FIELD: instrument making.
SUBSTANCE: induction motor control system incorporates current static transducer, switcher, switcher control unit, control unit, signalizer, switcher cutoff device, control bus, test signal unit and load cutoff device. Note here that the method to estimate the induction motor operation consists in cutting off the current and load static transducer and feeding the signals with frequency, first, equal to the lower tolerable motor rpm and, then, with that equal to the motor upper tolerable rpm, to the test signal control unit input. In every case the failure signaliser state is recorded.
EFFECT: expanded performances.
