NON-REVERSIBLE CONTROL CIRCUIT OF SELF-BRAKING INDUCTION MOTOR WITH DISPLACING SQUIRREL-CAGE ROTOR Russian patent published in 2024 - IPC H02P1/10 H02P3/20 H02P25/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to drive an electric drive with a self-braking induction motor with a displacing rotor. Non-reversible control circuit of a self-braking induction motor with a displacing squirrel-cage rotor comprises a non-reversible magnetic starter consisting of a contactor with its coil and three built-in thermal protection relays, a double-pole contactor with its coil, automatic circuit breaker, fuses, a control circuit consisting of a control button connected in series with the contactor coil, a time relay with a time delay for the operation of the double-pole contactor. Ends of motor windings have common point to which neutral wire is connected.

EFFECT: improvement of operational characteristics, namely reduction of starting currents of stator winding, increase of intensity of starts, operational reliability and service life of electric motors.
