Abstract

The invention relates to an electromagnetic actuating device for keeping on starting series connection of coils from parallel connection of coils. An individual electromagnetic actuating device is provided with at least two groups of drive coils, and when the drive coils are connected in parallel or connected in series / parallel in an lower impedance mode, the electromagnetic actuating device is electrified to start so as to acquire a larger starting force; and then, the drive coils are switched by operating a switch device to be connected in series or connected in series / parallel in a higher impedance mode, and the electromagnetic actuating device is electrified, so that the electric current of the drive coils is reduced, but can still ensure that the electromagnetic actuating device has required operation characteristics.

Description

technical field [0001] The present invention relates to an electromagnetic actuating device with coils connected in parallel and held in series. It is aimed at the same individual electromagnetic actuating device that is provided with two or more than two sets of drive coils for current to pass through to generate an electromagnetic actuating effect. The control of the switching device is to control two or more sets of driving coils set in the same electromagnetic actuator, and make a parallel or series-parallel connection with relatively low impedance for energization, and then pass through after the electromagnetic actuator is activated. The control of the switch device switches the above two or more drive coils into a series or series-parallel connection with relatively high impedance to reduce the current passing through the drive coils, but the electromagnetic actuator can still meet the requirements after energized actuation. Operating characteristics to save electric en...
