ABSTRACT:
A stator assembly for a dynamoelectric machine has a yoke member formed of a continuous strip of ferro-magnetic material with a generally cylindric inner surface. A plurality of spaced teeth are provided extending axially along and inwardly from the inner surface of the yoke member and having inner ends which define a bore for receiving a rotor member. Each of the teeth includes a plurality of axially and inwardly extending ferro-magnetic flat segments of ferro-magnetic strip material and connecting portions respectively positioned between adjacent ones of the teeth. Each of the connecting portions is formed of a ferro-magnetic strip material and has leg elements which respectively form parts of the adjacent ones of the teeth and a connecting element which extends between the leg elements.
