Disc-type motor characterized by increased efficiency. The motor has two parallel spaced stator members (30, 32) each having a flat circular shape and an even plurality of pre-segmented permanent-magnet poles (34) in a circular array thereon, illustratively eight in number. The facing poles of the stator members have opposite polarities. The motor includes a disc rotor (28) made of a non-conducting material rotatably mounted between the two stator members. Conducting wires are wound to form a number of coils (29) in a circular array on each face of the rotor. The number of coils on each rotor face is greater than the number of poles on each stator member, and each coil (29) occupies an arc sector area smaller than the area of each stator pole (34). The coils (29) arrayed on one face of the rotor (28) are angularly offset from the coils on the other face of the rotor. The includes a commutator (44) connected to the rotor (28) which has a number of segments corresponding to the coils of the rotor.@00 |
