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).
How to choose a magnetizer? 2021-10-09
Expensive may not necessarily be good, and good may not necessarily be suitable. How to choose the most suitable magnetizing equipment?
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.
