Magnetization method and production process of sintered NdFeB magnetic tile
Nov 14, 2018

The sintered NdFeB magnetic tile is mainly used in a permanent magnet DC motor. When the electromagnetic motor is operated, the electromagnetic potential source is generated by the excitation coil. The permanent magnet motor generates a constant magnetic potential source by using the permanent magnet material. The permanent magnet magnetic tile has many advantages instead of electric excitation, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, low in copper consumption, and low in energy consumption.

Magnetizing method of sintered NdFeB magnetic tile

1. The magnetic tile is separately magnetized, then loaded into the casing, and then assembled as a whole.

2. The magnetic tile is loaded into the casing (sticked) and re-magnetized, then assembled as a whole.

3. The magnetic tile is loaded into the casing (sticked), the finished product is assembled, and finally the whole is magnetized.

Production process of sintered NdFeB magnetic tile

1. The sintered ferrite magnetic tile production process of sintered NdFeB magnetic tile is mainly divided into wet pressure heterogeneity, dry pressure homogeneity and dry pressure anisotropy. The difference between the opposite sex and the sameness is whether there is an orientation magnetic field when the press is formed. Here we mainly introduce the process of wet pressing.

2. The wet pressing process is as follows: the wet pressing process is: raw material - pre-burning - coarse grinding (primary ball milling) - batching - secondary ball milling (wet grinding) - magnetic field forming - sintering - grinding - cleaning - magnetizing. Since the molding slurry contains moisture, the magnetic particles are easily deflected in the magnetic field, so that a higher degree of orientation is obtained than the dry pressing property, and the performance is higher.
