Anti-aging and working efficiency of permanent ferrite segment magnet
Jan 07, 2019

The residual magnetic induction strength of the permanent ferrite segment magnet is high. Because Br is high, it can ensure the motor has high speed, large output torque and large power, and the motor will have higher efficiency. Because Hcb is high, it can ensure The motor provides the required electromotive force to bring the motor operating point close to the maximum magnetic energy product, making full use of the magnet's ability.

The permanent ferrite segment magnet magnetic tile can ensure that the motor has strong anti-overload demagnetization and anti-aging and low temperature resistance. High (BH)max. The higher (BH)max, the better the working coefficient of the actual operation of the permanent ferrite in the motor.

The larger the magnetic energy Φ of the permanent ferrite segment magnet magnet, the better, which will greatly improve the working efficiency of the motor. The better the squareness of the demagnetization curve, the smaller the dynamic loss of the motor. The higher the resistivity of the permanent ferrite, the smaller the eddy current loss. The permanent ferrite segment magnet has a small temperature coefficient and good temperature stability at high temperatures.
