Abstract

PURPOSE:To enable the rapid operation in turn of a group of plural electromagnets by a method wherein operation holding circuits consisting respectively of holding switches are connected to the respective electromagnets being connected in parallel to the secondary side of a transformer. CONSTITUTION:Plural series circuits consisting respectively of the electromagnets 1-1, 1-2,... and selecting switches 5-1, 5-2,... are connected in parallel to the secondary side of the transformer 2, and the operation holding circuits consisting respectively of the holding switches 9-1, 9-2,... to settle the holding times of the respective electromagnets and of diodes 10-1, 10-2,... to prevent the flowing of excess stray current are connected to the respective electromagnets 1-1, 1-2,.... By this way, utilizing the electromagnetic energy being stored in the inductance of the transformer and a group of switches controlling the energy, rapid currents can be made to flow to the electromagnets having inductance to make the group of plural electromagnets to perform the rapid operation in turn.
