摘　　要：电磁兼容性在数控电气控制系统中起着重要作用。根据开放式数控系统的控制特点,以"PC+Turbo PMAC"为硬件平台,分别从Turbo PMAC电源电磁兼容设计、I/O信号电磁兼容设计、光栅编码信号的抗干扰三个方面入手,介绍构建开放式数控系统的电磁兼容设计方法。通过以上电磁兼容设计,使得基于Turbo PMAC的混联机床开放式数控系统控制可靠,运行良好。EMC plays an important role in NC electric control system. According to the characters of open NC system, taking ＂PC ＋ Turbo PMAC＂ as hardware platform, the EMC design method for open architecture NC system was introduced from three aspects, namely the EMC designs of the power source for Turbo PMAC, I/O signal and anti-interference for raster display coding signal. Through the EMC design above, the open NC control system of hybrid machine tool based on Turbo PMAC is reliable and runs in good condition.
