FIELD: electricity.
SUBSTANCE: invention refers to design of contactless magnetoelectric machines with electromagnetic reduction, and can be used in direct drives, in automation systems, in mechanisms with high moments on the shaft and low rotation frequencies of the shaft, as well as high-frequency electric generators and synchronous frequency converters. The proposed reduction magnetoelectric machine with pole gear-type inductor includes stator, the armature core of which is charged and has salient poles, on inner surface of which elementary teeth are made, coil m-phase armature winding, each coil of which is arranged on the corresponding salient pole of the armature, one on each pole, and rotor containing an inductor with toothed poles with equal number of elementary teeth on each pole, which are symmetrically distributed along cylindrical surface; constant magnets magnetised in tangential direction are located between toothed poles of the inductor. When performing certain relations between the number of salient poles of the armature, number of elementary teeth on salient pole of the armature, number of salient armature poles in the phase, total number of armature teeth, number of toothed poles of the inductor, total number of inductor teeth, number of elementary teeth on toothed pole of the inductor and number of phases of m-phase armature winding of reduction magnetoelectric machine with pole toothed inductor, the method is implemented.
EFFECT: providing high power and operating characteristics, high specific torque moment on the shaft and high electromagnetic reduction of rotation frequency in electric motor mode, as well as high specific power at high EMF frequencies in electric generator mode.
