The types of magnets are as follows: magnets, which should be called magnetic steel, English magnet, magnetic steel is now divided into two categories, one is soft magnetic, one is hard magnetic; soft magnetic contains silicon steel sheet and soft magnet core; hard magnetic contains aluminum Nickel cobalt, milogenesis, iron oxygen, and cymbal iron boron.

How to define the function of magnets? The first is the following three functional parameters to confirm the function of the magnet: magnetic energy accumulation BH: represents the magnetic energy density Servo Motor Magnet factory established by magnets in the air gap space (magnetic pole space of magnets), that is, the static magnetic energy of the volume of the air gap unit.

Magnetic field appearance Magnetic field: Magnetic induction intensity at a specified position of permanent magnet . The intensity of the reverse magnetic field required is called magnetic orthopedic force. During this, the most expensive is the milotic cobalt magnetic steel.What is a powerful magnet?

The highest function of the Magic is rare earth magnets, and the iron boron boron is the most powerful magnet in the rare earth magnet. For example, the REXROTH series concrete pump for 24V ratio solenoid valve is that the current requires the current to 200 ~ 600mA, while the 12V requirements current 400 ~ 1 200mA.

The difference between the power factory and the powerful magnet of the switch -type and proportional formula does not depend on the itself of the powerful magnet. And switch -type powerful magnets are often used to replace the direction of control valves, the system's unloading, loading, etc. The proportional solenoid valve usually requires the current must reach a certain range
