Tile effect on motor performance
Jan 16, 2017

(1) the residual magnetic flux density Br. Br high to ensure the motor has high speed and large output torque and power. Motor has a higher efficiency.

(2) higher Hcb. Because Hcb high in order to ensure that the EMF of the motor output required, the motor working points close to the maximum energy product, the ability to take full advantage of magnet.

(3) the Hcj. Hcj high ensures that the motor has strong overload of demagnetization resistance and aging resistance, low temperature capability.

(4) high (BH) max. (BH) Max high ferrite magnet motor coefficient of the actual operation of the work as possible.

(5) magnetic energy φ bigger is better, this would improve the efficiency of the motor.

(6) rectangular demagnetization curve, the better, the dynamic smaller losses.

(7) the higher the resistivity of ferrite magnet, Eddy current loss is smaller.

(8) ferrite temperature coefficient is small, only at high temperature with good temperature stability
