Common sense of magnetizer

1, in the process of magnetization, the temperature will directly affect the magnetic saturation, there are forced air cooling, water cooling, low temperature constant cooling and other means;
2. When magnetizing mechanical and electrical container works, the peak value of pulse current is very high, and the performance of capacitor withstand shock current is very high;
3 、 the magnetizing power supply is required to be efficient, stable and high precision, and the magnetic flux of permanent magnet is tested at the same time;
4, when the pulse magnetic field peak value reaches 3~5 times of the coercive force (Hc) in the magnetized coil, the saturable magnetic field can be carried out. If a suitable magnetizing coil is matched, a magnetic field of 30000 OE (Oster) is produced at an instant, and the magnetizing effect is better for a high coercive magnet, such as NdFeB magnet;
5 when the magnet is placed, the horizontal center of the coil is the best with the horizontal center of the magnet
6, choose the magnetizing machine, first voltage high repeat precision, the second is to stable capacitance, foil type capacitors, it is the capacity of the most stable capacitance, many imported magnetizing machine are using this, but also the most expensive price. Most domestic manufacturers are using metal membrane.
