Case Study 5500HP, 13,200v, Synchronous Motor: (Part 3) Electrical & Mechanical Redesign Engineering - HECO

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…

• • What is an AC Synchronous Motor?
  • Part 1 – Problem Identification and Potential Solution
  • Part 2 – Evaluating Surplus Motor Option and Initial On-site Application
