Abstract
A stator includes star-connected coils of a plurality of phases. Each coil has bodies each configured by connecting conductors in series. Each body is wound while passing alternately through an M-th layer and an (M+1)-th layer of a slot. Each body includes: a first terminal; a first part wave-wound from the first terminal to one side in a circumferential direction; a folded portion connected to the first part on the one side; a second part wave-wound from the folded portion to the other side in the circumferential direction; and a second terminal connected to the second part on the other side. The first parts of the bodies of the same phase are sequentially arranged in slots arranged one by one on the one side. The second parts of the bodies of the same phase are sequentially arranged in slots arranged one by one on the other side.
