The magnetization mode of NdFeb strong magnet

Strong magnet magnetization methods include: thickness direction magnetization, axial magnetization, axial multistage magnetization, internal circular radiation magnetization, radial magnetization, radiation magnetization and so on.The magnetization of ferroboron strong magnet is to magnetize the magnetic material or increase the magnetism of the magnet with insufficient magnetism. Generally, the magnetized magnetic object is placed in a magnetic field formed by a coil through which direct current is passed, which is done by a magnetizing machine. Strong magnet magnetization methods include: thickness direction magnetization, axial magnetization, axial multistage magnetization, internal circular radiation magnetization, radial magnetization, radiation magnetization and so on.
The most important thing to pay attention to is the direction of magnetization, so it is very important to determine the direction of magnetization of the magnet. It is necessary to put the magnetic Ndfeb magnet in a high temperature of 250-300 degrees or in the magnetizing machine. It will slowly begin to demagnetize, and the magnetic force can be retired after half an hour or half an hour.
At present, there are two commonly used reporting methods for magnetization. Method 1: DC magnetization and method 2: pulse current magnetization are the mainstream magnetization methods in the market at present.
1, DC magnetization method: DC magnetization method in the right
Ndfeb magnet magnetization process need to use to the electromagnet for magnetizing apparatus, the electromagnet magnetizing apparatus at the time of magnetization coil will give into the direct current (dc), and then in the size of the gap between the two core can be operated by adjusting nut, we first before filling of ndfeb magnet is need with water treatment on the surface of the magnet, Then we need to put the NdFeb magnet into the core gap of the magnetizing machine clamping, and then through the DC to reach the maximum charging time of 3-4 seconds after the power can be cut off, the magnet magnet has been magnetized.
2. Pulse current magnetization:
Magnetization, pulse current on ndfeb magnet magnetization magnetization device need pulse current, his main composition is of pulse magnetization coil and plant, its magnetic field intensity is high, at work very strong impact current through the magnetization coil, in strong magnetic field makes the magnetization coil in the magnetic moment of magnetization.
