The performance of permanent magnet motor magnetic tile has a great influence on the motor
Mar 09, 2018

The permanent magnet motor magnetic tile is mainly used in the permanent magnet DC motor, and the electromagnetic motor generates a magnetic potential source different from the excitation coil. The permanent magnet motor uses a permanent magnetic material to generate a constant magnetic potential source. Permanent magnet motor magnet has many advantages instead of electrical excitation. The more common, it will also make the motor simple in structure and easy to repair, followed by its light weight, and its It is smaller in volume, more reliable to use, uses less copper, has lower copper consumption, and consumes less energy.

 

The effect of the performance of the permanent magnet motor magnetic shoe on the motor, first of all, is to pay attention to the 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 itself will also have a relatively high efficiency.

 

The influence of the performance of permanent magnet motor tile on the motor is also reflected in the high Hcb. Because Hcb is high, this time can guarantee the electromotive force that the electrical machinery outputs, make the working point of the electrical machinery close to the maximum magnetic energy product, make full use of the ability of the magnet; High Hcj. Hcj high energy directly guarantees that the motor has strong anti-demagnetization, anti-aging and anti-low temperature capabilities.

 

The influence of the performance of the permanent magnet motor tile on the motor is also reflected in the high (BH) max. The higher (BH)max, the better the actual operating coefficient of the permanent magnet ferrite in the motor; the larger the magnetic energy Φ, the better, and this time must be able to greatly improve the working efficiency of the motor.

 

The influence of the performance of the permanent magnet motor magnetic tile on the motor means that the better the squareness of the demagnetization curve, the smaller the dynamic loss of the motor will be. The higher the permanent magnet ferrite of the permanent magnet motor is, the higher the resistivity is. The eddy current loss will also appear smaller; the temperature coefficient of the permanent magnet ferrite is small, and it has good temperature stability under high temperature; next it is said that its starting current is small and the time constant is small, the impact on the power supply It will be smaller.
