摘　　要：通过结合使用变频器与PLC,制定了牙轮钻机变频调速系统方案,分析了系统的调速原理、加减速特性及机械运行性能。应用结果表明,变频调速系统很好地解决了钻机启动、停止和调速问题,减少了设备维修工作量和维修成本。The frequency control system of the rotary drill rig is established by the combining converter with PLC. The governor principle, characters of acceleration and deceleration, and the mechanical running performance are also analyzed. The practical result indicates that the frequency control system excellently solves the drill problems of starting, stopping, and speed regulation, and reduces the workload of equipment maintenance and cost.
