Electromagnet according to action methods of classification of the type and suction

by:Newland     2020-04-23
Electromagnet according to action methods of keeping type and suction type of classification: such as electromagnetic clutch, electromagnetic chuck and lifting electromagnet suction: all kinds of automatic electric relay, contactor, solenoid valves, electric hammer and bell, etc. 1. According to the classification of the excitation coil power supply: dc, ac 2. According to the movement speed of classification: rapid action, normal action, slow action 3. According to the movement of the armature methods of classification: straight moving type, rotation type 4. According to the shape of the magnetic circuit categories: open magnetizer such as solenoid; Closed-circuit magnetizer such as disc ( Lifting electromagnet) , making jewels, Ⅱ, Ⅲ ( And E) , armored solenoid note: general on the industrial structure, based on the can simply merged into three types: making jewels: disc type, Ⅱ in principle can be classified into such, the class shortest trip. Electromagnet can be electricity flow to generate the magnetic device, belongs to the permanent magnets, can easily will start its magnetic or eliminated. For example: large cranes use of electromagnet to raise abandoned vehicles. When a current flows through a wire, a magnetic field around the wire. Application of this nature, by running a current through the solenoid, would be made uniform magnetic field in the solenoid. Suppose in the center of the solenoid in ferromagnetic materials, then this magnet material can be magnetized, and will greatly enhance the magnetic field. Magnet, powerful magnets, special-shaped magnets, magnet manufacturer,
