舵机英文叫Servo，也称伺服机。其特点是结构紧凑、易安装调试、控制简单、大扭力、成本较低等。舵机的主要性能取决于最大力矩和工作速度(一般是以秒/60°为单位)。它是一种位置伺服的驱动器，适用于那些需要角度不断变化并能够保持的控制系统。-Servo English called Servo, also known as servo. It features compact structure, easy installation, simple control, large torque, low cost and so on. The main steering gear and work performance depends on the maximum torque speed (generally based on seconds/60 ° of units). It is a position servo drive for those in need of a changing point of view and be able to maintain the control system.
