Problems solved by technology

Such a switch coil 5 is designed according to a closed magnetic circuit, but after the key switch is turned on, the magnetic circuit of the movable iron core and the electromagnetic switch is in an open state, so that the magnetic field force of the metal coil does not fully play like this. The consumption of more metal wires will lead to an increase in the overall manufacturing cost of the starter

Abstract

The invention provides an electromagnetic control mechanism, which comprises a shell, a coil and a plunger, wherein the shell forms the outline of the electromagnetic control mechanism; the coil is used for generating an electromagnetic force acting on the plunger by current; the plunger is positioned in the coil; the coil consists of a pull-in winding and a holding coil; the numbers of turns of the pull-in winding and the holding coil are equal; and the center of gravity of the coil is not positioned at a half of the length of the coil.

Description

technical field [0001] The invention relates to the technical field of starters for automobile engines and other engines, in particular to an electromagnetic operating mechanism and a starter using the electromagnetic operating mechanism. Background technique [0002] The starter is composed of three parts: electromagnetic operating mechanism, DC motor and transmission mechanism. Such as figure 1 as shown in figure 1 It is an electromagnetic switch structure of a starter in the prior art. The electromagnetic switch structure of the starter is mainly composed of a switch housing 4, a switch coil 5, a static contact seat 7, a static iron core 8, a moving contact 12, a moving iron core 1, a maintenance spring 13, and a return spring 11. The switch coil 5 in the electromagnetic switch is composed of an attracting coil and a holding coil. The turns of the two coils are equal and the first ends are connected together for a terminal to lead out. The first end of the attracting c...
