10.0mm OD Automobile Spare Part Brass 3 Way Solenoid Valve Armature

According to the current passing through the excitation coil, there are DC electromagnets and AC electromagnets.

Because there is no hysteresis eddy current loss in the DC electromagnet, the core can be made of a whole piece of ferromagnetic material. The moving iron core is often made into a cylindrical shape, called I-shaped electromagnet or solenoid type electromagnet. Compared with T-shaped electromagnet, it has compact structure, small volume, short stroke, light movable parts, small impact force and full air gap. In the solenoid coil, the suction force is greater. However, the DC electromagnet must prevent excessive remanence from affecting normal operation.

When alternating current is applied to an AC electromagnet, there is a hysteresis eddy current loss in the iron core. On small electromagnets and solenoid pilot valves, integral I-shaped electromagnets can be used. For direct-acting solenoid valves that require greater suction, in order to reduce iron loss and heating, T-shaped electromagnets are often used. The iron core is made of silicon steel sheets to reduce iron loss and heating. The movable part of the T-shaped electromagnet has a large weight and a large impact force during action, but a large suction force and a large stroke.

The core tube contains and guides the core. It also retains the plugnut and may seal the fluid. To optimize the movement of the core, the core tube needs to be nonmagnetic. If the core tube were magnetic, then it would offer a shunt path for the field lines.[10] In some designs, the core tube is an enclosed metal shell produced by deep drawing. Such a design simplifies the sealing problems because the fluid cannot escape from the enclosure, but the design also increases the magnetic path resistance because the magnetic path must traverse the thickness of the core tube twice: once near the plugnut and once near the core. In some other designs, the core tube is not closed but rather an open tube that slips over one end of the plugnut. To retain the plugnut, the tube might be crimped to the plugnut. An O-ring seal between the tube and the plugnut will prevent the fluid from escaping.
