The influence of the performance of the fan motor ferrite magnet on the motor
Aug 06, 2018

The fan motor ferrite magnet is mainly used in the permanent magnet DC motor to some extent. When the electromagnetic motor is operated, the magnetic potential source is generated by the excitation coil. The ferrite magnet of the fan motor is mainly produced by the permanent magnet material. Constant magnetic potential source, permanent magnet magnetic tile instead of electric excitation has many advantages, which can make the motor ferrite magnetic tile simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, less in copper consumption, low in copper consumption, and energy consumption. Small.

The influence of the performance of the fan motor ferrite magnet on the motor

1. The high residual magnetic induction Br of the ferrite motor of the fan motor, because the same height of the magnetic pole and the 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 electric motor magnetic tile can ensure that the motor has strong anti-overload demagnetization and anti-aging, low temperature resistance.

4. High (BH)max. The higher (BH)max, the better the working coefficient of the permanent ferrite magnet running in the motor.
