Abstract
An electromechanical machine includes a stator fixed with respect to a housing structure and a rotor fixed with respect to a driven shaft. The stator includes a magnetically permeable core having a plurality of parallel winding slots containing driven windings. Coilheads are located at opposite axial ends of the magnetically permeable core where the windings turn to extend down a parallel winding slot. The motor is also equipped with an auxiliary winding arrangement to reduce capacitive coupling between the stator and rotor during operation. The auxiliary winding arrangement comprises grounded auxiliary windings located in the winding slots and the inside surface of the coilheads to interpose the driven windings and the rotor.
