SEGMENTED STATOR WITH IMPROVED HANDLING AND WINDING CHARACTERISTICS AND CORRESPONDING METHOD

摘要

A stator assembly that may be rounded into an annular form is disclosed that includes a plurality of stator segments where each stator segment defines a yoke portion and a stator tooth and a containment structure configured to position the stator segments relative to one another such that the stator segments do not physically touch one another. Also disclosed is a method for forming a segmented stator, involving the steps of positioning a plurality of stator segment in a containment structure such that no magnetic circuit between adjacent stator segments is formed, forming a winding coil about at least some of the stator segments; and deforming the containment structure to form an annular stator and to establish a magnetic circuit between adjacent stator segments.
