Method for manufacturing stator

摘要

A method of manufacturing a stator wherein a stator core is fixed by a centering jig, and in this state, a fixing hole is formed in a flange portion provided on a fastening ring for the stator core, using a central position as a reference for position, by drilling with a drill. The fixing hole is opened to be located at a distance relative to the central position. In a plan view, the fixing hole is opened at a predetermined central angle interval (for example, intervals of 120°) relative to the central position.

1. A method for manufacturing a stator having an annular form and for use in a rotating electric machine, comprising the steps of:
positioning and fixing a stator core on a jig such that a central position of said stator core agrees with a rotational axis of a rotating electric machine,
wherein said step of positioning and fixing said stator core on the jig includes a step of positioning and fixing said stator core on a centering jig such that said central position of said stator core agrees with a rotational axis of a rotatin electric machine; forming a fixing hole in a flange portion provided on a fastening ring for said stator core, using said central position as a reference for positioning, with said stator core fixed by said jig; and fixing said fastening ring to said stator core by shrinkage fitting,
wherein said step of fixing said fastening ring includes fixing said fastening ring onto an outer circumferential surface of said stator core, with said stator core fixed by said centering jig.
