Yaskawa AC Servo Motor Repair
Through years of experience, Servotech has built a solid relationship with the Yaskawa factory. Because of this, we have the necessary resources to repair your motor to it’s factory specifications. Between our years of experience working on these motors and our access to factory datasheets and technical information, there is no one better to handle your Yaskawa AC servo motor repair than Servotech.
Most Yaskawa AC servo motors utilize a feedback device that needs to be programmed at the factory. Our purchasing team works very closely with the factory to ensure speedy processing when replacing a programmed encoder. In addition to this, we stock already programmed encoders for the most commonly seen models. If you are in a pinch and need a Yaskawa servo motor repaired fast, there is a very good chance that we will have everything needed right on our shelf.
It is critical that these motors are tested properly on factory drives as opposed to generic ones. This is the only way to ensure that the motor will run as it should once installed in the machine. Servotech possesses the same factory drives that our customers do – and we use them to final test every Yaskawa motor before it leaves our shop.
Yaskawa DC Servo Motor Repair
Yaskawa DC servo motors present a unique set of challenges when it comes to repair. Our DC servo motor repair technicians are experts at diagnosing these motors and have decades of experience working with them. Once at our facility, the motors go through an extensive evaluation, with all electrical and mechanical components inspected meticulously. We will not only determine the cause of failure, but we look for any worn parts that could cause failure down the road.
One main issue we are presented with when repairing these motors is the obsolete feedback devices. Servotech has gone the extra mile to reverse engineer replacement encoders that are no longer available from the factory. The replacement encoder will function just as the original one did once the motor is installed in the machine. We verify this by final testing each motor on the same Yaskawa factory drives used in our customers machines.
Thanks to our relationship with the Yaskawa factory, we have obtained a vast library of technical documentation which allows us to compare every motor to factory specifications. This combined with the expertise and wisdom of our technicians means we can offer the highest quality refurbishment at an industry-leading turnaround time. When it comes to Yaskawa DC servo motor repair, there is nobody more qualified than the Servotech team.
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 Yaskawa 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 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 Yaskawa 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 Yaskawa 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
