The Legacy Servo Drives and Motors We Repair

Customers bring their legacy servo drive and motor repairs to MSI because this is truly where those products get a new lease on life.

There is nothing more satisfying to us than reassuring the owner of a malfunctioning piece of legacy equipment that all hope is not lost. Instead, much to their surprise, we end up showing them through a repair and regular maintenance that there’s a lot of regular use left in that old motor or drive.

Below we have listed all of the legacy servo drives and motors that we repair, so that others might avoid prematurely writing off their equipment.

 What’s Our Secret?

Motor Systems is the only factory-authorized repair center for all Kollmorgen legacy drives and motors. Our technicians have not only been trained by Kollmorgen, they also use the original factory test fixtures and documentation to ensure equipment is restored to its original specs. It also helps that we keep a huge inventory of new and reconditioned boards, as well as hard-to-find parts and reconditioned stock.


Special Note: We are experts with over 25 years of experience repairing Powertec DC Brushless Motors and Drives.
