Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
189 words
An insulated pole and coil assembly for a dynamoelectric machine, said assembly comprising a pole member having a base portion and two tip portions that protrude respectively from opposite sides of said base portion, a coil of insulated magnet wire having a central opening formed therein and fitted closely around said pole base portion, a plurality of formed sheets of insulating material each including a back part and a lip part, each of said sheets being positioned with its back part extending around and a predetermined distance beyond a respective corner of said pole base portion with the lip parts of the respective sheets facing and conforming closely to the adjacent coil surface and the respective surfaces of the pole tip portions that are juxtaposed with said coil, thereby to insulate the coil from the pole member by positioning the ends of each of said sheets in overlapping relationship with the ends of adjacent sheets and to cover all of the sides and corners of said pole base portion that are surrounded by said coil and to cover the surfaces of said pole tip portions closest to said coil.
Claim 2
Dependent Claim
189 words
An insulated pole and coil assembly for a dynamoelectric machine, said assembly comprising a pole member having a base portion and two tip portions that protrude respectively from opposite sides of said base portion, a coil of insulated magnet wire having a central opening formed therein and fitted closely around said pole base portion, a plurality of formed sheets of insulating material each including a back part and a lip part, each of said sheets being positioned with its back part extending around and a predetermined distance beyond a respective corner of said pole base portion with the lip parts of the respective sheets facing and conforming closely to the adjacent coil surface and the respective surfaces of the pole tip portions that are juxtaposed with said coil, thereby to insulate the coil from the pole member by positioning the ends of each of said sheets in overlapping relationship with the ends of adjacent sheets and to cover all of the sides and corners of said pole base portion that are surrounded by said coil and to cover the surfaces of said pole tip portions closest to said coil.
Claim 3
Dependent Claim
44 words
An invention as defined in claim 1 in combination with a rigid body of thermally conductive dielectric material positioned between said coil and pole base portion along a predetermined side of said insulating sheets thereby to improve thermal conduction between the pole and coil.
Claim 4
Dependent Claim
58 words
An invention as defined in claim 2 wherein the respective sides of each of said sheets extending beyond an adjacent corner of said pole member have different lengths and its longer side is disposed at approximately 90° to the shorter side of the sheet to define a generally L-shaped configuration around a corner of said pole base portion.
Claim 5
Dependent Claim
78 words
An invention as defined in claim 3 wherein the back and lip parts of each of said sheets are positioned about 90° to one another and the lip part of each of said sheets comprises a first section co-extensive in length with said shorter side of the sheet, a second section co-extensive in length with the longer side of said sheet and a third section formed to define a corner that extends between said first and second sections.
Claim 6
Dependent Claim
50 words
An invention as defined in claim 4 wherein said back part and the first and second lip sections of each sheet are formed of a single sheet of insulating paper, and the third section of the lip part of each sheet is formed of a separate piece of insulating material.
Claim 7
Dependent Claim
40 words
An invention as defined in claim 5 wherein each of said separate pieces of insulating material respectively forming the third sections of the lip parts of said insulating sheets comprises a sheet of felt material impregnated with thermo-setting insulating resin.
Claim 8
Dependent Claim
47 words
An invention as defined in claim 6 wherein each of said third sections of the respective lip parts of said formed sheets of insulating material is positioned to overlap a predetermined portion of the ends of the first and second sections of the lip part adjacent thereto.
Claim 9
Dependent Claim
45 words
An invention as defined in claim 7 wherein each third section of the respective lip parts of said formed sheets of insulating material is positioned to overlap a predetermined portion of the back part of said sheet of insulating material adjacent to said third section.
Claim 10
Dependent Claim
81 words
An invention as defined in claim 8 wherein the predetermined portions of said first and second lip sections that are overlapped by said third lip section include about 1/4 inch of the respective ends of said first and second sections and said predetermined portion of the back part overlapped by said third section of the lip part extends about 1/4 inch in all directions from the intersection of the corner defined by said first and second sections of the lip part.
