Method of making a rotating electric machine stator core
A method of making a motor stator core having a back iron and a plurality of teeth extending radially inward from the back iron includes providing the plurality of teeth and the back iron from oriented steel so that a magnetic flux transmission path is formed with superior properties in essentially one direction. At least one of the plurality of teeth and the back iron is annealed in selected portions so as to improve magnetic flux transmission in a second direction, different from the one direction.
