Kollmorgen AC Motors Kollmorgen DC Motors
Kollmorgen servo motors require careful evaluation. By thoroughly testing your motors, we make sure your old, broken down Kollmorgen servo motor can be refurbished back to the “factory new” standard. In order to properly repair your Kollmorgen servo motor it is vital to have a good working relationship with the factory. By liaising with Kollmorgen we are able to procure original technical documents and finite specifications for the servo motor. Without this information, a motor can only be repaired to “running” condition. Using this information ensures your motor will perform to its factory specifications in your machine. Our goal is to give you a Kollmorgen servo motor that is not only repaired but has been refurbished back to like new condition.
Kollmorgen AC Servo Motor Repair
Kollmorgen AC Servo Motors require a careful, thorough evaluation to determine the cause of failure. Our AC servo motor repair technicians have decades of experience working with these motors and possess all the tools needed to properly diagnose them.
By maintaining a good relationship with the factory, Servotech has acquired a vast library of technical documentation. This is crucial because it allows us to ensure that each motor meets or exceeds factory specifications once repaired. Other repair shops may repair a motor to “running” condition, but with Servotech, you can trust that your motor will be returned to you good as new.
While repairing your servo motor correctly is important, we understand that time is also critical. To minimize downtime for our customers, we maintain an extensive inventory of replacement parts such as bearings, connectors, and feedback devices. This combined with our in-house capabilities such as stator winding and machining allows us to refurbish your motor and get it back to you in record time.
Kollmorgen DC Servo Motor Repair
When it comes to repairing Kollmorgen DC servo motors, there is no team more qualified and knowledgeable than Servotech. Our DC servo motor repair technicians know how to properly inspect these motors electrically and mechanically, identifying the cause of failure. Our vast library of technical documentation combined with our extensive inventory of replacement parts means we can provide the highest quality refurbishment with an industry leading turnaround time.
Kollmorgen also makes pancake motors, also called PMI or disc motors. These motors present a unique set of challenges when it comes to repairing them. They are equipped with thin, disc-shaped armatures and powerful permanent magnet field frames. Our technicians are able to re-magnetize the field magnets with a charge fixture – something that not all repair shops are capable of doing.
Whether you have a conventional Kollmorgen DC servo motor or a disc motor, you can trust that it will be in good hands when you send it to Servotech. We take pride in offering the absolute highest quality refurbishment possible, with an industry-leading turnaround time to get you up and running quickly.

3. Quote
Our purchasing department then generates a firm quote, outlining the cause for failure, and listing all needed parts for repair. Our team excels in sourcing any parts that are not already stocked in our extensive inventory. We understand that getting your machine up and running is of utmost importance, and we go above and beyond to offer you the quickest delivery possible.

Once the quote is approved, orders are placed for any needed parts and our technicians proceed with repairs. Anything that requires our in-house services, such as winding or machine work, is taken to the corresponding department. When ready, the motor is re-assembled with all new parts and hardware, bringing it to good-as-new condition.
5. Final Testing
Upon completion of repairs, the motor heads to our quality control department for final testing. Here, we review the entire repair and run it on a factory specific drive. Using the same drive that is used in your machine ensures that your Kollmorgen servo motor will run just as it should once re-installed. We take great pride in maintaining an inventory of factory drives as it allows us to offer the most effective, reliable refurbishment possible.
6. Painting & Re-Labeling
Not only does a fresh coat of paint make your Kollmorgen servo motor look brand new, but it also provides protection from outside contaminants, extending the overall lifespan of the motor. Our painting department provides application-specific paint, such as:
- Food grade epoxy
- IP67 epoxy
- Marine epoxy
7. Return Shipping
Our shipping department takes pride in offering the highest quality care when preparing a refurbished motor for its journey back to you. Protective caps are put on connectors, nameplates are applied to the motor, and documentation is reviewed to make sure any accessories, such as eye bolts or shaft keys, are returned to you. Our high-quality spray foam packaging system creates a mold around the motor to keep it safe in the box during shipping. For larger motors that require freight shipping, we build a custom crate on-site to fit each motor’s unique size and shape..
