SV series NdFeB magnetizing and demagnetizing machine
SV series magnetizing and demagnetizing machine is a special equipment for both magnetizing and demagnetizing for neodymium iron boron magnetic steel workpieces. Magnetizing magnetic field is better than 2.0T
2. Working principle
SV-type magnetizing and demagnetizing machine is powered by AC power supply. After rectification, it generates a DC current and transmits it to the electromagnet to generate a magnetic field.
Magnetizing: Put the workpiece into the center of the electromagnet's magnetic field, and apply a direct current to generate a high-strength magnetic field in the center of the electromagnet's magnetic field to saturate the magnetization of the magnet. Stop the power supply and take out the workpiece to achieve the purpose of magnetization.
Demagnetization: Put the magnetic steel into the center of the electromagnet's magnetic field, the direction is opposite to that during magnetization, then the current is applied, and the strength of the demagnetization field is determined according to the coercivity of the magnetic steel, and the corresponding current is applied to the workpiece. For demagnetization, the closer the applied magnetic field is to the coercivity of the workpiece, the better the demagnetization effect.
