Specifications
Magnetic tiles are mainly used in permanent magnet DC motors. Unlike electromagnetic motors, which generate magnetic potential sources through excitation coils, permanent magnet motors use permanent magnet materials to generate constant magnetic potential sources. 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, less copper consumption, low copper consumption, and low energy consumption.
the influence of the performance of the magnetic tile on the motor
(1) High residual magnetic induction intensity Br. Because under the same magnetic pole surface area and air gap, high Br 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 by the motor output can be ensured, so that the working point of the motor is close to the magnetic energy product, and the ability of the magnet can be fully utilized.
(3) High Hcj. High Hcj can ensure that the motor has strong anti-overload demagnetization and anti-aging, anti-low temperature capabilities.
(4) High (BH)max. the higher the (BH)max, the better the actual working coefficient of the permanent magnet 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 temperature coefficient of permanent magnet ferrite is small, and it has good temperature stability at high temperature
(9) the starting current is small and the time constant is small. the impact on the power supply is small.
