Abstract
Stator designs have wide-mouth slots between adjacent poles. Wire coils with high slot fill conductivity are formed around the poles. In some designs, the wire coils are wave wound around the poles. Thick bar conductors can be used for making the wire coils. The wire coils may be inserted using nozzle dispensers or transferred from a pre-form mandrel. In other designs, the wire coils are pre-formed on transferable pockets that are then mounted on the poles. Optional pole extensions or shoes can be attached to the stator poles after the wire coils are formed around the poles.
Claims14
A dynamo-electric machine component comprising:
- poles that are geometrically defined by slot passages in a casing, wherein the slot passages have openings between adjoining poles and wherein the openings have widths that are substantially comparable to the widths of the slot passages over their depths;
- and
- wire coils placed around the poles, from directions that are generally along the radii of the dynamo-electric machine component.
11-23. (canceled)
A method for the assembly of a dynamo-electric machine component comprising:
- providing a casing having poles;
- placing wire coils around the poles;
- and,
- then placing pole extensions next to the poles.
26-33. (canceled)
