Abstract
Stator structures are fabricated using strip material and moldable magnetic composite, either amorphous metal tape and amorphous flake or similar conventional materials. The laminated core is assembled from identical core sections constructed of nested layers of flat strip, and the moldable material forms the pole pieces after insertion of the coils. Alternately, the pole pieces are produced by bending the laminated tape structure. Shading coils may be added to realize an easily assembled shaded pole motor.
