摘要
近年来,永磁同步电动机得到较快发展,因其功率因数高、效率高等特点,在一些地面厂矿应用逐渐增多,某些场所已逐步取代交流异步电机,是一种新型节能电机。但在煤矿井下的应用才刚开始,山西焦煤投资公司与华鑫机电合作,率先在正益、正兴煤业公司推广使用无齿轮永磁电机变频调速皮带,即驱动系统由永磁同步电机与变频器相结合实现动力传递,因为去掉了减速器、液力偶合器,整个驱动系统具有高效、节能、低噪音、免维护、输出转矩大、启动平稳、结构紧凑、体积小、重量轻等优点。运行一年来,工作稳定、维护量小、节能效果良好。
In recent years,the permanent magnet synchronous motor get rapid development,and because the characteristics of high power factor,the high efficiency and so on,the application in some ground factories increase gradually,some places have gradually replaced AC induction motor,is a kind of new energy-saving motor.But the application in underground coal mine is just beginning,Shanxi coking coal investment company collaborates with Huaxin mechanical and electrical company,takes the lead in Zhengyi and Zhengxing coal company promoting the use no gear permanent magnet motor frequency control belts,namely the drive system by permanent magnet synchronous motor combined with frequency converter realizes power transfer,because remove reducer and hydraulic coupler,the whole drive system has advantages such as high efficiency,energy saving,low noise,no maintenance,large output torque,stable starting,compact structure,small volume,light weight and so on.For one year the running is stable,the maintenance quantity is small,energy saving effect is good.
