Abstract:
A method of assembling a stator comprising:providing a stator frame; connecting a plurality of key bars to said stator frame, each of said key bars having a dovetail; and forming a stator core including: forming a pre-packed stator core section including at least one first lamination having a first dovetail slot; coupling said pre-packed stator section to said stator frame by engaging a first one of said dovetails into said first dovetail slot; forming at least one second lamination having a second dovetail slot; and coupling said second lamination to said stator frame by manually stacking said second lamination such that a second one of said dovetails engages into said second dovetail slot to form a manually stacked stator core section; wherein said first and second dovetail slots are formed such that a cross-sectional area of said first dovetail slot is larger than a cross-sectional area of said second dovetail slot.
