发明名称 ASYNCHRONOUS ELECTRIC MOTOR WITH CONTINUOUS CONTROL OF ROTATION FREQUENCY
摘要 FIELD: double- rotation electric drives. SUBSTANCE: device has primary electric motor which is equipped with rotating stator 4 and rotor 2. One shaft of primary electric motor is connected to load, another shaft 1 is connected to additional electric motor 8 through transmission gear. Transmission gear is designed as stationary rotor 3, which is mounted on same shaft as rotor of main electric motor. Additional electric motor 8 is mounted on carriage 9 which is equipped with driving screw 10. Carriage guide is parallel to shaft of additional electric motor. Driving screw provides movement of additional electric motor 8 to left side. Rotor 2 partially extends over effective magnetic field of stator 4 and is replaced with stationary rotor 3. Stator 4 starts its rotation in direction which is reverse to rotation of rotor 2, which runs in generation mode. Moments of its rotation increases upon increase of their interaction area. EFFECT: flexible device which adapts to operation mode, controls electric motor rotation, provides decreased losses, simplified design, compatibility of mechanical characteristics to current needs. 1 dwg
