Abstract A method of forming a stator assembly for a dynamoelectric machine includes the steps of forming a continuous metal strip with stator slots along one peripheral edge and gear teeth along the other peripheral edge and then using a gear wheel engaging the gear teeth to drive the strip onto a former to coil the strip helically. In a modification, in order to produce a yoke or a stator assembly for a dynamoelectric machine a continuous metal strip is formed with gear teeth along one peripheral edge thereof and a gear wheel is engaged with the gear teeth and drives the strip onto a former to coil the strip helically to produce the yoke or stator assembly. The gear teeth in the strip can be the stator slots where a stator assembly is to be produced, or can be specially provided gear teeth where a yoke assembly is to be produced.
A method of forming a stator assembly for a dynamoelectric machine the assembly being of the kind including a laminated member in the form of a helically coiled metal strip, comprising, forming a continuous metal strip with stator slots along one peripheral edge of the strip, and gear teeth along the other peripheral edge of the strip, the formation of the gear teeth serving to relieve one edge of the strip to facilitate coiling of the strip, engaging a gear wheel with said gear teeth, and, rotating said gear wheel so as to drive said strip into a former, the shape of the former being such that as the strip is driven into the former, the strip coils in a helical manner.

Claim 3
Dependent Claim
58 words
A method as claimed in claim 1 including the steps of severing the helically coiled strip from the remaining strip, engaging a tool with the gear teeth of the helically coiled strip to align the stator slots of the coiled strip and then treating the coiled strip to retain the strip in position with the stator slots aligned.
Claim 4
Dependent Claim
30 words
A method as claimed in claim 2 wherein said coiled strip is soldered along dwells between its gear teeth to retain the strip in position with the stator slots aligned.
