ELECTRIC MOTOR Russian patent published in 2000 - IPC

FIELD: electrical engineering, source of power for electric drive. SUBSTANCE: stator of given electric motor carries electromagnets which interact with permanent magnets mounted on rotor to ensure creation of torque by the latter. Power supply of electromagnets is switched over from electron inverter. Permanent magnets are placed uniformly over periphery of rotor with alternating polarity with angular distance between axes of adjacent magnets α. Electromagnets are put on stator in opposition to permanent magnets in two groups as minimum so that angular distance between axes of any two electromagnets in each group is multiple of angular distance α. Groups of electromagnets are located on arc one relative to another. Transducer of angle of turn of rotor is mounted on stator. EFFECT: simplified design, enhanced efficiency and facilitated operational process. 2 cl 3 dwg
