Todd A. Hatfield - Vice President of Engineering & Repair, HECO
This is an electric motor repair case study on a 800HP, 900RPM, 4000V Coal Crusher Motor for a Midwest-US based coal fired power generation plant. In 2006 the utility came to HECO after years of repetitive failures circling around the electric motor's rotor. This was originally presented at the Reliability, Process, and Maintenance (RPM) Symposium on Sep 13-14, 2016.
