Segment Magnet Performance Directly Affects Working Efficiency of Motor

Automobile motor magnetic tile: The two phases of alternating current are respectively fed into two or four sets of motor coil windings to form a rotating magnetic field in the motor. The rotating magnetic field generates an induced current in the rotor of the motor, and the magnetic field generated by the induced current and the direction of the rotating magnetic field Instead, it is pushed and pulled by the rotating magnetic field into a rotating state.

     The influence of automobile motor magnetic tile on the motor:

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

Segment Magnet Performance Directly Affects Working Efficiency of Motor

     The effect of the performance of Segment Magnet on the motor:

(1) High residual magnetic induction Br. Because of the same magnetic pole surface area and 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 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 actual operation of the permanent ferrite in the motor.
(5) The larger the magnetic energy Φ, the better, which will greatly improve the working efficiency of the motor.
(6) The better the squareness of the demagnetization curve, the smaller the dynamic loss of the motor.
(7) The higher the resistivity of the permanent ferrite, the smaller the eddy current loss.
(8) The ferrite has a small temperature coefficient and good temperature stability at high temperatures.
(9) The starting current is small, the time constant is small, and the impact on the power supply is small.
