Abstract
Description
Technical Field
[0001] The present invention relates to an electromagnet, and more particularly to a novel electromagnet. Background Art
[0002] Our company's previous electromagnet design has a spring on the moving rod 70, that is, when the electromagnet is energized, the moving iron core is configured to move a predetermined distance in the direction close to the static iron core, and at the same time the retaining ring 80 moves in the direction away from the upper yoke 11, thereby being stretched by the spring.
