ABSTRACT:
A low profile electric motor has a disk-shape armature with front and rear faces. Each face has a plurality of armature windings, the turns of each winding extending across each face from one point on the periphery of the armature inwardly across the face to a point adjacent the center of the face and outwardly to another point on the periphery. The novel arrangement of the windings maximizes the number of turns that are cut by the magnetic flux generated by the motor field magnetics, and thus increases the torque produced by the motor. The rotor is not penetrated by the shaft, in one embodiment.
