A servo motor refers to an engine that controls the operation of mechanical components in a servo system. It is an indirect variable speed device that supplements the motor and can convert voltage signals into torque and speed to drive the controlled object. It mainly consists of motors, usually AC or DC motors, with special designs to provide high precision and performance.
The characteristic of servo motors is that they can achieve precise speed and position control, and have fast response and high stability. They are usually used in applications that require high-precision position control, such as CNC machine tools, printing machinery, etc.
In addition, there are three control methods for servo motors, including torque control, position control, and speed mode. Torque control is the setting of the output torque of the motor shaft to the outside world through the input of external analog signals or the assignment of direct addresses; The position control mode generally determines the rotational speed by the frequency of external input pulses, and the rotational angle is determined by the number of pulses; The speed mode controls the rotational speed through the input of analog signals or the frequency of pulses.
