FIELD: electric engineering. ^ SUBSTANCE: one-phased inductive electric motor contains a device which prevents consumption of power, which includes signal transmission element and a switch. The switch opens/closes depending on current signal received from current signal transmission element. Power consumption preventing device does not allow influx of current into launching device during operation of electric motor in normal mode. ^ EFFECT: prevented consumption of power by launching device during operation of motor in normal mode, efficiency of one-phased inductive electric motor is not reduced. ^ 2 cl, 6 dwg |
