Electric dynamo

Claim 2

A dynamoelectric machine comprising a shaft, a rotor fixed thereto, a sectional stator having an inner stator and an outer stator, said rotor and shaft rotatably extending into said inner stator and said inner stator having exterior slots, first and second winding support means located at opposite ends of and connected to said inner stator, wire strands extending (a) from and between both of said winding support means and into said inner stator slots and (b) from and between two of said slots at one end of said inner stator and laterally in the form of a chord making contact with two different portions of said first winding support means, said two portions being spaced inwardly from the periphery of said first winding support means and being closer to said shaft than is the inner circumference of said inner stator, and a receiver extending over and in contact with the outer surface of one of said winding support means, said receiver having slots for receiving the ends of said wire strands when the winding thereof is terminated.

Claim 3

A dynamoelectric machine as set forth in claim 1, said first winding support means having an inner ring spaced inwardly from the periphery thereof, the said two different portions of said first winding support means being portions of said inner ring.

Claim 4

A dynamoelectric machine as set forth in claim 2 wherein said first winding support means has a peripheral rim and connector arms joining said inner ring to said peripheral rim.

Claim 5

A dynamoelectric machine as set forth in claim 2 wherein said first winding support means has a hub and said shaft rotatably extends into said hub.

Claim 6

A dynamoelectric machine as set forth iN claim 4 further including connector arms joining said inner ring to said hub.

Claim 7

A dynamoelectric machine as set forth in claim 5 including a peripheral rim disposed outwardly of said inner ring, additional connector arms extending from said inner ring to said peripheral rim, said rim having extension portions extending peripherally outward and having holes therethrough, and connecting rods extending from said inner stator into said holes and connecting said winding support means to said inner stator.

Claim 8

A dynamoelectric machine as set forth in claim 1, said outer stator comprising a plurality of separable sections that collectively embrace said inner stator.

Claim 9

A dynamoelectric machine as set forth in claim 1 wherein said second winding support means has an opening through which said rotor is removable from within said inner stator, and further including a receiver ring on the periphery of said second winding support means having slots to receive the ends of said strands when the winding thereof is terminated.

Claim 10

A dynamoelectric machine comprising a shaft, a rotor assembly fixed to said shaft for rotation therewith, a sectional stator assembly comprising an annular inner stator surrounding said rotor and an outer stator surrounding said inner stator, said shaft and rotor being rotatable relative to said inner stator, said inner stator and said outer stator having mutually confronting outer and inner cylindrical surfaces respectively with a plurality of circumferentially-spaced longitudinally-extending slots formed in the said outer surface of said inner stator, first and second winding supports located at opposite ends of said stator assembly in concentric and spaced relation with said shaft, means connecting each of said winding supports to said inner stator, at least one coil winding for said stator assembly, said coil winding comprising first wire portions that extend along said slots lengthwise of said stator assembly from one to the other of said wire supports and second and third wire portions continuous with said first wire portions that extend laterally of said stator assembly beyond the ends of said rotor in the form of a chord of a circle that is concentric with said shaft and has a circumference which is smaller than the inner circumference of said inner stator, said second and third wire portions being in contact with said first and second winding supports respectively.

Claim 11

A dynamoelectric machine comprising a shaft, a rotor assembly fixed to said shaft for rotation therewith, a sectional stator assembly comprising an annular inner stator surrounding said rotor and an outer stator surrounding said inner stator, said shaft and rotor being rotatable relative to said inner stator, said inner stator and said outer stator having mutually confronting outer and inner cylindrical surfaces respectively with a plurality of circumferentially-spaced longitudinally-extending slots formed in the said outer surface of said inner stator, first and second winding supports located at opposite ends of said stator assembly in concentric and spaced relation with said shaft, means connecting each of said winding supports to said inner stator, at least one coil winding for said stator assembly, said coil winding comprising first wire portions that extend along said slots lengthwise of said stator assembly from one to the other of said wire supports and second and third wire portions continuous with said first wire portions that extend laterally of said stator assembly beyond the ends of said rotor in the form of a chord of a circle that is concentric with said shaft and has a circumference which is smaller than the inner circumference of said inner stator, said second and third wire portions being in contact with said first and second winding supports respectively.
