electric motor units的意思|示意

The servo control technology of linear motor and design and manufacture of electric spindle units are discussed.

探讨了直线电机的伺服控制技术和电主轴单元的设计制造等问题；

As well known, the fabricators of electric servo-motor already provide their own servo controller; however, in almost all the case they employ conventional PID in their units.

由于众所周知，加工厂的电动伺服电机已经提供自己的伺服控制器，但是，几乎在所有情况下，他们在他们的单位常规pid。
