1. Magnetize the magnetic tile separately, then install it into the casing, and then assemble it as a whole;

2. Install the magnetic tile into the casing (stick it), then magnetize it, and then assemble it as a whole;

3. Install the magnetic tile into the casing (glued), then assemble the finished product, and finally magnetize the entire body.

The impact of different methods on magnetic tile magnetization:

1. The first magnetization method is about 10% lower than the second and third magnetization methods in terms of surface remanence, and generally speaking, using the second magnetization method is more reasonable;

2. The first method of magnetization is very convenient. Some factories use solenoid tunnel magnetization, which has high production efficiency;

3. The second method of magnetization is that some factories use external flushing, while others use internal flushing. The magnetic tiles or rings need to be glued and dried first, which is also very convenient in production;

4. The third method of magnetization is used by many small motors (mostly with three slots). When installing the rotor, it is easy to assemble due to the lack of magnetic force, but it is not convenient to check whether the magnet is properly charged.
