. A rotor may be inserted into the circular opening of the lateral pole iron support structure and supported the at stator lateral pole iron ends by a support means. A plurality of rotor inserts may contain free- wheeling permanent magnet inserts spaced along an outer periphery of the rotor. The rotor may be inserted into the circular opening of the lateral pole iron support structure and the free- wheeling permanent magnet inserts may be in­ serted into cavities along the outer periphery of the rotor.
