Embodiment Construction

[0016] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0017] see Figure 1-5 Shown:

[0018] An electromagnet for a contactor, comprising a static iron core (2) and a moving iron core (1), and the static iron core (2) is two "I"-shaped static iron cores (2) placed symmetrically with each other , each "I"-shaped static iron core includes an iron core post (2b) and a pole shoe (2a), the area of ​​the pole shoe (2a) is larger than the area of ​​the iron core post (2b), and each iron core post (2b ) are respectively provided with a coil, the pole surface of the moving iron core (1) includes a first pole surface (11), a second pole surface (12) and a third pole surface (13), and the static The pole surface of the iron core (2) includes a fourth pole surface (21), a fifth pole surface (22) and a sixth pole surface (23), and the fourth pole surface of the pole surface of the static iron core (2) The surface (2...

Abstract

The invention relates to an electromagnet of a contactor, wherein a boss plane is formed on a movable iron core, a groove plane is formed on the static iron core, and on the premise that ampere turnsare not increased, initial attraction force is improved by forming a second magnetic loop, so that energy can be effectively saved, the size of the electromagnet is controlled, and the electromagnet can be applied under the condition that the size is limited. Due to the fact that ampere-turns are low, energy is effectively utilized, impact of the static iron core on the movable iron core in a small air gap is reduced, and the service life of the electromagnet is prolonged.

Description

technical field [0001] The invention relates to an electromagnet, and specifically designs an electromagnet for a contactor. Background technique [0002] When the current DC electromagnet reaches a large stroke, it requires a relatively large volume due to more magnetic flux leakage, requires a large number of ampere-turns, a large coil volume, and a large iron core volume, so it is necessary to increase the iron consumption and copper consumption. [0003] The electromagnets that are widely used now, whether they are traction electromagnets, push electromagnets, brake electromagnets, or electromagnets for various AC contactors, have the common problems of high power consumption, high noise, Severe impact, low service life, high-quality electrical silicon steel plates are required, difficult to process and manufacture, high copper consumption, large volume, poor guiding of the moving iron core, and generally can only be installed vertically when used. In response to these ...
