Filed:

Jun 24, 2004

Appl. No.:

10/875423

Inventors:

David Shore - Gastonia NC, US
Phillip Keaton - Rock Hill SC, US

Assignee:

Siemens Power Generation, Inc. - Orlando FL

International Classification:

H02K 11/00
H02K 3/00
H02K 1/00
H02K 1/22
H02K 3/46

US Classification:

310179, 310 71, 310261, 310270

Abstract:

A generator includes a shaft and rotor body defining poles and a winding positioned around the shaft on the rotor body. A rotor pole crossover is aligned to the shaft and connects ends of the winding between adjacent poles. The rotor pole crossover includes a body member having a curved medial section and opposing legs extending outwardly from the curved medial section that connect to the ends of the winding. The curved medial section has at least one slot formed therein to add flexibility to the rotor pole crossover.

Assignee:

Siemens Energy, Inc. - Orlando FL

International Classification:

H02K 11/00

US Classification:

310 71, 310270

Abstract:

An electric machine includes a shaft and a rotor carried by the shaft and having a rotor body, a plurality of rotor windings carried by the rotor body, and a retaining ring surrounding the rotor windings adjacent an end of the rotor body. An electrically conductive stud extends radially outwardly from the shaft adjacent the end of the rotor body. An electrically conductive member includes a first end section coupled to the electrically conductive stud and having a loop shape, a second end section coupled to a corresponding one of the rotor windings, and an intermediate section between the first and second end sections. An insulation assembly is between the shaft and the retaining ring and surrounding the intermediate section to define at least one gap with adjacent portions thereof.
