Abstract
According to one embodiment, a stator includes a stator core and coils having a rectangular cross-section. In one or more slots, a first rectangular conductor, which is positioned innermost in a radial direction and in which a pair of short sides in a cross section face in the radial direction, and a second rectangular conductor, which is positioned outer side of the radial direction than is the first rectangular conductor and in which a pair of long sides in the cross-section face in the radial direction, are disposed. The first rectangular conductor includes a bending part bent toward a circumferential direction. The second rectangular conductor includes a bending part bent toward the circumferential direction and a twisted part twisted about the circumferential direction.
