摘要
伺服系统是数控机床的重要组成部分,数控机床的精度和速度指标等往往由伺服系统决定。伺服系统经历了从步进伺服到直流伺服进而到交流伺服的发展过程。而且随着技术的发展,高速高精度加工的直线驱动已成为伺服系统发展的新趋势。
The servo-system is an important part in the CNC machine. It decides the precision of the machine and the speed always. The servo-system experiences the process from the step-servo to the DC-servo, even to the AC-servo period. With the technology developing, it is the "highl-speed and hiph-precision making line drive" that becomes the new main trend of the servo system.
