FIELD: electricity.
SUBSTANCE: invention is related to the field of electric engineering, in particular to slow-speed high-torque electric motors, electric drives and generators, is related to peculiar features of design in contactless electromagnetic electric machines with electromagnetic reduction and may be used in automatics systems, as motorised wheels, motorised drums, starter-generators, electric steering booster, direct drives in household appliances, electric drives of concrete mixers, weight-lifting mechanisms, belt conveyors, pumps for pumping of liquids, mechanisms with high torques on shaft and low frequencies of its rotation, and also as wind power generators, hydrogenerators, high-frequency electric generators and synchronous generators of frequency converters. Proposed contactless reducer electromagnetic machine with multipack inductor comprises stator, anchor core of which is assembled from insulated sheets of electrical steel with high magnetic permeability and has explicitly expressed poles, on internal surface of which there are elementary teeth arranged, coil m - phase winding of anchor, each coil of which is placed on according explicitly expressed pole of anchor, and winding-free ferromagnetic rotor, comprising inductor with odd and even teethed cores with identical number of teeth on each core, odd and even teethed cores of inductor are arranged in the form of packets, which are assembled from insulated sheets of electrical sheet with high magnetic permeability, number of inductor cores is at least two, even cores of inductor are displaced relative to odd ones in tangential direction by half of teeth division of inductor, between magnetic conductors of inductor there are circular layers arranged from segmental permanent magnets axially magnetised in one direction. Besides certain ratios are maintained between number of explicit anchor poles, number of elementary teeth on explicit anchor pole, number of explicit anchor poles in phase, general number of anchor teeth, number of teeth at each inductor core and number of phases in m - phase winding of anchor of contactless reducer electromagnetic machine with multipack inductor.
EFFECT: provision of high energy and operational indices, high specific rotary torque on shaft and high electromagnetic reduction of rotation frequency in mode of electric motor, and also high specific power at high frequencies of EMF in mode of electric generator.
