Description

[0001] Technical field

[0002] 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.

[0003] Background technique

[0004] 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 base 7, a static iron core 8, a moving contact 12, a moving iron core 1, a maintaining spring 13, and a return spring 11, etc. The switch coil 5 in the electromagnetic switch is composed of an attracting coil and a holding coil. The first ends of the two coils are connected together with an equal number of turns, and a terminal is used to lead out. Th...
