This three and one half day seminar is for specialists and non-specialists who specify, contract, and accept motor or generator repairs and rewinds. Included in the program is material on increasing the capacity of nuclear power plant motors and information on turbine generator rewinding practices. Industry standards (including IEEE, NEMA, and API), insulation materials, processes, coil design and coil manufacturing, stator cores and core testing, rotors, and bearings are all discussed. There is material on motor testing, VPI resins, and tiered motor maintenance. Information is also presented on purchasing new motors. The seminar is held at the facilities of TECO-Westinghouse Motor Company in Round Rock, TX. A tour of this large motor and generator repair and manufacturing facility is included, and TWMC engineers are available for consultation on specific technical issues during the seminar.
What You Will Learn:
Some of the specifics that will be discussed include:

- Develop your own rewind specifications for 480 Volt through 13.2 kV motors and generators using generic specifications
- What insulation system to use for the rewind; insulation system qualification
- Incoming inspection tests, tests during coil manufacture and installation
- Details of coil design and manufacture
- Corona suppression
- How to evaluate the shop’s quality control (QC) program
- The economics of new motor versus rewind
- Epoxy and polyester resins
- How to set up a tiered motor maintenance program
Who Should Attend
Engineers and maintenance personnel from power plants, and industrial users of low voltage and medium-voltage (4 to 13.8 kV) motors and generators, as well motor repair shop personnel, will find this seminar beneficial.
What Is Included
In addition to the presentations and shop tour, lunches are included along with a valuable, annually-upgraded four-volume seminar book.
