Abstract
A stator coil includes a belt-shaped winding band and a same-layer bridging portion. The winding band makes one or more rounds, while turning back in the axial direction a plurality of conductor wires which are aligned in parallel at a pitch of electric angle π (pi). The same-layer bridging portion connects a pair of the conductor wires which are of the same phase at the end portion of the winding and which are arranged in the same layer of the slot. Such arrangement enables forming a compact multi-phase stator coil.
