Abstract
This invention relates in general to dynamoelectric machines, and in particular to a method of fabricating a low cost salient pole stator assembly for a salient pole motor. Low cost salient pole motors are constructed by minimizing stator core stack height or core stack material and maximizing winding slot fill in the motor design process. Thereafter, the windings for the motor design are formed externally of the motor on high speed winding machines and transferred to axial insertion devices. Transfer to the axial insertion devices may be either accomplished automatically or manually. Thereafter, the windings are axially inserted into the stator core. After insertion, the salient pole stator assembly generally is processed like a conventional distributed winding induction motor.
