SYNCHRONOUS MOTOR WITH ELECTROMAGNETIC SPEED REDUCTION Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: synchronous motor incorporating electromagnetic speed reduction provision has stator with poles provided with teeth on their internal surface, m-phase winding built up of 2mp coils (p is number of pole pairs) mounted on poles, switching device, and non-wound toothed rotor; pole shaders made of high-conductance nonmagnetic material are provided over periphery of toothed rotor and arranged on rotor teeth so that at any turn of toothed rotor and arranged on rotor teeth so that at any turn of rotor at least one pole shader occurs under each stator pole. EFFECT: improved design. 1 dwg
