Case Study 5500HP, 13,200v, Synchronous Motor: (Part 7) Adapter Base - HECO

July 29, 2019

For part 7 of this series, Todd Hatfield will be explaining the process of creating the adapter base in the 2 videos below. Video one explains the engineering of the adapter base design, while the second video explains the process of mounting the stator to the adapter base.

Video 1 describes:

  • Creating a CAD drawing to ensure the adapter base design was scaled to fit into the concrete pit
  • Taking the designs to a fabricator to create the base with additional support
  • The stress relief process that was performed to relieve the stress the heat from welding produced
  • Sending the adapter base to a boring mill so they could machine the surfaces to the tolerances we provided

Video 2 explains:

  • Fitting the stator into the adapter base and welding the bolts to keep it in place
  • Determining where to brace the floor to put gussets in order to stabilize the base

With one post left in the series, make sure you are all caught up starting with…
