The Function And Selection Of Motor Magnets

The function and selection of motor magnets
Motor magnets are mainly used in various motor products, such as generators and various motors, such as rolling gates, electric vehicle motors, servo motors, etc. So what is the role of the motor magnet? Why do you have to use magnets?

In the motor, the magnet is used as a part of the magnetic circuit, and the controller supplies variable frequency power to the coil to generate a magnetic field to drive the motor to run.

 

What kind of magnet is better to use in the motor?

The choice of motor magnet depends on the customer's usage, what effect needs to be achieved and the price and cost accepted.

NdFeB magnetic tile: NdFeB has strong magnetic force, small size, light weight, stronger magnetic force than ferrite, but limited temperature resistance, only about 180 degrees.

Ferrite magnets: The magnetic force is not as good as that of NdFeB, but the temperature resistance is much stronger than that of NdFeB.

There are also samarium cobalt magnetic tiles and bonded NdFeB magnetic tiles. While the temperature resistance is improved, the price will also increase.
