Abstract
A stator for a dynamoelectric machine includes an annular stator core composed of a developed core formed by stacking a number of steel sheets, each steel sheet including a plurality of unit cores each of which includes a unit yoke and a magnetic pole tooth and which are sequentially connected together by connecting portions integral with the respective unit yokes, and a stator coil wound on the magnetic pole teeth. Each unit yoke has a circumferential end overlapping, in a direction of stacking of the steel sheets, a circumferential end of the unit yoke adjacent to said each unit yoke.
