一、数控机床对主轴电机和伺服电机的要求不同：
数控机床对进给伺服电机的要求主要为:
(1)机械特性:要求伺服电机的速降小、刚度大
(2)快速响应的要求:这在轮廓加工，特别对曲率大的加工对象进行高速加工时要求较严格
(3)调速范围:这可以使数控机床适用于各种不同的刀具、加工材质适应于各种不同的加工工艺
(4)一定的输出转矩，并要求一定的过载转矩。机床进给机械负载的性质主要是克服工作台的摩擦力和切削的阻力，因此主要是"恒转矩"的性质。
对主轴电机的要求主要为:
(1)足够的输出功率，数控机床的主轴负载性质近似于"恒功率"，也就是当机床的主轴转速高时，输出转矩较小主轴转速低时，输出转矩大即要求主轴驱动装置要具有"恒功率"的性质

一些厂家生产的所谓硅藻泥，根本就没有硅藻土成分。硅藻泥行业标准指出，硅藻成分应该可检出。如何挑选真正的硅藻泥如何才能挑选到真正的好的硅藻泥?业内人士表示，消费者可以一看二喷三闻。首先，看资质。硅藻泥厂商要有建材主管部门颁发的证书或权威部门出具的检测报告，也就是说，硅藻泥要拥有合法的身份。这一方面是确保企业拥有硅藻泥生产的相关技术和生产资格，另一方面，也为消费者的权益提供了保障。其二，喷水实验。
运动控制器控制伺服电机通常采用两种指令方式：
1、数字脉冲
这种方式与步进电机的控制方式类似，运动控制器给伺服驱动器发送“脉冲/方向”类型的脉冲指令信号；伺服驱动器工作在位置控制模式，位置闭环由伺服驱动器完成。日系伺服和国产伺服产品大都采用这种模式。其优点是系统调试简单，不易产生干扰，但缺点是伺服系统响应稍慢。
2、模拟信号
这种方式下，运动控制系统给伺服驱动器发送+/-10V的模拟电压指令，同时接收来自电机编码器或直线光栅等位置检测元件的位置反馈信号；伺服驱动器工作在速度控制模式，位置闭环由运动控制器完成。欧伺服产品大多采用这种工作模式。其优点是伺服响应快，但缺点是对现场干扰较敏感，调试稍复杂。
