Advantages of Servo Motors

Servo motors are typically AC synchronous brushless motors with built-in positional feedback. Servo motors are used in closed-loop motion control systems where angular position, speed and torque can be very accurately controlled. The rotor of a servo motor uses permanent magnets and can be infinitely positioned between magnetic poles on the stator by varying the voltage and current between windings.

Servo motors are well suited to precision to applications where accurate control of motor speed,  position and/or torque is required.

Advantages of Servo Motors

Servo Motors are used throughout many industries and have the following advantages;

  • High efficiency
  • High output power relative to their size
  • More constant torque at higher speed
  • Closed-loop control
  • Quiet operation
  • Highly reliable
  • High ratio of torque to inertia
  • High acceleration
  • High-speed performance
  • Torque control
  • Smooth running
  • High accuracy
  • Small in size
  • Well suited to varying load applications

What are Servo Motors Used For?

Servo motors can be used in many different applications. The advantages listed above means that servo motors are used more and more in industrial applications to replace conventional AC motors and stepper motors as well as hydraulic and pneumatic systems. There are many applications where servo motors have an advantage. Below are just a few examples:-

  • Machine tools where high accuracy is required.
  • Robotics applications where high accuracy, power and speed are required and low weight and size is an advantage.
  • Conveyer and handling systems where speed and accuracy, as well as high torque, is required.
  • Antenna positioning systems typically need high torque and very high accuracy.
  • Simulation applications where speed, torque and smoothness are important.
  • Renewable energy applications where performance and efficiency are needed.
  • Printing Press where accuracy, speed and reliability as well as low cost is an advantage.

Servo motors, due to their brushless design have advantages in applications in harsh and demanding applications such as:-

  • Food and beverage where motors have to cope with washdown and temperature fluctuations.
  • Defence applications where high shock loads and temperature ranges are seen while high performance is required.
  • Subsea and Oil & Gas application where high pressures and temperatures are seen as well as explosion-proof requirements.
