Servo motors can be used in a range of applications, and like any component, will wear over time. Understanding how to test and repair them can ensure longevity of the servo motors themselves as well as reduce downtime for the machines into which they are integrated.

I spoke with Stuart Mitchell, Vice President of Mitchell Electronics Inc., about testing and repair of servo motors. Mitchell Electronics develops test products for encoders and servo motors, serving industries in which brushless servo motors often fail or require more regular maintenance and troubleshooting due to heavy use or extreme environmental conditions. This includes manufacturing industries such as automotive, aerospace, food services, consumer packaged goods, and robotics.

Mitchell offers his insight into common causes of servo motor malfunctions as well as how best to test and repair motors to help maintain productivity.
