Abstract
The invention provides a stator for a dynamo-electric machine capable of preventing deterioration of efficiency. In the stator for dynamo-electric machine of which rotor is disposed inside the stator, a stator corecomprises: an inside ring coreformed annularly by laminating plate-type magnetic members in which a plurality of teeth are provided on one side of a yoke portion, disposing coilsin slots each formed between the teeth, bending the plate-type magnetic members so that the coilsare located inside, and bringing two end faces into contact with each other; and an outside ring core, being made of magnetic members and formed cylindrical in shape, which is fitted on outside of the inside ringand holds the inside ring core
