Pr?sentationstitel Driving the world Product Training Servo Technology 伺服控制技术培训 Advantages and features of a servo drive 伺服驱动的优势及特征 Driving the world 伺服选型 History of servo drives 伺服驱动的历史”Servo” derived from the Latin (slave, servant, assistant) “Servo”一词来源于拉丁语(例如: slave, servant, assistant ) Former application ranges: - mainly used as auxiliary drives (. feed in lathes) 从前的应用范围: - 主要应用于辅助的驱动( 例如. 车床加工机械) Today: - everywhere there is a high demand for dynamics pact design 现在:- 遍及每一个有高动态性能要求的领域. Driving the world 伺服选型 Features of servo drives 伺服驱动的特点 Servo drives are drive systems that exhibit 伺服驱动作为一种系统有广泛的应用: ?Dynamic 高的动态性能? Precise 精确的定位?overload-capable behavior in a wide speed setting range. 非常宽的调速范围和高过载能力(a servo drive is not only a synchronous motor with permanent rotor, but also an asynchronous motor that reaches servo characteristics with certain control modes) (伺服驱动不仅是转子为永磁体的同步伺服电机而且包括异步伺服电机,其性能达到了同步伺服电机的特性水平) Driving the world 伺服选型 Requirements for servo drives 伺服驱动的要求? Positioning accuracy 定位精确? Speed accuracy 高的转速精度? Large speed setting range 宽的转速设定范围? High static torque (n=0) 高的静态转矩( n=0 ) ? Torque stability 转矩稳定? Overload capacity (3-*M ) 高的过载能力( 3-*M ) ? Dynamics 动态特性? Short acceleration time 非常小的加速时间? Small mass moment of inertia 小的电机转动惯量? Low weight 重量低? Compact design (small dimensions) 紧凑的外型尺寸.
