Abstract

The invention relates to electrical equipment and can be used to force the inclusion of electromagnetic devices in automation systems. The aim of the invention is to reduce the mass of winding wires. When a power source is connected in the working winding 1, a transition EMF occurs, under the action of which the shunt diode 7 opens. In this case, the separation diode 3 is locked, and the working 1 and starting 2 windings are connected in parallel. After the operation of the switching element 4 and the end of the transition process, the windings are switched on in series. 1 il. with e
