Servo Drive Applications

Servo drives are highly versatile devices used within motion control. We offer a wide range of servo drives that have advanced control technology and are compatible with many of the motors within our range.

Servo drives are available as either AC or DC, we also have a range of harsh environment servo drive for demanding applications.

What is a Servo Drive?

A servo drive can also be called an amplifier, takes a command signal from either position, velocity or current and adjusts the voltage and current applied to a servo motor based on closed loop feedback.

A servo drive forms part of a wider servo system. The system also contains a motor, a controller, and a feedback element. Within the servo system, feedback is continually monitored and adjusted within the closed loop circuits. The controller is responsible for calculating the path or trajectory required and the drive is then used to send the voltage and current to the motor to achieve the motion required within the system.

A servo drive can control torque, velocity, or position. Most commonly they are used to control torque.

Servo Drive Applications

Servo drives are used for many applications. As they are built into wider devices they are found in many different industries.

Some application areas for servo drives include;

  • Aerospace
  • Marine
  • Aviation
  • Satellite Communication
  • Laboratory Automation
  • Arctic Drilling
  • Ground Mobile
  • Extreme Outdoor Operation

Some More Specific Applications

Robotics – servo motors are used on the “joint” of a robot arm to monitor the angle and speed of movement.

Printing press – a servo motor can control the stop/start of the print heads themselves and the movement of the paper ensuring accurate printing.

Conveyor belts – in various manufacturing settings, servo drives are used to start and stop conveyor belts.

Metal cutting machines – the precise motion control that servo motors can provide make them perfect for various metal cutting and forming machines including lathes, milling, grinding, punching and pressing.

Camera focusing – within many cameras there are very small servo motors that help with the auto focus function on the lenses.

Automatic Doors – this is a very common application as automatic doors are used widely in shops and hotels; servo motors control the movement of the door once the signal from personnel has been received.
