Claim 1
Independent Claim
173 words
A dynamoelectric machine comprising: a cylindrical rotor body portion having a plurality of longitudinal slots disposed in its outer surface; an electrical winding cooperatively associated with the rotor body, said winding comprising a plurality of conductors, said conductors including longitudinal portions disposed in said rotor slots and end turn portions connecting said longitudinal portions at both axial ends of the rotor body, said end turn portions extending axially beyond the rotor body; a retaining ring structure joined to each axial end of said rotor body, each retaining ring structure being disposed about the conductor end turn portions to restrain radially outward movement thereof during rotor rotation; two highly conductive mantle structures each having an inner surface and an outer surface, said mantle structures being individually disposed about each of the retaining ring structures such that said inner surface is in intimate electrical contact with said retaining ring; and means for electrically connecting said mantle structure to said rotor surface, said electrical connecting means providing an electrical path separate from said retaining ring structure.
Claim 2
Dependent Claim
173 words
A dynamoelectric machine comprising: a cylindrical rotor body portion having a plurality of longitudinal slots disposed in its outer surface; an electrical winding cooperatively associated with the rotor body, said winding comprising a plurality of conductors, said conductors including longitudinal portions disposed in said rotor slots and end turn portions connecting said longitudinal portions at both axial ends of the rotor body, said end turn portions extending axially beyond the rotor body; a retaining ring structure joined to each axial end of said rotor body, each retaining ring structure being disposed about the conductor end turn portions to restrain radially outward movement thereof during rotor rotation; two highly conductive mantle structures each having an inner surface and an outer surface, said mantle structures being individually disposed about each of the retaining ring structures such that said inner surface is in intimate electrical contact with said retaining ring; and means for electrically connecting said mantle structure to said rotor surface, said electrical connecting means providing an electrical path separate from said retaining ring structure.
Claim 3
Dependent Claim
55 words
The dynamoelectric machine of claim 1, said electrical connection means comprising: a plurality of electrically conductive wedges receivable in said slots for retaining said longitudinal conductor portions within said slots, each of said wedges having an extension which protrudes radially outward, said extension having a radially outer surface which is contactable with said mantle structure.
Claim 4
Dependent Claim
27 words
The dynamoelectric machine of claim 2 wherein said extensions' radially outer surface constitutes a highly electrically conductive material which is softer than said wedges and said mantle.
Claim 5
Dependent Claim
22 words
The dynamoelectric machine of claim 2 wherein said extensions' radially outer surface is contactable with a portion of the mantle's inner surface.
Claim 6
Dependent Claim
19 words
The dynamoelectric machine of claim 4 wherein contact between said wedge extension and said mantle constitutes an interference fit.
Claim 7
Dependent Claim
45 words
The dynamoelectric machine of claim 1 wherein each of said mantle structures includes a radially inward protrusion at the outboard axial ends of each retaining ring structure with each mantle structure's protrusion being in intimate electrical contact with said associated retaining ring's outboard axial end.
Claim 8
Dependent Claim
41 words
The dynamoelectric machine of claim 1 further comprising: a cylindrical support member disposable about each of said mantle structures and in intimate contact with said mantle's outer surface, said support member providing radial retention of said mantle structure during rotor rotation.
Claim 9
Dependent Claim
38 words
The dynamoelectric machine of claim 7 wherein each of said support members constitutes conductive material and has a radial thickness which is less than one depth of electrical current penetration for electrical current induced on the rotor surface.
Claim 10
Dependent Claim
39 words
The dynamoelectric machine of claim 1 wherein each of said mantle structures have a thickness between said inner and outer surfaces of at least one half depth of electrical current penetration for electrical current induced on the rotor surface.
