FIELD: electricity.
SUBSTANCE: invention relates to the field of electric engineering and designs of contactless reducer electromagnetic machines with electromagnet reduction, intended for use as motor - wheels, motor - drums, direct drives in electrical appliances (electric meat grinders, washing machines, etc), electric drives of concrete mixers, weight-lifting mechanisms, belt conveyors, pumps for pumping of fluids, mechanisms with high torque on shaft and low frequencies of shaft rotation, and also as high-frequency electric generators. Proposed contactless reducer electromagnet machine comprises stator with explicit poles, on inner surface of which there are elementary cogs, m-phased focused anchor winding of which consists of coils, each coil covering an appropriate anchor pole, and winding-free ferromagnetic rotor, comprising two inductor cores displaced relative to each other in tangential direction by half of gear division, with toroid permanent magnet magnetised in axial direction and installed between cores of inductor, to develop magnetic flow of excitation. At the same time certain ratios are maintained between number of anchor poles, number of elementary teeth on anchor pole, number of anchor poles in phase, common number of anchor teeth, number of teeth on each inductor core and number of phases of anchor winding of contactless reducer electromagnetic machine.
EFFECT: high power and operational indices, high specific rotary torque on shaft and high electromagnetic reduction of rotation frequency in mode of electric motor, high specific capacity at high frequencies of electromotive force in mode of electric generator.
