The ferrite magnet ferrite magnetic tile is in the shape of a tile, and its magnetic performance is characterized by high permeability at high frequency. Therefore, ferrite magnetic tile has become a widely used non-metallic magnetic material in the electronic field. Due to the low magnetic energy stored in the unit volume of ferrite, its application in the field of high frequency and high power generation with high magnetic energy density is limited. The advantage is that the cost is much lower than NdFeB magnet. Ferrite magnetic tiles are often used in the fields of electric motors.
The shape of ferrite magnet is the same as that of NdFeB magnet, which can be customized according to customer needs. It can also be divided into square, ring, tile, circular cylinder, including special-shaped magnets. Essentially, the difference between ferrite magnet and NdFeB magnet is that its performance is weaker than that of NdFeB magnet, but its cost is lower and more affordable, and its performance price ratio is higher. Ferrite magnet can be divided into ferrite magnetic steel and ferrite magnetic tile according to its use. The magnetic tile has better air tightness and higher efficiency. The difference between the tile and the straight plate is that the tile can improve the efficiency of the motor at high speed. Because the magnetizing surface of the straight plate magnetic steel is always straight, it cannot achieve the efficiency of the magnetic shoe under the condition of ensuring the air gap is unchanged. The electric vehicle motors all use silicon steel stator. The higher the working frequency, the greater the iron loss, and the magnetic shoe can solve this problem. At the same speed, the working frequency of the silicon steel sheet will also be reduced, and the iron loss will be relatively reduced, The other differences are negligible. Usually, high-power motors choose more magnetic pads.
