What are the main uses of magnetic tiles?
  • 询价

  The magnetic tile is mainly used in the permanent magnet DC motor. Unlike the electromagnetic motor that generates the magnetic potential source through the excitation coil, the permanent magnet motor generates a constant magnetic potential source by using the permanent magnet material. The permanent magnet magnetic tile has many advantages instead of electric excitation, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, low in copper consumption, and low in energy consumption.

  The effect of the performance of the magnetic tile 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 ferrite 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 and the time constant is small. The impact on the power supply is small.
