Problems solved by technology

[0002] The traditional electromagnetic actuation device is driven by the electromagnetic actuation effect generated by the current passing through the driving coil. If the coil energization state does not change when the power is activated and the energized actuation state is maintained, the required start-up excitation current is the same as the maintenance energization actuation current. , large heat loss and waste of electric energy for its lack

Abstract

The invention provides an electromagnetic actuating device for holding energization of a parallel starting part. At least two groups of drive coils arranged in an individual electromagnetic actuating device are started in an opposite lower resistance parallel or serial and parallel connection way to obtain larger starting force, part of the drive coils are energized for excitation by the control switching of a switching device to reduce the current of the drive coils, but the electromagnetic effect acting force of the drive coils can still ensure that the electromagnetic actuating device shows required operation characteristics.

Description

technical field [0001] The present invention relates to an electromagnetic actuating device with parallel start-up part energized and maintained. It is aimed at the same individual electromagnetic actuating device that is provided with two or more than two groups of drive coils for energizing to generate an electromagnetic actuating effect. Through a switch device control, to control two or more sets of driving coils set by the same electromagnetic actuator, and start the parallel or series-parallel connection with relatively low impedance. After the electromagnetic actuator is activated, the switching device The control of the drive coil is switched so that only part of the drive coil is energized and excited, so that the total current of the drive coil is reduced, but the electromagnetic actuator can still meet the required operating characteristics after energized actuation, so as to save electric energy and reduce electromagnetic induction. The heat loss of the drive coil ...
