Magnetic tile is mainly used in permanent magnet DC motor. Unlike electromagnetic motor, which produces magnetic potential source through excitation coil, permanent magnet motor is a permanent magnetic potential source by permanent magnetic material.Permanent magnet magnetic tile instead of electric excitation has many advantages, which can make the motor simple structure, convenient maintenance, light weight, small volume, reliable use, less copper consumption, low copper consumption, small energy consumption, etc.

Effect of the performance of the magnetic tile on the motor

(1) High residual magnetic induction strength Br.Because Br is high to ensure that the motor has a high speed, large output torque and high power.The motor will have a higher efficiency.

(2) High Hcb.Because of the high Hcb, to ensure the electric potential required for the motor output, make the motor working point close to the maximum magnetic energy product, and make full use of the ability of the magnet.

(3) High Hcj.Hcj can ensure that the motor has strong resistance to overload antimagnetization, aging and low temperature.

(4) High (BH) max.(BH) The higher the max, the better the actual operating coefficient of the permanent magnet oxide in the motor.

(5) The greater the magnetic energy, the better, which will greatly improve the working efficiency of the motor.

The better the rectangle of the (6) demagnetic curve, the smaller the dynamic loss of the motor.

The higher the resistivity of the (7) permanent magnet oxide, the smaller the vortex loss.

(8) The temperature coefficient of permanent magnet oxide is small, which has good temperature stability at high temperature
