Servo motors are high-precision, high-response-speed electric motors that are widely used in automation systems that require precise control. The following are the main functions of servo motors:
Precise control of speed and position
The servo motor controls the speed and position by receiving pulse signals. Each time a pulse is received, the motor rotates a corresponding angle, thereby achieving precise displacement control. Its positioning accuracy can reach 0.001mm, which is suitable for scenarios that require high-precision positioning, such as CNC machine tools and robots.
Realize closed-loop control
The servo motor has the function of emitting pulses. Each rotation angle will emit a corresponding number of pulses, forming a closed-loop control with the received pulses. This closed-loop system can provide real-time feedback on the rotation state of the motor to ensure the accuracy and stability of the control.
Fast start and brake
The servo motor has the characteristics of small rotational inertia, large starting torque, and rapid braking. It can respond to control signals quickly and is suitable for application scenarios that require frequent start and stop, such as steering gears and automated production lines.
High-precision torque control
The servo motor can convert voltage signals into torque and speed to drive the control object. Its internal rotor is a permanent magnet, and the electromagnetic field controlled by the driver achieves precise torque output, which is suitable for applications that require precise torque control, such as precision instruments and industrial robots.
Adapt to multiple control modes
Servo motors can be controlled in three ways: position, speed, and torque to meet the needs of different application scenarios. For example, in CNC machine tools, servo motors achieve precise processing through position control; in automated production lines, they achieve efficient production through speed control.
