(Summary description)1. The working principle of the constant current magnetizer: the constant current direct current is passed through the coil, so that the coil generates a constant magnetic field. It is suitable for the magnetization of low coercivity permanent magnet materials. 2. The working principle of the pulse magnetizer: the instantaneous pulse high current is passed through the coil, so that the coil generates a short-term super magnetic field. Suitable for high coercivity permanent magnet materials or complex multi-pole magnetization. It is widely used in permanent magnet material production and application enterprises. It is suitable for the magnetization of various permanent magnet material parts and components, such as: AlNiCo series, ferrite series, rare earth permanent magnet series, etc. It has the characteristics of high efficiency and reliability. The equipment has no special requirements for the power configuration of the workplace.

Information

1. Working principle of constant current magnetizer:

A constant current is passed through the coil to generate a constant magnetic field. It is suitable for the magnetization of low coercivity permanent magnet materials.

2. Working principle of pulse magnetizer:

The coil generates a short-term super-strong magnetic field by passing a momentary pulsed high current in the coil. Suitable for high coercivity permanent magnet materials or complex multi-pole magnetization. It is widely used in permanent magnet material production and application enterprises. It is suitable for the magnetization of various permanent magnet material parts and components, such as: AlNiCo series, ferrite series, rare earth permanent magnet series, etc. It has the characteristics of high efficiency and reliability. The equipment has no special requirements for the power configuration of the workplace, and is convenient and flexible to use.

Specifically, the capacitor is charged with a high DC voltage and then discharged through a coil with very little resistance. The peak value of the discharge pulse current can reach tens of thousands of amperes. This current pulse creates a strong magnetic field within the coil, which permanently magnetizes the hard magnetic material placed in the coil. When the capacitor of the magnetizer is working, the peak value of the pulse current is extremely high, and the performance of the capacitor to withstand the impact current is very high. The structure of the magnetizer is relatively simple. In fact, it is an electromagnet with strong magnetic force. It is equipped with iron blocks of various shapes as additional magnetic poles to form a closed magnetic circuit with the magnetized body. To be magnetized, as long as the exciting current is added, the brushing can be completed in an instant.
