Abstract
A stator includes an annular stator core that is comprised of a plurality of stator core segments, an outer ring that is fitted on the radially outer surfaces of the stator core segments so as to fasten them together, and a stator coil mounted on the stator core. Each of the stator core segments is formed of a plurality of stator core sheets that are laminated in the axial direction of the stator core. Each of the stator core sheets has a reinforcement portion that includes a recess formed in one of the major surfaces of the stator core sheet and a protrusion formed on the other major surface. The stator core sheets are laminated so that for each adjoining pair of the stator core sheets, the protrusion of one of the stator core sheets is fitted in the recess of the other stator core sheet.
