永磁电动机在矿井中的应用实践

Application of Permanent Magnet Motors in Mines in Practice

永磁电动机凭借自身结构简单、能效高、成本低的特点在煤矿井下有着良好的应用前景。大阳煤矿年产煤炭180万t,现由于自身交流电动机在驱动带式输送机时存在能耗比高、维护困难的原因,将原设备进行永磁电动机的替换工作,最终约节省80万元/年的使用成本,获得了良好的实际使用经验。

The permanent magnet motor has a good prospect of application in underground coal mines due to its simple structure,high energy efficiency and low cost.The Danyang coal mine has an annual production capacity of 1.8 million tons of coal.Now,due to the high energy consumption ratio and maintenance difficulties of its own AC motor in driving the belt conveyor,the original equipment was replaced with a permanent magnet motor,which eventually saved about 0.8 million yuan per year of usage cost and gained good practical experience.
