Information

One Working principle of constant current magnetizer:

By passing a constant current of direct current through the coil, a constant magnetic field is generated in the coil. Suitable for magnetizing low coercivity permanent magnet materials.

II Working principle of pulse magnetizer:

By passing a momentary pulse of high current in the coil, a brief ultra strong magnetic field is generated in the coil. Suitable for high coercivity permanent magnet materials or complex multipole magnetization applications. Widely used in permanent magnet material production and application enterprises, suitable for magnetization of various permanent magnet material parts and components, such as aluminum nickel cobalt series, ferrite series, rare earth permanent magnet series, etc., with high efficiency and reliability. The equipment has no special requirements for workplace power configuration and is easy and flexible to use.

Specifically, the capacitor is first charged with a high DC voltage, and then discharged through a coil with extremely low resistance. The peak value of discharge pulse current can reach tens of thousands of amperes. This current pulse generates a strong magnetic field within the coil, which permanently magnetizes the hard magnetic material placed in the coil. The peak value of pulse current during the operation of magnetizing electromechanical containers is extremely high, and the performance requirements for capacitors to withstand impulse current are very high. The structure of the magnetizer is relatively simple, in fact, it is an electromagnet with extremely strong magnetic force, equipped with various shapes of iron blocks as additional magnetic poles to form a closed magnetic circuit with the charged magnet. When magnetizing, the additional magnetic poles and the charged magnet are arranged, and as long as the excitation current is added, it can be completed in a flash.

Understand various magnetic materials and their magnetization directions 2022-08-11
Permanent magnetic materials, also known as "hard magnetic materials", refer to materials that can maintain constant magnetism once magnetized, with a wide hysteresis loop, high coercivity, and high remanence. There are currently two main types of commonly used permanent magnet materials: the first type is alloy rare earth permanent magnet materials, including neodymium iron boron (NdFeB) and samarium cobalt (SmCo); The second major category is: ferrite permanent magnet materials (Ferrite); The third major category is aluminum nickel cobalt (AlNiCo).

Single pole programmable magnetization technology 2020-07-30
Monopolar programmable magnetization technology is a high-precision programmable magnetization printing technology with small and wide magnetic poles. Applied to high-precision magnetic encoder applications. For example, ABS anti lock magnetic encoder for automobiles, servo motor magnetic encoder, robot joint axis encoder, magnetic grating distance sensor, high-speed elevator variable pole width absolute value encoder, etc. Breaking the technological monopoly of foreign manufacturers in the field of unipolar magnetization, filling the technological gap in China, and reaching the international advanced level.
