Expanded content!  At the request of last year’s attendees, this course has been expanded to a full-day. In addition to more time spent at each failure analysis station, content regarding lubrication of electric motors and case studies have been added. 

We are going to help answer the question: What can a reliability engineer expect from a motor repair facility?

Well, it is pretty basic, how you treat your motor determines the life of it. When it is time to repair it, do you send it out with minimum standards in place for its performance upon return?

This workshop will cover the infrastructure (teardown, core loss testing before and after burnout, rewinding, shaft balancing, re-assembly) of a motor shop, including the integration of a motor shop’s work practices and the motor autopsy results method of communication back into your reliability program using Reliability Data Management.

For most motor repairs, any craftsmanship problems will show up in the first 30 days of an installation of a new or repaired motor. If properly installed by field services performing precision balancing and hot alignment, thermography on the electrical connections and mechanical condition evaluated through vibration monitoring, the returned and installed unit may have higher quality and even better efficiency than when the motor arrived at the shop.

The extended field services most shops offer include periodic (monthly or quarterly) vibration testing, yearly infrared, alignment and electrical testing performed on the motor, and a good lubrication program. If you have these technologies and programs deployed, motor repair facilities should be able to offer an extended warranty on the motor. Does your motor shop offer the standard one-year warranty, or an extended warranty? That would be good to know!

This workshop will be held at Tekwell Services in downtown Knoxville. Tekwell is a SKF-Certified Repair Shop, one of about 50 in the entire United States. The workshop will include activities at four of the major repair stations in the Tekwell facility, led by shop floor personnel. This is a great opportunity to ask questions and learn about best practices in the motor repair process.
