Industrial Servo Motors

Servo motors are rotary or linear actuators that enable control of both angular and linear acceleration, velocity, and positioning. There are both brush and brushless servo motors, however brushless is the preferred version for most.

What is a Servo Motor?

In simple terms, servo motors are standalone electric motors that push and rotate parts in machines where a specific task and/or position need to be defined. When a servo motor is given a command, it moves to a position and holds there with resistive force.

A servo motor consists of a rotary or linear motor coupled to a sensor for position feedback, and usually requires a relatively sophisticated controller to control the motor’s angular or linear positioning.

Types

Brush Servo Motors

Brushed servo motors are servo motors that have a winding in the rotor and permanent magnets on the stator. These are sometimes considered the “workhorses” of motion control as they are economical and easy to use. Brushed servo motors produce smooth motion at low speeds with good speed control. They are smaller, more efficient, and cheaper than brushless motors.

Brushless Servo Motors

Brushless servo motors are the servo motor of choice. They have windings in the stator and permanent magnets attached to the rotor. No brushes are used. These servo motors provide high acceleration, high torque, and no maintenance. They offer the highest torque-to-weight ratio and can be used in the most precise, demanding applications.

Applications

Servo motors can be used in a variety of different industries and applications including:

  • Electronics
  • Aerospace
  • Food Processing
  • Pharmaceutical
