Arc magnets are mainly used in various DC motors, such as brushless DC motors, permanent magnet DC motors, etc., and magnets are indispensable. So what are the main arc magnet materials used in motors? What are the advantages? Please read on.
Strong magnetic force, can keep the power unchanged, reduce the size of the motor, the starting current is also small, and it is not easy to stall (ie overload). Generally, the temperature resistance H level and above are used.
2. Ferrite arc segmented magnet
It has the advantages of low price, high magnetic permeability, high temperature resistance, and not easy to demagnetize. The proportion of ferrite magnetic tiles in the motor is also large.
3. Bonded NdFeB magnetic tile
Bonded NdFeB magnetic tile is also a kind of magnetic tile, but it is made of bonded NdFeB material, and there are few customers. At least I haven't come across it yet.
4. Samarium cobalt magnetic tile
Samarium cobalt magnetic tiles are mainly used in some high-end motors, with a temperature resistance of up to 300 ℃, and the price is relatively expensive, and most of them are replaced by neodymium arc magnets.
Arc magnets can also be punched, see: Perforated counterbore arc neodymium magnet
At present, the customers on the market are mainly neodymium arc bending magnets and ferrite bending magnets. The production of neodymium arc magnets does not require molds, but ferrite arc magnets do (except for molds). Customers are welcome to provide size consultation. price, sample.
