Capitalists do not want you to know that several factual statements in the magnet manufacturer industry are distinguished based on the law of electromagnetic induction. The function of electromagnetism is to resist electromagnetic induction, but the necessity of electromagnetic energy is not as great as electromagnetic force energy. Electromagnetic energy can be cut out to generate alternating current, which can help the three-phase stator current (electromagnetic induction cabinet) from the frequency converter to the frequency converter. This is higher than the law, and now there are differences in non sinusoidal waves, And this type of motor also adds high-frequency switched reluctance, making the polarity of the rotor closer to sine wave, which makes a difference. （2） The constant force belt and refrigerator have fully demonstrated the working principle of the automatic control system, which is the main feature under general automatic control conditions and is also completely improved. The principle is to ensure that the spiral elevator lighting switch can only maintain power supply to the power grid during operation, and the driver board seat does not deform. Refrigerator - has been comprehensively introduced, but it seems to be the only difference between frequency converters and motors.

Looking at this, we can see that theoretically, an "induction motor" is called an "induction motor", which is a type of motor that can be self reliant. The term "induction motor" refers to the pH between the material and VR (an international communication method for AC motors), which means that they constantly attach importance to and apply variable technology to the stator winding.

Normally, this term 'significant value' has been promoted and used in motor products. However, in the case of efficient operation, such hydraulic components can fully utilize their performance while achieving a prominent technical performance: high efficiency, significant energy saving, and smooth operation are the key to most of our motor manufacturing work. Because Slip ring and brush are maintenance free components.

As the three-phase asynchronous motor ages with the increase of operating years, it is necessary to strengthen the daily maintenance of the motor. Starting from the internal maintenance of the motor, the factors that affect the brush pressure should be classified as follows: heat tracing between the lead end and the frame, and the lead end.

In winter, the temperature is relatively low and the humidity is relatively new. Therefore, effective measures should be taken for electric motors, which is to regularly check the brushes.

When installing the motor, the sound should be easily vibrated, otherwise carbon deposits near the brush may cause poor contact of the leads and intermittent wear.

● Check if the spring of the brush has good reversing function and keep the spring in good condition. The distance between the brush edge and the clutch surface should be maintained at around 2-3mm.

For commutators, it is not advisable to use burn substitutes such as brushes. Instead, solvents without corrosive agents should be used. The interior of the motor must also be grounded, as the brushes are located on the front of the brushes and cannot form sufficient rotation angles.

Cover the components on the brush holder, fix the brush leads from inside the brush box, and clean the brushes on the end cover of the brush box and the back cover of the commutator.

The above are the inspection items before using the electric brush, hoping to be helpful to everyone. Greatly improves the commutation function of the brush during operation, while also reducing brush wear and extending its service life.
