WIRE WINDING METHOD FOR STEPPING MOTOR

PROBLEM TO BE SOLVED: To improve the space factor of windings wound around each stator magnetic pole, and prevent short circuits between two windings wound around the same magnetic pole. SOLUTION: Wires in an A phase and a reverse A phase and in a B phase and a reverse B phase are wound around each magnetic pole on the stator 10 of a stepping motor M. At this time first magnetic poles P1, P3, P5, P7, around which wires W1, W3, W5, W7 in the A phase and in the negative A phase are wound, and second magnetic poles P2, P4, P6, P8 around which wires W2, W4, W6, W8 in the B phase and in the reverse B phase are wound are placed alternately in the stator 10. In each set of two oppositely faced magnetic poles, first and second magnetic poles, the wires in the A phase and in the B phase are wound inside one of the magnetic poles and the wires in negative the A phase and in the reverse B phase are wound outside the one magnetic pole. The wires in the negative A phase and in the reverse B phase are wound inside the other of the magnetic poles, and the wires in the A phase and in the B phase are wound outside the other magnetic pole.
