ABSTRACT:
A stator for a dynamoelectric machine includes an annular stator core in which a large number of slots extending in an axial direction are disposed in a circumferential direction so as to open radially inward; a stator winding having a plurality of winding phase portions installed in the stator core, lead wires of the plurality of winding phase portions being led axially outward within a predetermined circumferential range from an axial end of a first coil end group formed at a first axial end of the stator core; and a first mass adjusting portion disposed at a first end of the stator core, the first mass adjusting portion adjusting a circumferential mass imbalance relative to a central axis of the stator core resulting from a circumferential bias in positions from which the lead wires are led out.
