        Introduction to the structure, characteristics and application of magnetic tile

        2017-06-16
        ? ? ? ? The magnet including magnetic tile body, which is characterized in that the magnetic tile body section fan-shaped, outside is a cambered surface, the inside surface is flat, the outer side of the two ends of the main body is provided with a magnetic tile sleeve cap ladder for rotor mounting part, magnetic tile body is provided with a plurality of protrusions on the right side of the left, DC motor magnetic tile is provided with a plurality of grooves, bulges and grooves should be relatively stable installation, easy installation of the fixed rotor cap, without increasing the magnetic tile gap distance, and improve the assembly efficiency of the motor, while improving the durability of motor.
        Influence of magnetic tile on motor
        (1) high remanent magnetic induction Br. Because in the same magnetic pole surface, the massager motor, magnetic tile and air gap, the Br height can produce big output torque and large power. The motor will have higher efficiency.
        (2) high Hcb. Because the Hcb is high, it is necessary to ensure the electromotive force required for the motor output, so that the motor working point is close to the maximum magnetic energy product, and the full capacity of the magnet is utilized.
        (3) high Hcj. Hcj high to ensure that the motor has a strong anti overload, demagnetization and anti-aging, low temperature resistance.
        (4) high (BH) max. (BH) the higher the max, the better the actual working coefficient of the permanent ferrite in the motor.
        (5) the greater the magnetic energy the better, which will greatly improve the 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 temperature coefficient of the permanent ferrite is small, so it has good temperature stability at high temperature
        (9) starting current is small and time constant is small. The impact on the power supply is small.
