Problems solved by technology

[0002] The traditional electromagnetic actuation device is driven by the electromagnetic actuation effect generated by the current passing through the drive coil. If the drive coil is not changed when the power is started and the power-on actuation state is maintained, the required start-up excitation current is the same as the power-on actuation current. Large loss and waste of electric energy are its defects

Abstract

The invention relates to an electromagnetic actuator with driving and maintaining tapped coils, which is an operable electromagnetic actuator exciting electrifying start to a driving tap and a common connector at low impedance state so as to acquire larger starting force; the operable electromagnetic actuator switches a maintaining tap and the common connector at high impedance state and maintains the excitation of the low current so that the electromagnetic actuator has required running feature.

Description

technical field [0001] The present invention relates to an electromagnetic actuating device with driving and holding tap coils, aimed at an electromagnetic actuating device with driving coils having driving taps, holding taps and common joints, through the control of the switch device, the pair is lower Impedance-driven taps and drive coils of common joints are used for energized excitation, and after the electromagnetic actuator is activated, through the control of the switch device, it is switched to keep the drive coils of higher impedance holding taps and common joints for energized excitation. The total current of the driving coil is reduced, but the electromagnetic actuating device can still meet the required operating characteristics after electrified actuation, so as to save electric energy and reduce the heat loss of the driving coil of the electromagnetic actuating device. Background technique [0002] The traditional electromagnetic actuation device driven by the ...
