- 由具备主从通讯功能(RDCO通讯模块)的ABB变频器可组建双电机甚至多电机变频调速同步系统,这种同步系统大大简化了结构,降低了成本。文章在论述了双电机同步控制系统对硬件的基本要求及变频钻机绞车主从控制的实现方法的基础上,分析了绞车双电机同步调速的实现方式及其在现场应用中应注意的事项,并对常见的同步故障排除方法进行了总结。
ABB frequency converter possessing principal and subordinate communication capability can be used to construct variable frequency speed-control synchronization system with double electric motors even multi electric motors. Such synchronization system has the advantages of simplified configuration and low cost.This paper discusses the basic requirements of synchronization control system with double electric motors for hardware and the implementation method of drawworks principal and subordinate control of variable frequency drilling machine, analyzes further the synchronization speed-control method for drawworks double electric motors, puts forward the matters needing attention in field application, and summarizes the elimination method of synchronization faults.2011,S1(S1): 31-34 收稿日期：2011-8-23分类号：TE933作者简介：耿凯（1983- ），男，山东广饶人，工程师，2006年毕业于河北工业大学，现从事设备管理工作。
