Industrial Servo Motors

A servo motor's primary function is precise control of speed, acceleration, and position. They are essential in many industries, including robotics, automated manufacturing, and even the hobbyist sector, for applications such as remote-controlled cars and planes. The superior precision of servo motors comes from their built-in feedback mechanism, which allows continuous adjustment of the motor's position, speed, and direction in response to the controller's input.

Servo motors come in two main types: brush and brushless. The difference between the two lies in their design. Brush servo motors utilize brushes for commutation - the process of switching the current in the motor's windings. However, these brushes can wear down over time, which may require maintenance.

On the other hand, brushless servo motors do not have brushes, so they don't suffer from the same wear-and-tear issues. Instead, they use a servo drive for electronic commutation. This makes them more reliable and efficient, which is why they're becoming increasingly preferred in many applications.

A typical servo motor includes a motor, a feedback device (such as a rotary encoder), and a controller. The controller sends the motor a signal that dictates what position it should be in. The feedback device, usually an encoder, tells the controller what the motor's current position is. The controller then adjusts the motor's power accordingly to reach and maintain the correct position. This system allows the servo motor to respond quickly and accurately to changes, making it a vital component in many precision applications.

Applications

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

  • Electronics
  • Aerospace
  • Food Processing
  • Pharmaceutical

Brushed vs Brushless Motors

Brushed servo motors are characterized by their winding in the rotor and permanent magnets on the stator. They function using carbon brushes and a mechanical commutator that establishes a current path through the windings to generate motor torque. The brush-type construction allows them to be run with simple motor controls, making them a cost-effective option for certain applications.

However, due to their design, brushed servo motors come with some maintenance requirements. For instance, the brushes, which are either graphite or precision metal, experience wear over time and need to be replaced to ensure optimal operation of the motor. Nevertheless, their high performance, coupled with their ease of use, make brushed servo motors a popular choice for a wide range of applications.

Brushless servo motors are a popular and efficient type of servo motor, characterized by windings in the stator and permanent magnets on the rotor. Eliminating the need for brushes, these motors use electrical commutation performed by a drive for rotation. Renowned for high acceleration and torque, they require no maintenance related to brushes, which enhances their lifespan and reliability. Furthermore, their superior torque-to-weight ratio makes them highly suitable for precision-oriented and demanding applications, despite the requirement of a servo drive for operation.
