Automobile motor magnetic tile: no need to introduce, used in the car motor a tile / solitary magnet, according to the different motor, inside the magnetic tile types are different, there are dun iron boron magnetic tile, ferrite magnetic tile, but also is the color diamond magnetic tile.
The impact of magnetic tile on the car motor.
1. The greater the magnetic energy the better, which will greatly improve the efficiency of the motor
2. The better the demagnetization curve, the smaller the dynamic loss of the motor.
3. The higher the electropositivity of the permanent magnet ferrite, the smaller the eddy current loss.
4. The temperature coefficient of permanent magnet ferrite is small, so it has good temperature stability under high temperature.
The effect of the performance of the magnetic tile on the motor.
(1) High residual magnetic induction strength Br. because in the same magnetic pole surface area and gas, Br high to produce a large output torque and large power. The motor will only have a high efficiency.
(2) High Hcb. Because high Hcb to ensure the motor output required electric potential, so that the motor operating point near the maximum magnetic energy product, the full use of the energy of the magnet power.
(3) High Hcj. High Hci can ensure that the motor has a strong resistance to overload demagnetization and anti-aging, low temperature resistance.
(4) High (BH)max. the higher the BHmax, the better the actual operating coefficient of the permanent magnet ferrite in the motor.
(5) Magnetic energy Φ The larger the better, which will greatly improve the efficiency of the motor.
(6) The better the rectangularity of the demagnetization curve, the smaller the dynamic loss of the motor.
(7) The higher the resistivity of the permanent magnet ferrite, the smaller the eddy current loss.
(8) The temperature coefficient of permanent magnet ferrite is small, only at high temperature has good temperature stability.
(9) The starting current is small and the time constant is small. The impact on the power supply is small.
