摘　　要：随着社会的发展,很多煤矿企业应用电动机牵引技术来驱动系统,从而降低故障的发生概率,保障系统运行的可靠性。目前,电动机运行中应用的较为先进的2种牵引方式分别为变频牵引和开关磁阻牵引。比较了这2种牵引方式的工作原理及系统控制,分析了其故障后的成本,为煤矿开采中采用机械设备提供了参考。With the development of society, many coal mining enterprises use electric motor traction technology to drive the system, thus reducing the probability of failure and ensuring the reliability of the system operation. At present, the two most advanced traction methods used in motor operation are variable frequency traction and switched reluctance traction. This paper compared the working principle and system control of these two traction methods and analyzed the cost after failure, which provides reference for the use of mechanical equipment in coal mining.
