Product Description

Pilot Normally Close Type DMF Series Solenoid Armature

Electromagnets use magnetic circuits to convert electrical energy into magnetic energy, and then convert magnetic energy into mechanical energy that causes the moving iron core to move linearly. The electromagnet is usually composed of three main parts: an exciting coil, a static iron core and a moving iron core. According to the current classification through the excitation coil, there are DC electromagnets and AC electromagnets.

The relationship between electromagnetic attraction and stroke (ie, air gap) is called suction characteristics. The sum of the spring force and the force of gravity is called the reaction force characteristic. It is hoped that under any stroke, the suction force of the electromagnet is slightly larger than the reaction force, that is, the movable iron core can be sucked in, and the movement speed is too fast to cause impact and rebound.

This avoids contact welding and burning to improve life. The suction force of the DC electromagnet is inversely proportional to the square of the stroke. When the stroke is large, the suction force is small, that is, the aerodynamic force is small. The suction characteristic curve of the AC electromagnet is relatively flat, that is, there is a large suction force when the stroke is large.

Solenoid Armature

Solenoid valve armature characteristics

1,The static and movable core is made by rustproof and corrosion-resistant material with high magnetoconductivity and low remanence ,and it is also durable and quick.

2,The plunger tube is made by H62 copper or SS304 ,and the tickness for selection is at the range of 0.25-2.5mm.

3,The seat of plunger tube is made by H59 copper or SS304.

4,Adopting the laser solder technology makes the products more perfect and safe.

5,The spring is made by imported stainless Steel Wire ,which has good performance of pressure and restore.

6,The sealant can be heatproof, oilproof and also can be exclusively applicable to food . All can do according to your requirements.

7,The specification is including Normal Open ,Normal Close ,and AC,DC etc. If you have any other requirements pls let us know.

Refer to the starting current and holding current of Solenoid Stem

When the AC electromagnet voltage is constant, the magnitude of the excitation current is related to the resistance of the coil, but it is mainly affected by the stroke. The stroke is large, the magnetic resistance is large, and the exciting current is also large. The current at the maximum stroke is called the starting current, and the current at the time of suction is called the holding current, also called the exciting current. In large electromagnets, the starting current can reach more than 10 times the holding current. The starting current of a small electromagnet can also reach 2 to 4 times the holding current. If the moving iron core is stuck and the starting current continues to flow, the coil heats up extremely and is even burned. Electromagnetic pilot valves with small strokes are not easy to burn. AC electromagnets should not be switched on and off frequently. The life is not as long as the DC electromagnet.

When the voltage is constant, the coil current of the DC solenoid depends only on the coil resistance, regardless of the stroke size. When the moving iron core is stuck, it will not burn the coil. The DC electromagnet can be frequently turned on and off, and the work is safe and reliable. However, if the voltage is too high and the current is too high, the coil will still be burnt.
