関する。DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a bridge rectifier and an electromagnetic armature which is closed at the retraction nose between the bridge rectifier and the dc terminals of the bridge;
This invention relates to an electromagnet excitation circuit consisting of a single winding connected in series to the n-reducing contact and a pressure-reducing resistor connected in parallel to the F-reducing contact, which are heard during the arm's holding phase.

整流電流は減少される。In the excitation 1ω path as shown in j-, the amount of the electromagnet's Amazonian pull-in process is reduced by the pressure-reducing contact and the IF resistance is π.
The rectified current flowing in the winding is important because the However, in the armature holding phase, a pressure reducing resistor is introduced into the circuit, thereby reducing the rectified current flowing in the windings.

回路に用いることをできなかった。The disadvantage of conventional circuits is that they require the use of high-power pressure-reducing resistors, which are expensive and easily damaged, so they are used in circuits with single-stranded windings. I couldn't do that.
