Frequently asked questions:

1. What is a servo motor?
A servo motor is a motor used in a closed-loop control system to control position, speed and/or torque precisely. A typical servo system includes:
  • Motor (AC or DC)
  • Feedback device (encoder/resolver)
  • Servo drive (amplifier/controller)
2. How does a servo motor work?
A servo motor operates within a closed-loop control system. A desired position, speed, or torque is set, and a controller or drive constantly monitors a feedback sensor (commonly an encoder or resolver) to assess the actual motion of the motor. It compares this measurement to the command to determine an error and then modifies the power supplied to the motor (by regulating the current through the windings) so that the motor accelerates, decelerates, or maintains its position until the error approaches zero. If the load shifts the shaft away from the target, the feedback identifies this change, and the controller automatically increases or adjusts the torque to correct the position. This capability is why servos can achieve precise movements and hold positions accurately, even when subjected to varying loads.
3. How is a servo different from a stepper motor?
A servo motor operates in a closed-loop system, which allows it to deliver higher speeds and strong torque across a wider speed range, making it well suited to dynamic motion and applications that require high precision even when loads change.
A stepper motor is often run open-loop (though some systems use closed-loop control), is generally simpler and more cost-effective, and works well for lower-speed positioning. However, it can miss steps if the load exceeds its capability.
4. What is a servo motor used for?
A servo motor is used to precisely control angular or linear position, speed and torque in applications that demand high accuracy and repeatability. Common uses include robotics, CNC machine tools, packaging lines, printing presses, conveyor systems and metal-forming machinery.
5. What control modes do servo systems support?
Common servo control modes include torque (current) mode, which regulates motor torque directly by controlling current; speed mode, which maintains a commanded rotational speed (rpm); and position mode, which moves the axis to a specified position using inputs such as step/pulse signals or fieldbus position commands.
6. What is the working principle of servo motor?
A servo motor works on the principle of pulse width modulation (PWM), where the angle of rotation is controlled by the pulse duration.
