Servo Motor

Q1. What is a servo motor?

A servo motor is a rotary or linear actuator that allows precise control of position, speed, and torque. It is commonly used in robotics, CNC machines, automation, and motion control applications.

Q2. How does a servo motor work?

A servo motor operates using a feedback control system. It receives a command signal (desired position or speed), compares it with actual feedback from an encoder or resolver, and adjusts the output to minimize error.

Q3. How is a servo motor controlled?

Servo motors are controlled using a servo drive that interprets control signals (like PWM, analog, or digital commands) and adjusts motor movement based on encoder feedback.

Q4. What are the main types of servo motors?

AC Servo Motor
DC Servo Motor
Brushless Servo Motor
Instruction List (IL)
Linear Servo Motor

Q5. Do servo motors require maintenance?

Yes, but minimal. Regular checks for overheating, lubrication (for some models), and ensuring proper alignment of feedback systems are recommended. Brushless servo motors need less maintenance.

Q6. Can servo motors be connected to PLCs or controllers?

Yes. Servo motors can be easily integrated with PLCs, CNC controllers, HMIs, and motion controllers via communication protocols like EtherCAT, Modbus, CANopen, or Ethernet/IP.
