Magnetizing machine, is an instrument for magnetic insufficient filled magnetic, is actually a matter of super magnetic electromagnet, the electromagnet and the additional iron to form a closed loop, a magnetizing current flows, generating a magnetic field, to be placed in the magnetic field magnetizing magnet, can brush instantaneous magnetizing. Magnetizer has been applied in electronic, instrument, motor, metal and other products at present.
Two, magnetizing machine principle - Classification
According to the magnetizing machine magnetizing direction can be divided into different thickness and radial magnetization magnetization, magnetization according to principle can be divided into different constant current magnetizing machine and pulse magnetizing machine, then we were working principle of the constant current and pulse magnetizing machine magnetizing machine made by detailed introduction.
Three 、 magnetizing machine principle -- constant current magnetizer
The working principle of the constant current in the electromagnet (magnetizing machine is an important part of the magnetizing machine) closed loop is formed with additional iron which is connected to a constant DC voltage, according to the principle of the electro magnetic coils generate a constant magnetic field, the magnetic field in the magnet magnetizing can complete magnetic charge, such magnetizing machine is applicable to the low coercivity permanent magnet materials magnetization.
Four, magnetizing machine principle - pulse magnetizing machine
The working principle of pulse magnetizing machine is current pulses in the closed circuit of electromagnet and iron formed in the additional pass, the coil produces a transient but strong magnetic field will be placed in the magnetic field can be magnetized magnet magnetized instantaneously, the magnetizing machine has no limit to the power configuration, convenient use, high efficiency, suitable for magnetization in the permanent magnet material parts and components etc..
