当前，FANUC大的伺服电机a3000HVis规格如下：额定输出功率250kW，大功率530kW，堵转转3000Nm，大输出转矩为5300Nm，高转速为2000r/min，目前，也是上大的伺服电机。这种电机主要应用在数控注塑机和冲压机上，原先，这些机械主要采用液压驱动。图1 直线电机与直接驱动伺服传统设计和制造的NC机床受制于标准驱动装置及控制器，使加工的精度和速度受到限制。在上世纪80年代末出现了直线伺服电机。它由两个元件组成，电磁力直接作用于移动元件而无需机械连接，没有螺距周期误差，

精度完全依赖于反馈系统和分级的支承。由全数字伺服驱动器供电，刚性高，频响好，因而可获得高速度。比如L17000C3/2is 的直线电机： 大推力可达17000N， 连续推力3400N/4080N/6800N(分别对应自然冷/气冷/水冷)，速度可达4m/s，加速度30g， 分辨率可达0.01µm，甚至更高。直线电机与旋转电机相比，主要有如下几个特点：一是结构简单，由于直线电机不需要有旋动变成直线运动的附加装置，因而使得系统本身的结构大为简化，重量和体积大大地减少；二是定位精度高，在需要直线运动的地方，直线电机可以实现直接传动，因而可以消除中间环节所带来的各种定位误差，故定位精度高；三是反应速度快、灵敏度高，可做到滑块和定子之间始终保持一定的空气隙而不接触，这就消除了定子、滑块间的接触摩擦阻力，因而大大地提高了系统的灵敏度、快速性和随动性；四是工作安全可靠、寿命长。
