DRIVING DEVICE FOR MOVABLE MEANS Russian patent published in 1997 - IPC

Abstract RU 2074761 C1

FIELD: electrical engineering; drives. SUBSTANCE: device has permanent magnets, cores with coils, rotor angular position pickups. Rotor is made in form of concentrically arranged envelopes and is connected with rim. Permanent magnets are installed on envelopes, one opposite to the other, with opposite polarity. Permanent magnets are installed on each envelope with alternation of their polarities Stator installed between permanent magnets carries coils with cores. EFFECT: possibility of designing low speed (20-80 rpm) direct-drive electric motor with efficiency up to 80%. 2 cl, 4 dwg
