Abstract

The device is used in electrical drives of mechanisms used in industry and agriculture. It improves the use of the motor power and the reliability of the electrical drive as a whole by means of controlling the lack of matching of the line current and phase voltage and modelling of the heat condition of the motor in symmetrical mode of supply and in the mode of "dropping of a phase". The device consists of a current sensor, voltage sensor, peak detector, scaling amplifier, R-C group, comparator, AND logical element, logical signals shaper, "different pole" logical element, intermediate relay and magnetic starter.
