In part 3 of this case study, Todd Hatfield will be discussing how HECO re-engineered the electrical and mechanical design of the surplus motor to match the 5500HP, 13,200v original motor.
This 13 minute presentation will go over:
- On-site laser measurements using FARO technology
- Determining challenges such as
- How the spare motor would fit into the existing pit
- Configuring an adapter base to fit the new motor
- Creating an identical shaft that could fit into the spare motor
- Duplicating couplings and slip rings
- An Engineering Design Assessment confirming that the spare motor could be redesigned to 5500HP
- The discovery of a series reactor that would put less stress on the whole system
- A Power & Load study of the original motor and application to better understand the load and amperage variation
- Interpreting the Engineering Design Assessment results
Make sure you are all caught up with the series starting with...
