Stator Winding & Assembly

Ramco Electric Motors, Inc. winds stator coils and builds stator assemblies to your design for motors from fractional HP to 200HP and up. We hand-insert both lap and concentric wound coils for single, three phase power AC Induction stators, as well as DC brushless stators. Every one of our stators is wound, assembled, and tested by an experienced technician.

Stator Secondary Operations:

  • Stator Shell Flat Rolling and Welding
  • Stator Varnish Impregnation - Dip & Bake
  • Stator Varnish Impregnation - Vacuum Pressure Impregnation (VPI)
  • Stator ID Honing and ID Varnish Cleaning
  • Stator OD Machining or Grinding
