THREE-PHASE ASYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2017 - IPC H02K17/28 H02K17/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely, to three-phase asynchronous electric motors. Three-phase asynchronous electric motor comprises a stator, consisting of a housing, hollow steel laminated cylindrical core with slots on the inner surface, attached from the inside to the housing, bearing in slots the network and compensation windings, isolated relative to each other, rotor, installed inside the steel core of the stator with a uniform air gap, made in the form of a steel hollow cylindrical core, fitted on a shaft and bearing slots with winding on the external surface, two bearing shields, fixed at the stator ends, in which there is a shaft of the rotor with shaft bearings, pressed on the shaft, and capacitive elements, connected to the bases of the compensation winding phases. Capacitive elements are capacitive elements with non-linear dependence of the capacity from the voltage value on their plates, for example voltage-controlled capacitors.

EFFECT: technical result is higher quality of voltage in a supply network, working and operational characteristics of electric energy consumers.
