High Speed Magnetic Rotor

In the design of high-speed permanent magnet motor, the materials currently used usually have high coercivity. This is mainly due to the relatively low temperature coefficient of materials with high coercivity, which is more conducive to ensuring high-speed permanent magnets. The temperature of the motor rotor is relatively more stable. At the same time, materials with high coercivity have higher temperature adaptability and are currently used in a wide range of applications with higher temperatures. In addition, materials with higher coercivity usually have relatively higher compression resistance and anti-interference strength, and the centrifugal force that can withstand is relatively higher.
