NONREVERSIBLE STEPPING MOTOR Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: nonreversible stepping motor is designed for discrete electric drives. Magnetic core 2 with rods and pole pieces 4 between which magnets 5 with pole pieces 6 are placed is anchored on frame parts 1. Rectangular cuts-out for interaction with registering cuts-out in pole pieces 6 are made between teeth of rotor. Each of pole pieces 6 of magnets 5 is manufactured integral with cover of one of bearings 9. Symmetry plane of rotor is matched with that of magnetic core 2. EFFECT: enhanced reliability and precision of stepping action, simplified design. 10 dwg
