Advantages of permanent magnetic tile material and their influence on the motor
Nov 28, 2018

The permanent magnet tile material is mainly used in the permanent magnet DC motor when it is used. Unlike the electromagnetic motor generating the magnetic potential source through the excitation coil, the permanent magnet motor generates a constant magnetic potential source by using the permanent magnet material. The permanent magnet magnetic tile has many advantages instead of electric excitation, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, low in copper consumption, and low in energy consumption.

Effect of the performance of permanent magnet tile material on the motor

1. High residual magnetic induction Br. Because of the same magnetic pole surface area and air gap, Br high can produce large output torque and large power. The motor will have higher efficiency.

2. High Hcb. Because Hcb is high, the electromotive force required for the motor output can be ensured, and the motor operating point is close to the maximum magnetic energy product, making full use of the magnet's ability.

3. High Hcj. Hcj high can ensure that the motor has strong anti-overload demagnetization and anti-aging, low temperature resistance.
