Brush Servo Motor vs. Brushless Servo Motor: which is better for my application?

By Warren Osak, CEO of Electromate

A common misconception is that a brushless servo motor is always going to be a superior solution to a brush servo motor.  In many industrial automation applications, this assumption can be furthest from the truth.  A comparison of the benefits and drawbacks of brush and brushless servo motors is described in this White Paper.

Do you know the difference between these 10 types of servomotors?

Servomotors are generally used as a high performance alternative to the stepper motor. Stepper motors have some inherent ability to control position, as they have built-in output steps. This often allows them to be used as an open-loop position control, without any feedback encoder, as their drive signal specifies the number of steps of movement to rotate. This lack of feedback though limits their performance, as the stepper motor can only drive a load that is well within its capacity, otherwise missed steps under load may lead to positioning errors. The encoder and controller of a servomotor are an additional cost, but they optimize the performance of the overall system (for all of speed, power and accuracy) relative to the capacity of the basic motor. With larger systems, where a powerful motor represents an increasing proportion of the system cost, servomotors have the advantage….

Live Webinar: DC Motor Types and Usage in Typical Applications

February 03, 2015  11:00am EST

This webinar gives you guidelines for selecting the perfect DC motor type for your application.  For example, which motor type is used in the climate control system of the Boeing Dreamliner, and for what reasons?

  • Is a brushed or a brushless design more adapted?
  • Does a flat pancake type motor fit better or should it be an elongated cylindrical one?
  • Are motors with a slotted iron core winding design the right choice, or should it be a motor with a slotless winding?

For motor selection, it is important to know the particular requirements of each application.

  • How large are torque and speed?  Are there any gears involved?
  • How is the motor operated and controlled?  What is the required precision of control?
  • What are the restrictions on size and weight?
  • How about special ambient conditions such as temperature and pressure?

Before answering these questions, the webinar starts with having a look at the properties of all kind of small DC motors with permanent magnets.

  • Which motor designs are adapted for high speed or high torque?
  • How to select motors according to torque and speed requirements
  • What are the particular advantages of brushed or brushless motors?
  • How does a slotted or slotless winding design influence motor performance?
  • What is the role of gears?

The webinar illustrates the findings on a multitude of typical application examples.
