Description
Technical field: [0001] The invention relates to a suction device, in particular to a magnetic suction. Background technique: [0002] Existing large magnets (such as magnets for large relays), the iron core is generally made of silicon steel sheets, and the coil must be energized when it needs to be pulled in. , Magnetic shocks are easily generated between the silicon steel sheets, and the temperature of the magnetic attraction rises, which not only affects the surrounding environment, but also affects the normal use of the magnetic attraction if it cannot dissipate heat in time. Invention content: [0003] The object of the present invention is to provide a magnetic attraction with less power consumption, no heat generation, no magnetic loss, and no magnetic shock. [0004] The present invention is realized in this way, including the iron core, the coil wound around the iron core, the armature, the spring between the armature and the iron core. The control circuit is m...
