ABSTRACT:
A brushless electric motor includes a housing with a pair of disc-shaped end plates fixed relative to the housing in a spaced, generally parallel relationship to each other. A pair of bearings are respectively positioned in the end discs. A motor shaft is rotatably journalled in the bearings for rotation about its axis. A stator assembly is supported by the housing intermediate the end plates and through which the motor shaft passes. The stator assembly includes a plurality of individual wire-wound coils in a toroidal array around the axis of the shaft. The stator assembly has recesses in opposite faces thereof. A pair of disc-shaped rotor assemblies are respectively disposed within the recesses in the opposite faces of the stator assembly inside the end plates.
