FIELD: engines and pumps.
SUBSTANCE: during the stopping period of the motor, the winding insulation resistance measurement of the motor is carried out. If the insulation resistance of the winding is equal to or less than the first threshold value, the automatic start of the motor is inhibited and the winding insulation is dried until the insulation resistance of the winding exceeds the second threshold value that is greater than the first threshold value, and when the insulation resistance of the winding of the first threshold value is exceeded, the automatic start of the motor is permitted.
EFFECT: automatic maintenance of the stopped electric motor in working order and safety of automatic start of the electric motor.
