Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a stepped portion, and an array of conductors disposed in a spaced relationship on said step portion and extending longitudinally and radially outwardly from said step portion, a sleeve disposed over said array of conductors, a flattened tubular member disposed radially inwardly of the conductors, and means for retaining said conductors in a spaced relationship, whereby additional space is provided for said conductors and for cooling them.
Claim 2
Dependent Claim
79 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a stepped portion, and an array of conductors disposed in a spaced relationship on said step portion and extending longitudinally and radially outwardly from said step portion, a sleeve disposed over said array of conductors, a flattened tubular member disposed radially inwardly of the conductors, and means for retaining said conductors in a spaced relationship, whereby additional space is provided for said conductors and for cooling them.
Claim 3
Dependent Claim
29 words
A rotor as set forth in claim 1, wherein the tubular member has pressurized fluid disposed therein for expanding the tubular member and biasing the conductor toward the sleeve.
Claim 4
Dependent Claim
90 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a stepped portion, an array of conductors disposed in a spaced relationship on said stepped portion and extending longitudinally and radially outwardly from said stepped portion, a sleeve disposed over said array of conductors, a plurality of spaced apart longitudinal grooves in the step portion of the shaft, the grooves being sufficiently deep to align the conductors, and means for biasing the conductors toward the sleeve, whereby additional space is provided for said conductors and for cooling them.
Claim 5
Dependent Claim
90 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a stepped portion, an array of conductors disposed in a spaced relationship on said stepped portion and extending longitudinally and radially outwardly from said stepped portion, a sleeve disposed over said array of conductors, a plurality of spaced apart longitudinal grooves in the step portion of the shaft, the grooves being sufficiently deep to align the conductors, and means for biasing the conductors toward the sleeve, whereby additional space is provided for said conductors and for cooling them.
Claim 6
Dependent Claim
76 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a step portion, an array of conductors disposed in a spaced relationship on said stepped portion and extending longitudinally and radially outwardly from said stepped portion, a sleeve disposed over said array of conductors, means for retaining said conductors in a spaced relationship, and means for biasing the conductors toward the sleeve, whereby additional space is provided for said conductors and for cooling them.
Claim 7
Dependent Claim
76 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a step portion, an array of conductors disposed in a spaced relationship on said stepped portion and extending longitudinally and radially outwardly from said stepped portion, a sleeve disposed over said array of conductors, means for retaining said conductors in a spaced relationship, and means for biasing the conductors toward the sleeve, whereby additional space is provided for said conductors and for cooling them.
Claim 8
Dependent Claim
74 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a step portion, an array of conductors disposed in a spaced relationship on said step portion and extending longitudinally and radially outwardly from said step portion, a sleeve formed from a graphite epoxy composite disposed over said array of conductors and means for retaining said conductors in a spaced relationship, whereby additional space is provided for said conductors and for cooling them.
Claim 9
Dependent Claim
74 words
A rotor for a dynamoelectric machine, said rotor comprising a shaft having a step portion, an array of conductors disposed in a spaced relationship on said step portion and extending longitudinally and radially outwardly from said step portion, a sleeve formed from a graphite epoxy composite disposed over said array of conductors and means for retaining said conductors in a spaced relationship, whereby additional space is provided for said conductors and for cooling them.
