Abstract:
A method of forming a stator in a dynamo electrical machine comprising the steps of:a. arranging a cylindrical jig that has an outside diameter corresponding to an inside diameter of a rotor opening of the stator; b. mounting inner edges of stator teeth on the jig to form a circular array of teeth, where the teeth extend radially out from the jig; c. sliding a first separator bar into an axial end of a stator slot defined between adjacent stator teeth, where the separator bar has a lower surface adjacent the jig and an upper surface; d. seating a cable winding on the upper surface of the first separator bar by inserting the cable winding radially into the stator slot; e. sliding a second separator bar axially into the stator slot and over the seated cable winding, where the second separator bar has a lower surface seating on the already seated cable winding, and has an upper surface to seat another cable winding; f. repeating steps (d) and (e) until a sequence of separator bars and cable windings are stacked in the stator slot.
