Allen-Bradley Servo Motor Repair
Allen-Bradley AC servo motors are subjected to an in-depth evaluation once they arrive at our facility. Our goal is to provide you with the highest quality servo motor repair and to return your motor in good-as-new condition. Our AC servo motor repair technicians thoroughly inspect all mechanical and electrical components of the motor to ensure that anything not up to spec is addressed, treating the motor as a whole rather than only fixing what is broken.
To become effective at repairing these motors, we have established a good working relationship with Sick Stegmann, the manufacturer of encoders that appear on a majority of Allen-Bradley servo motor models, particularly the MP-series. Servotech is a stocking distributor of these encoders and has full programming capabilities. Non-programmed or improperly programmed encoders will not work when run on factory drives. Once a newly programmed encoder is installed and repairs are complete, we test the motor on factory drives to ensure your motor will function properly once returned to you.
Allen-Bradley DC Servo Motor Repair
Each Allen-Bradley DC servo motor that enters our shop will go through an extensive evaluation to determine the cause of failure. Our DC servo motor repair technicians know the motors inside and out and have the experience and knowledge necessary to properly test and repair them. Every part of the motor is meticulously inspected, checking all mechanical and electrical components throughout. Our goal is to extend the life of your brushed DC servo motor, returning it to you in good-as-new condition.
DC servo motors contain carbon brushes, which are necessary for the motor to function. These brushes will wear out over time, and with nowhere for the carbon dust to go, the motor itself can become contaminated throughout. When you send your motor to Servotech, you can trust that the entire motor will be thoroughly cleaned and brand new brushes will be installed.
Since these motors are no longer considered current technology, parts can become obsolete and hard to find. Servotech takes pride in maintaining an extensive inventory of replacement parts for these servo motors. When parts cannot be sourced, we do everything we can to come up with a compatible replacement, even if we have to fabricate it ourselves. Our in-house machine shop and 3D printing capabilities make it possible for us to reverse engineer and fabricate parts such as endbells, encoder covers, connector blocks and more. When it comes to repairing Allen-Bradley DC servo motors, there is no team more capable and well-equipped than Servotech.
In addition to Allen Bradley servo motor repair services, Servotech refurbishes servo and spindle motors from over 100 manufacturers, click to view all brands we service.
Our Repair & Refurbishment Process
1. Checking In
- Motor is photographed and documented by our receiving department
- Unique job number is assigned
- Acknowledgement is sent via email
- Motor is delivered to the appropriate department to be evaluated
2. Evaluation
The evaluation of each Allen-Bradley servo motor is extremely thorough and is 100% free for all our customers. Our technicians fully inspect all mechanical and electrical parts. They also perform multiple tests to determine the cause of failure. This includes, but is not limited to:
- Bearing fits
- Housing fits
- Worn output shafts
- Corroded and/or broken flanges
- Burnt Stator Windings
- Failed Encoders
- Damaged Connectors
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.
4. Servo Motor Repair
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 Allen-Bradley servo 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 Allen-Bradley 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 Allen-Bradley 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..
- Bearing fits
- Housing fits
- Worn output shafts
- Corroded and/or broken flanges
