ABSTRACT:
A method of manufacturing a dynamo electric machine stator assembly of the kind which includes a hollow cylindrical yoke defining internally a plurality of poles, and a sinusoidal field winding extending around the poles. The method includes the steps of inserting a reduced diameter winding into the yoke with the axial portions of the winding aligned with the spaces between the adjacent pairs of poles. The winding is then expanded radially to engage the axial portions between the respective poles and finally the winding is secured in position by subjecting the winding to a compressive loading in an axial direction. Care is taken to ensure that the winding does not collapse radially inwardly and the magnitude of the axial loading applied to the winding is sufficient to cause initial elastic deformation of the winding into contact with the poles and the inner surface of the yoke, and then subsequently plastic deformation of the winding whereby upon release of the axial loading the winding remains in its deformed configuration.
