Abstract
Provided is a stator for rotating electrical machine that can avoid the sagging of teeth stacked at the distal ends under the self-weight. A stator core is a laminate of metal foil members stacked in a direction of a rotation axis of the rotating electrical machine. Each tooth has a pair of side walls facing the neighboring teeth in the circumferential direction. The stator includes a pair of insulating reinforcing members so as to become a bridge between the corresponding tooth and a part of the yoke and sandwich the corresponding tooth from both sides in the direction of the rotation axis while exposing the pair of side walls; insulating fixing members, each fixing member fixing the corresponding pair of reinforcing members to the corresponding tooth while wrapping around the pair of reinforcing members and tooth; and coils formed as distributed windings at the teeth fixed with the fixing members.
