Rexroth Servo Motor Repair
Rexroth servo motors can be complex and difficult to repair. Most of the challenge is derived from the multitudes of feedback found on these motors. Servotech has the ability to test, repair, and replace just about any Rexroth feedback device – including encoders, resolvers, halls and tachometer assemblies. Despite the obstacles these motors can present, Rexroth is a manufacturer that we are proud to service.
Our AC servo motor repair technicians are highly skilled and experienced, and they know how to properly test the motors without corrupting the stored data on encoders or memory boards. Mechanical considerations receive just as much attention – checking bearing fits, housing fits, and inspecting for worn output shafts are just a few of the things we look for when evaluating a Rexroth AC servo motor.
Our team has all the necessary tools, parts and resources to refurbish Rexroth servo motors back to good-as-new condition. We are proud to offer the highest quality servo motor repairs in industry-leading turnaround times to get you up and running as quickly as possible.
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 Rexroth 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 Rexroth 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 Rexroth 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 Rexroth 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
