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

Abstract: A stator assembly of a rotary electric device is manufactured and assembledat reduced cost with an enhanced level of precision. A stator assembly ofa rotary electric device comprising a yoke provided with a plurality ofstationary magnetic poles and a yoke plate bonded to said yoke by means ofsynthetic resin in a mold to form an integral unit for enclosing a statorcoil is assembled by bringing an alignment pin arranged on a jig forcombining the yoke and the yoke plate into engagement with a correspondingalignment sections of the yoke and the yoke plate to put the yoke and theyoke plate together in order to produce a unitary stator assembly and astep of placing the unitary stator assembly of the yoke and the yoke platein an injection metal mold with said alignment section fitted to analignment pin arranged in the mold for mutual engagement and injectingsynthetic resin into the mold to bond the yoke and the yoke platetogether.
