Abstract:
A rotating electric machine comprising a stator having a circular core of a magnetic material and a plurality of magnetic pole teeth extending radially from said circular core, a rotor juxtaposed to the terminal ends of said magnetic pole teeth spaced from said circular core, each of said magnetic pole teeth defining a core and an enlargement formed at the terminal end of said core, to define slots formed between adjacent magnetic pole teeth, each of said slots having a mouth formed between adjacent enlargements, an insulator covering said cores of said magnetic pole teeth, coil windings wound around said cores of said magnetic pole teeth with said insulator being interposed therebetween, each of said insulators having at least one surface inclined relative to a radial plane perpendicular to the rotational axis of said rotating electric machine so that said magnetic pole teeth cores have a differing thickness in an axial direction along their length.
