Case Study 5500HP, 13,200v, Synchronous Motor: (Part 8) Final Assembly and Installation - HECO
July 31, 2019
In the final post in this 8 part case study series, you will see Todd Hatfield explain the final assembly of the 5500HP, 13,200v, synchronous motor in the clip below from a presentation given at the 2018 RPM Symposium.
The presentation below covers:
- Assembling the rotor to the adapter base with the stator
- Using the steel plate made for shipping to also center and pin the rotor, making for a quicker duplication on sight
- Adjusting the exciter to increase the amperage from 80 ADC to 99 ADC
- Removing the original motor and the two adjacent DC exciters
- Installing the motor and doing a test run
- Reinstalling the DC generators to ensure the motor can drive the generators
