With the rapid development of power electronics technology, microelectronics technology and computer technology, frequency conversion speed regulation technology and vector control technology have been increasingly improved. As frequency conversion speed regulation technology continues to mature, frequency conversion speed regulation devices are increasingly used in belt conveyor equipment. The application of frequency converters on belt conveyors is one example. The various advantages of frequency converters determine its wide application in conveying machinery:

1. You can use a squirrel-cage induction motor. This type of motor is small and can be used like a mechanical speed changer without the need for a speed change part. The drive is small and light.

2. To improve production performance, use a frequency converter to drive a wide range of speed control from 1:10 to 1:20, which can be achieved by changing the cycle number command remotely. Therefore, it is easy to select a speed that is more suitable for work needs.

3. It can start and stop smoothly. If the conveyor belt speed is suddenly changed, the conveyed objects will collapse. For example, if the transportation of glass bottles suddenly stops, the bottles will collide with each other and may be damaged; but if it is operated by a frequency converter, Because it starts with a low frequency, the vibration is small, and after being adjusted with smooth control, the whole process can be stable and satisfactory.
