とから成る電磁石用励起回路に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a bridge rectifier and a bridge rectifier.
A single winding connected in series with a pressure reducing contact which closes in the retraction phase of the armature of the electromagnet and opens in the retention phase of this armature between the terminals, and a pressure reducing contact connected in parallel with the pressure reducing contact. The present invention relates to an electromagnet excitation circuit comprising a resistor.

る。 In such an excitation circuit as described above, the pressure reducing resistor is short-circuited by the pressure reducing contact during the retracting process of the armature of the electromagnet, so that the rectified current flowing in the winding is important. However, during the armature holding phase, a pressure reducing resistor enters the circuit, thereby reducing the rectified current flowing in the windings.
