FIELD: electrical engineering. SUBSTANCE: inductor-reactive stepping electric motor is designed for discrete electric drives. Nonmagnetic frame 1 carries magnetic core 2 with pole pieces and magnet 5 with pole piece 13 mounted with outer radial gap to pole pieces of magnetic core 2. Pole piece 6 of magnet 5 forms inner radial gap with tips of teeth of rotor. With energizing of winding torque emerges under which action rotor goes to position in which it remains after ending of current pulse. With coming of pulse of opposite polarity rotor executes step of π/2. EFFECT: ensured reliability of stepped rotation. 10 dwg
