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

07/29/2019

5500HP stator and adaptor base-1For 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
