Ferrite magnet: Ferrite magnet has strong anti-demagnetization performance. Ferrite magnets are hard and brittle, requiring special machining process. Because the opposite magnet is oriented in the manufacturing direction, it needs to be magnetized in the selected direction, while the same magnet can be magnetized in any direction because it has no orientation, although a slightly stronger magnetic induction will be found on the side of the pressure surface that is usually small. Due to its low cost, ferrite magnetic steel is often used in the field of electroacoustic equipment, such as speakers, headphones, etc.

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. More bigger 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.
