Some Knowledge Points of Permanent Magnet Coupler

According to Lenz's law, when the conductor of the permanent magnet coupler moves relatively in a magnetic field, the conductor cuts the magnetic induction line, and an induced eddy current is generated in the conductor, which in turn generates an induced magnetic field, and the two interact to generate torque. Depending on the size of the coupling area, an appropriate torque is generated. The greater the coupling area, the greater the torque.

What are the characteristics of permanent magnet coupler

Permanent magnet couplers also have their limitations. According to the classification, different types should be selected to adapt to different working conditions. Can not completely replace the frequency converter, hydraulic coupling and other products (in some special occasions), but also can not replace the reducer, gearbox. There is no energy saving effect on the load of constant torque and constant power. The energy-saving effect of the speed-regulating permanent magnet coupler is only reflected in the equipment with centrifugal load, which is determined by the characteristics of the centrifugal equipment itself, not the characteristics of the permanent magnet coupler itself. Other speed control devices (frequency converter, hydraulic coupling, etc. also have energy saving effect.

Design and Technology of Permanent Magnet Direct Drive Motor

Compared with the induction motor, the permanent magnet direct drive motor does not require reactive excitation current, which can significantly improve the power factor, reduce the stator current and stator loss, and have no rotor resistance loss during stable operation. Therefore, while reducing the total loss, it can reduce the fan and the corresponding wind friction loss, so that its efficiency is 10 to 15 percentage points higher than that of the induction motor of the same specification. In addition, the permanent magnet synchronous motor can maintain a high efficiency and power factor in the range of 25% to 120% of the rated load, making it more energy-saving in light load operation.

What is the application of beam pumping unit with permanent magnet direct drive motor?

At present, the permanent magnet direct drive motor beam pumping unit power transmission adopts motor-belt drive-reducer-four-bar mechanism. The transmission chain is long, and each transmission link consumes a certain amount of energy, especially the belt transmission efficiency is low. Therefore, the transmission efficiency of the system is low, and the energy waste is serious. Today, energy conservation and emission reduction are more and more valued by the whole society. As a participant in energy conservation in the oil industry, we need to re-examine the transmission system of the beam pumping unit. After more than two years of experimental research, we finally developed a direct drive permanent magnet direct drive motor for beam pumping unit, which eliminates the inefficient belt drive and allows the permanent magnet direct drive motor to directly drive the reducer. The transmission chain of the pumping unit becomes: permanent magnet direct drive motor-reducer-four-bar mechanism.

What is the cause of permanent magnet direct drive motor demagnetization?

There are many kinds of magnetic materials and their performance is very different, but they all have the problem of magnetic stability. The stability of permanent magnet direct drive motor is mainly affected by temperature, vibration, time and current impact. The cause of permanent magnet demagnetization is very complicated, which may be caused by one reason or the result of multiple reasons. However, in general, the magnetic loss of permanent magnets is mainly due to material, mechanical, chemical and electromagnetic characteristics.
