滚珠丝杠在机床行业的普遍应用，推动了加工机床行业的快速发展，但机械式传动的局限性，已无法应对日益高速化、高效化切削的发展趋势。直线电动机式就是在这种趋势的需求下产生的一种高速高效传动方式，特别是机床的高速传动发展跨上一个新台阶。德国作为世界先进机床的先驱，20世纪80年代就开始了高速铣削和车削技术的研发。1993年，德国EXCELLO公司推出了世界上第一个由直线电动机驱动的工作台HSC-240型高速加工中心，机床主轴最高速达到24 000r/min，最大进给速度为60n/min，加速度达到1g。

当进给速度为20m/min时，其轮廓精度可达0.004mm。美国的Ingersoll公司紧接着推出了HVM-800型高速加工中心，最大进给速度达到75.20m/m i n。

1996年开始，日本相继研制成功采用直线电动机的卧式加工中心、高速机床、超高速小型加工中心、超精密镜面加工机床、高速成形机床等。从此以后，直线电动机在高速数控机床的应用如雨后春笋般地迅速发展起来。近十年来，世界上各工业发达国家纷纷投入巨资，大力研究、开发成功不少直线电动机驱动的高速数控机床，并逐渐有抢占传统滚珠丝杠市场的态势。

直线电动机加工中心在国外的宝马、通用等著名汽车公司已经有成熟的应用，在国内上汽通用、东风雪铁龙、昌河铃木、海马汽车等也有整线的应用实例。本文从技术分析和应用实例上进行了直线电动机和滚珠丝杠驱动加工中心的对比。图1为Comau Urane25直线电动机高速加工中心。
传动原理分析对比滚珠杠副存任的问题如下：

（1）“旋转电动机+滚珠丝杠副”的直线驱动方式存在着多个弹性环节，当整个系统在高速运动时，会出现刚度下降，同时弹性变形使系统的阶次变高，系统的鲁棒性降低，从而使伺服性能下降。弹性变形是数控机床产生机械谐振的根源。

（2）中间传动环节的存在，增加了运动体的惯量，使得位移和速度响应变慢。

（3）间隙死区、摩擦、误差积累等因素，使进给速度和加速度受到限制。

（4）动转平稳性较差，在高速运动下噪声易发热。

（5）精度保持寿命相对短。
而直线电动机以—个运动部件实现直线运动，则具有以下优点：直接驱动中力是无接触传递的，因此无磨损，使用寿命长，维护简单；传动刚性高，推力平稳，直接驱动，弹性环节减少，系统刚性提高，传动效果高；定位精度和重复定位精度高，可达亚微米级，比伺服电动机及滚珠丝杠副传动的加速度和重复定位精度提高7～10 倍。
