ORBITAL GEAR MOTOR Russian patent published in 1997 - IPC

FIELD: dual-speed electric drives. SUBSTANCE: gear motor has wound stator, rotors 14 coupled with orbital gearbox whose satellite teeth 31 are in mesh with teeth of its central gear 20 mounted in bearings and having brake. Rotors 14 are mounted on same shaft as satellites and have electromagnetic brake with disk mounted for rotation about longitudinal axis and enabling relative locking of rotors while providing for rotation of such composite rotor relative to output shaft axis. In this way, dual-speed operation is provided. EFFECT: improved design. 3 dwg
