Low voltage frequency converters are widely used in various industries, such as metallurgy, chemical industry, papermaking, machinery, etc. The specific application is more extensive, with small-scale applications such as blowers, conveyors, feeders, mixers, grinders, crushers, paper cutters, rolling mills, extruder valves, compressors, cooling towers, plastic machinery, elevators, and various textile machinery in various industries. Large application areas include paper mills in paper mills, injection molding machines in mold factories, steel mills in metallurgical plants, as well as large fans, water pumps, cranes, and oil pipelines in chemical and other industries. The use of a frequency converter to form a variable frequency speed control transmission system has achieved or exceeded the performance of a DC speed control system. The frequency converter has the advantages of small size, low noise, and can also use low-cost and easy to maintain asynchronous motors, greatly simplifying the process and reducing initial investment costs. Overall, the use of frequency converters can meet the requirements of improving labor productivity, product quality, equipment automation, quality of life, and living environment. It can also save energy and reduce production costs for enterprises.
