If you are new to the world of magnets, you may have such questions as what is a magnetic tile, and what is it used for? In short, the magnetic tile is one of the permanent magnets, which is mainly used in permanent magnet motors. To let you have a better understanding of magnetic tiles, in this article we will introduce the classification and application of magnetic tiles.
There are three main types of magnetic tiles according to their raw materials:
1. Ferrite magnetic tile
2. NdFeB magnetic tile
3. AlNiCo magnetic tile
Magnetic tiles are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, permanent magnet motors use permanent magnet materials to generate constant magnetic potential sources. Using permanent magnet tiles to replace electric excitation has many advantages. It can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, and low in energy consumption.
1. High residual magnetic flux density Br. High Br can ensure that the motor has a higher speed, a large output torque, and a large power, and the motor has higher efficiency.
2. High Hcb. Because of the high Hcb, it is possible to ensure the required electromotive force output by the motor, make the motor operating point close to the maximum magnetic energy product, and make full use of the capacity of the magnet.
3. High Hcj. High Hcj can ensure that the motor has strong resistance to overload demagnetization, anti-aging, and low-temperature resistance.
4. High (BH)max. The higher the (BH)max, the better the actual operating coefficient of the permanent magnet ferrite in the motor.
5. The larger the magnetic energy Φ, the better, which will greatly improve the working efficiency of the motor.
6. The better the rectangularity of the demagnetization curve, the smaller the dynamic loss of the motor.
7. The higher the resistivity of the permanent ferrite, the smaller the eddy current loss.
8. The temperature coefficient of permanent magnet ferrite is small, so it has good temperature stability at high temperatures.
