Xinhuanet Beijing, December 6th (Reporter Li Bin) Under the condition of frequent changes in speed and load, a new motor speed control system that can make the overall power saving rate of the motor reach 5% or more - switched reluctance motor speed control system A few days ago, the expert identification confirmed that China's motor speed control technology has made important progress. As a "power-consuming" motor, it is expected to further realize energy conservation.
The appraisal team composed of experts from the Chinese Academy of Engineering Yao Fusheng and Tsinghua University professor Li Fahai believes that its "technical performance has reached the international advanced level", it is recommended to further optimize the design, reduce costs, increase promotion efforts, and form a market scale as soon as possible.
Electric motor is the most important power consumption equipment. In China, only small and medium-sized electric motors consume more than 60% of the national power generation. At present, the mainstream of the market is the variable frequency speed control technology with large power consumption. In recent years, the United States, Canada and other countries competed to develop a new technology of switching reluctance motor with good energy-saving effect, and it has been successfully applied to household appliances such as washing machines and vacuum cleaners. As a hot topic in the field of contemporary electric transmission, many research units in China have been working on switching reluctance motor technology since the 1980s, but they have been slow.
After more than three years of hard work, Shandong Kehui Electric Co., Ltd., Shandong Zibo Traction Motor Factory, Shandong University of Technology and other units have jointly developed this new type of motor speed control system - switch type reluctance motor speed control system, in Xinhua, Shandong. The pharmaceutical company, Zibo Thermal Power Co., Ltd. and other units have successfully applied and passed the comprehensive performance test of the National Small and Medium-sized Motor Quality Supervision and Inspection Center, which was listed as the energy-saving product recommended by the National Development and Reform Commission during the 11th Five-Year Plan period.
The new motor speed control system consists of a switch-type reluctance motor and a microcomputer intelligent controller. The appraisal experts believe that this product with independent intellectual property rights has a good application effect in air compressors, plastic machinery, fans, water pumps, papermaking machinery and other speed control occasions, and has already had mass production conditions.
