Abstract

An apparatus for manufacturing stators of dynamoelectric machines, the stators being formed as an assembly of pole segments; the apparatus comprising a seat where the assembly of pole segments are seated. An engagement assembly engages first ends of the pole segments for translation of the pole segments from the seat to a transfer device. A first holding assembly comprises a first plurality of holding members for clamping the pole segments to hold the pole segments as an assembly of pole segments. The first holding assembly being arranged on the transfer device moveable to transfer the assembly of pole segments from a first position to a second position. A containing assembly is located at the second position and provided with a second plurality of holding members for holding the assembly of pole segments. The second plurality of holding members are positioned on the containing assembly to surround the assembly of pole segments that are located at the containing assembly.

First claim

1 - 16 . (canceled)

17 . A method for manufacturing stators of dynamoelectric machines, the stators being formed as an assembly of pole segments, the method comprising:
seating the assembly of the pole segments in a seat; engaging first ends of the pole segments for translation of the pole segments from the seat to a transfer device; clamping the pole segments with a first plurality of holding members ( 201 , 202 , 203 ) of the transfer device to hold the pole segments as an assembly of pole segments; moving the transfer device to transfer the assembly of pole segments from a first position to a second position; providing a casing assembly at the second position; and providing the casing assembly with a second holding assembly comprising a second plurality of holding members ( 311 , 312 ) for holding the assembly of pole segments; the second holding assembly being positioned on the casing assembly for maintaining the assembly of pole segments in a predetermined position when the pole segments are located at the casing assembly.

18 . The method of claim 17 further comprising engaging ends of the pole segments against a reference surface to align the ends of the pole segments.

19 . The method of claim 18 further comprising using a plurality of engagement members and engaging each engaging member with a specific pole segment to move the pole segments towards the reference surface.

20 . The method of claim 17 further comprising providing the assembly of pole segments with a support member having terminals for connection of leads of coils of the pole segments; and pushing on the support member to maintain the support member in a constant position with respect to the assembly of pole segments.

21 . The method of claim 17 further comprising providing the casing assembly with a third holding assembly comprising a third plurality of holding members for holding a support member, and arranging the third plurality of holding members to be surrounded by the second plurality of holding members ( 311 , 312 ).

22 . The method of claim 17 further comprising rotating or translating the casing assembly to a further position.

23 . The method of claim 17 further comprising arranging engaging means to push leads of coils of pole segments into predetermined positions of terminals of the assembly of pole segments.

24 . The method of claim 17 further comprising crimping the terminals around the leads of coils.

25 . The method of claim 17 further comprising fusing the leads of coils to terminals.
