ABSTRACT:
A slotless, brushless, large air gap electric motor comprises a stator having a field winding and field backiron, the field winding being composed of a plurality of successively offset polygonal shaped turns so as to provide a substantially flat winding, and a rotor disposed within the stator including a shaft with a permanent magnet mounted thereon. The field winding turns are preferably in the shape of a rectangle or a hexagonal. Also disclosed is a commutation scheme which dissipates energy stored in a section of the field winding previously energized to the section of the field winding subsequently energized; an integrated circuit for control of any motor using that commutation scheme; a winding configuration suitable for use with both an alternating and direct current power supply; and efficiency increasing magnetically permeable flux shorting elements.
