Claim Text:
1. A rotary electric machine comprising: a stator extending along an axis and having an outside lamination and a circumferentially spaced series of axially extending discrete teeth secured to the outside lamination with retention features and defining a similar series of circumferentially spaced winding slots therebetween, the retention features preventing inward radial movement of the teeth relative to the stator, and a plurality of stator coils at least partially disposed in each winding slot, each of said stator coils being configured and wound as a concentrated winding, a magnetic flux path between each tooth and the stator being defined by a plurality of cylindrical volumes, each cylindrical volume defining a circular area centered on an axis located at a junction between a surface of the tooth and the outside lamination and a diameter equal to a width of the tooth, wherein each retention feature is substantially located in a region located outside the cylindrical volumes.
