A stator core is formed by deforming a core assembly having core pieces coupled in a strip form into an annular shape, and by joining both ends of the core assembly together to make a core-fastening portion. Individual phase windings are routed from one end of the core assembly toward another end. Lead portion () of phase winding () and lead portion () of phase winding () make up respective wire terminals. Lead portion () of another phase winding () is extended through a plural number of the core pieces in a direction of the lead portions (and), and a wire terminal of the extended lead portion () and the wire terminals of the other lead portions (and) are electrically connected to provide a neutral point of three-phase Y-connection circuit.
