Abstract
A stator frame comprises a connection end (CE) casting having at least one CE integral partial tie bar extending from an inboard side of the CE casting and a pinion end (PE) casting having at least one PE integral partial tie bar extending from an inboard side of the PE casting. Each PE partial tie bar is welded to a respective CE partial tie bar.
Claims5
A stator comprising:
- a connection end (CE) casting including at least one CE integral partial tie bar extending from an inboard side of the CE casting;
- a pinion end (PE) casting including at least one PE integral partial tie bar extending from an inboard side of the PE casting, each of the at least one CE and PE partial tie bars having a grooved surface therein for holding material used for welding in the area of a weld and an undercut on an opposite slide of each respective grooved surface;
- and
- a plurality of stator laminations in the CE and PE castings, the at least one PE partial tie bar being welded to the at least one CE partial tie bar and a high temperature material in each undercut separating the stator laminations from the material used for welding.
