Manufacturing system and method of manufacture for stator assembly of rotary system
A method of manufacturing a stator assembly for an electrified rotary system includes attaching a first tooth and a second tooth to an inner support to define a first construction. The first tooth and the second tooth extend radially away from the inner support in the first construction. The method also includes attaching a winding about the first tooth of the first construction to define a second construction. Furthermore, the method includes applying, with a fixture, a preload at a joint between the inner support and the first tooth of the second construction. Moreover, the method includes attaching an outer support to a first outer radial end of the first tooth and to a second outer radial end of the second tooth while applying the preload to define a third construction.
