了解一下西门子伺服电机的概念
浏览次数:222发布日期:2019-09-06
   西门子伺服电机可使控制速度,位置精度非常准确,可以将电压信号转化为转矩和转速以驱动控制对象。伺服电机转子转速受输入信号控制,并能快速反应,在自动控制系统中,用作执行元件,且具有机电时间常数小、线性度高、始动电压等特性,可把所收到的电信号转换成电动机轴上的角位移或角速度输出。分为直流和交流伺服电动机两大类,其主要特点是,当信号电压为零时无自转现象,转速随着转矩的增加而匀速下降。

  3、西门子伺服电机内部的转子是永磁铁,驱动器控制的U/V/W三相电形成电磁场,转子在此磁场的作用下转动,同时电机自带的编码器反馈信号给驱动器,驱动器根据反馈值与目标值进行比较,调整转子转动的角度。伺服电机的精度决定于编码器的精度(线数)。
