Abstract
Abstract A method of making stators and armatures for dynamo electric machines in which the customary windings are replaced by extruded inserts seated in circumferentially spaced holes that extend axially through the core of the stator or armature, each of which inserts consists of a group of parallel spaced apart wires embedded in insulating material, the ends of the wires being connected to conductivity paths of printed circuit boards at the axially opposite faces of the core.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
96 words
The method of equipping the cores of dynamo electric machines with electrically connected conductors, which comprises: A. providing rod-like inserts by extruding non-conductive material with a number of parallel spaced apart conductors embedded therein; B. placing said inserts in circumferentially spaced holes that extend axially through the core, with the ends of their conductors exposed; and C. by means of printed circuit boards applied to the axially opposite faces of the core, electrically connecting the exposed ends of embedded conductors of each insert with the exposed ends of embedded conductors of at least one other insert.
Claim 2
Independent Claim
96 words
The method of equipping the cores of dynamo electric machines with electrically connected conductors, which comprises: A. providing rod-like inserts by extruding non-conductive material with a number of parallel spaced apart conductors embedded therein; B. placing said inserts in circumferentially spaced holes that extend axially through the core, with the ends of their conductors exposed; and C. by means of printed circuit boards applied to the axially opposite faces of the core, electrically connecting the exposed ends of embedded conductors of each insert with the exposed ends of embedded conductors of at least one other insert.
Claim 3
Dependent Claim
21 words
The method of claim 1 wherein said rod-like inserts are cut from an extrusion many times longer than the individual inserts.
