Stator assembly of rotary electric device and method of assembling the same

摘要

A stator assembly of a rotary electric device is manufactured and assembled at reduced cost with an enhanced level of precision. A stator assembly of a rotary electric device comprising a yoke (55) provided with a plurality of stationary magnetic poles and a yoke plate (55a) bonded to said yoke by means of synthetic resin in a mold to form an integral unit for enclosing a stator coil is assembled by bringing an alignment pin (7a,7b,4a,4b) arranged on a jig for combining the yoke and the yoke plate into engagement with a corresponding alignment section (55f,55g) of the yoke and the yoke plate to put the yoke and the yoke plate together in order to produce a unitary stator assembly and a step of placing the unitary stator assembly of the yoke and the yoke plate in an injection metal mold (8,9) with said alignment section fitted to an alignment pin (8c,9c) arranged in the mold for mutual engagement and injecting synthetic resin into the mold to bond the yoke and the yoke plate together.
