With motor and drive control technology it appears "direct drive" linear motor, which eliminates intermediate links and drive the load directly, eliminating the gap caused by the mechanical transmission, compliance and other related issues. 随着电机及其驱动控制技术的发展,出现了直接驱动直线电机,它取消中间传动环节而直接带动负载运动,消除了由机械传动带来的间隙、柔度以及与之相关的其它问题。
