摘要
本文介绍一种新型数控机床电涡流伺服系统，它是以电涡流快速离合器作为驱动元件，具有正转、反转、制动功能，构成了新一代伺服系统，它克服了现有伺服系统中一些固有缺点，如低频振荡、零位抖动等，因而具有很多特点：力矩大、反应速度快、定位精度高、成本低等．
A new for eddy-current servo systen of NC machine was developed,characterized bya eddy-current rapid clutch which worked as its drive element,so it has functions such as forward, reverse,and brake. Based on the new power supply,a new servo system for NC machine was developed .which have advantages of high torgue,fast response.accauratepositioning and low price,and it ouercame disadvantages such as low frequeney vibration,Zero drift which present servo system have.
