Servo Motor Repair Department

Servo motors are now an everyday occurrence in automated processes where precise control and positioning along with high torque are required. Much is written about their features and capabilities but not so much about their maintenance and repair.

Built with similar parts as a conventional AC motor (stator winding, shaft, bearings and an end shield) what sets servos apart is the incorporation of an integral ‘feedback’ device. This device takes the form of an encoder or a resolver and works with the controller to ensure that the motor can be programmed to perform very complex tasks such as accurate positioning, rapid changes in speed and even maintain a static position while maintaining a certain level of torque.

It is imperative that the ‘programming and set up’ of these devices is integrated into the repair process. This can only be done using software which is specific to the make and model of the servo motor, without which the servo motor simply will not work.

We make regular investments to ensure that we have a broad range of updated test facilities that reflect our customer’s service commitments. CPM Servolab – our dedicated servo motor repair department – have now completed the investment in:

  • Upgrading the Feedback testing System;
  • New department layout;
  • New Test Rigs.

With the plethora of manufacturers around the world this means any repair organisation not only needs to have an exhaustive library of these software programmes but also must have the capability to keep abreast of new motors which come to market.

Returning servo motors to the Original Equipment Manufacturer is not always an option due to obsolescence, price or expensive lead times. Only a specialist servo motor repairer such as CPM ServoLab – who have repaired over 7,000 servo motors by specifically trained personnel, with ISO 9000 repair specifications and a library of over one hundred software programmes – can offer a fast turnaround and guaranteed quality at a much lower cost.
