Single-phase step micromotor

Реферат: SINGLE-PHASE STEP MICROMOTOR Abstract of the Disclosure A single-phase step micromotor comprising a stator having a pair of pole pieces facing each other by cylindri-cal surfaces thereof. Interposed between the stator pole pieces is a double-pole rotor, while arranged between the stator and rotor is a rotor fixing means in the form of a ring the thickness of which is less than that of the stator pole pieces, the inner diameter of the ring varying along the angular coordinate of the stator. The invention can be applied to advantage in horology, such as for the manufacture of electronic/mechanical wrist-watches with dial display.
