1. A method for creating a stator for an electro-mechanical transducer from a plurality of segments, said segments having an axially elongated body having a radial outer portion and a radial inner tooth portion and at least one half of a tooth, said radial outer portion being circumferentially wider than said radial inner tooth portion so that when a plurality of said segments are positioned in an annular configuration an axially extending radial side portion of each segment will contact an axially extending radial side portion of the adjacent segment on each side to form a return path, said return path having a plurality of teeth projecting radially inwardly therefrom, said method comprising:

  • aligning said plurality of segments linearly whereby a single row of teeth is created;

    winding said linearly aligned teeth to create an armature winding;

    circumferentially positioning the segments to create a circumferential structure, said teeth of said circumferentially positioned segments pointing radially inwardly; and

    fitting an annulus about the outer diameter of the circumferentially positioned segments in an interference fit to maintain the segments circumferentially.
