At present, frequency conversion technology plays an increasingly important role in modern mine production, which can not only improve production efficiency, reduce the workload of daily maintenance of mechanical and electrical equipment, but also play a more and more significant role in energy saving. Belt conveyor is widely used in electric power, chemical industry, metallurgy and other fields of transportation equipment, its work efficiency and stability is an important technical index. Frequency control technology can change the output frequency of the power supply arbitrarily through the frequency converter, so as to adjust the motor speed. The application of frequency control technology to belt conveyor can realize soft start, energy-saving operation and improve the stability of conveying system.<br>
