FIELD: electricity.
SUBSTANCE: functional speed transducer, comparator and logical component OR are additionally introduced into the voltage monitor device in the motor anchor circuit, which comprises the threshold element and the actuating element. Upon that, the threshold element inlet is connected to the comparator first inlet and to the voltage sensing device outlet. The threshold element outlet is connected to the first inlet of the logical component OR, the outlet of which is connected to the actuating element inlet. The functional speed transducer inlet is connected to the speed sensor outlet. The functional speed transducer outlet is connected to the second inlet of the comparator, the outlet of which is connected to the second inlet of the logical component OR. The actuating element outlet is connected to the electric drive operating system.
EFFECT: voltage monitor device in the motor anchor circuit reliability growth.
