Method for production of supporting basket for an end winding
View Patent ↗A method for the production of a supporting basket ( 1 ) for an end winding of a stator winding of an electrical machine includes preassembling the supporting basket ( 1 ), mounting electrically insulated round connectors ( 6 ) on the supporting basket ( 1 ), immersing the supporting basket ( 1 ) with the mounted round connectors ( 6 ) in an impregnation agent bath ( 12 ), evacuating the impregnation agent bath ( 12 ), and removing the supporting basket ( 1 ) with the mounted round connectors ( 6 ) from the impregnation agent bath ( 12 ), and drying, curing, or both, the impregnation.
1. A method for production of a supporting basket for an end winding of a stator winding of an electrical machine, the method comprising:
preassembling the supporting basket;
mounting electrically insulated round connectors on the supporting basket;
immersing the supporting basket with the mounted round connectors in an impregnation agent bath;
evacuating the impregnation agent bath;
removing the supporting basket with the mounted round connectors from the impregnation agent bath;
curing, drying, or both, an impregnation formed on the supporting basket with the mounted round connectors; and
mounting the supporting basket with the round connectors on a stator, after said curing, drying, or both.
2. The method as claimed in claim 1 , further comprising:
producing the stator winding for the supporting basket, the stator winding including winding bar end sections which form an end winding of the stator winding; and
connecting winding bar end sections to the round connectors.
3. The method as claimed in claim 1 , wherein mounting electrically insulated round connectors comprises mounting on the exterior of the supporting basket.
