Abstract
According to one embodiment, a stator includes a stator core and a stator coil. The stator core includes an annular yoke, and a plurality of teeth each extending from an inner periphery of the yoke in a radial direction and arranged in a circumferential direction of the yoke at intervals, in which a gap between a pair of teeth adjacent to each other in the circumferential direction forms a slot extending in the radial direction. With respect to the pair of teeth and the slot, only one of the teeth includes a convex holder-shaped part which projects in the slot toward the other tooth and extends in an axial direction. The stator coil includes a plurality of linear conductors aligned in the radial direction in the slot and held in the slot by the holder-shaped part.
