Case Study 5500HP, 13,200v, Synchronous Motor: (Part 1) Problem Identification & Potential Solution

07/09/2019

Blog 1 imageThe video below is a segment from an hour long presentation given by Todd Hatfield, Senior Electrical Engineer at HECO - All Systems Go, at the 2018 Reliability, Process, and Maintenance (RPM) Symposium.  

This is the first of an 8 part article series that will be coming out twice a week over a 4 week period. Each post will cover different points of the case, leading up to the final assembly and installation. Be sure to check out this article on how Synchronous Motors work before starting the series!

 The presentation below discusses:

  • The two 5500HP identical synchronous motors that were in need of significant repairs
  • The decision between waiting for a new motor vs. using a spare to replace the original motors in order to rebuild them 
  • The process of repairing motors with the use of reverse engineering 
  • The nameplate comparison between the original motor and HECO's potential solution motor
