DEVICE FOR CAPACITORS OF THE NON motor terminals. This is achieved due to the fact that an additional current source is used as a direct current source. capacitors connected in series with valves between each 2 phase of the motor and a limiting resistor connected to the zero point of the stator winding. The figure shows the electrical circuit of the device described. 25 The device consists of capacitors connected to the winding / stator 2 connected between each phase of the stator and the current limiting resistor 3 connected to the zero zone.
