METHOD FOR INSERTING THREE-PHASE COIL INTO STATOR CORE, AND DEVICE FOR INSERTING THREE-PHASE COIL INTO STATOR CORE

摘要

PROBLEM TO BE SOLVED: To provide a method for inserting a three-phase coil into a stator core so that a three-phase coil group can be inserted into each slot by the single push-up operation of a stripper without damaging the three-phase coil group, and a device for inserting the three-phase coil into the stator core.;SOLUTION: A three-phase coil group is hooked to a plurality of blades 17, coil groups U1 and U2 are arranged on a first stripper 30, coil groups V1 and V2 are arranged on a second stripper 50 in a state of straddling on the rib 43 of a cross member 40, coil groups W1 and W2 are arranged on the second stripper 50 in a state of not-straddling on the rib 43 of the cross member 40, the coil groups U1 and U2 are inserted into respective slots 5 by the first stripper 30, the coil groups V1 and V2 are then inserted into the respective slots 5 by the second stripper 50 while being pushed up by the cross member 40 preceding to the coil groups W1 and W2, and thereafter the coil groups W1 and W2 are inserted into the respective slots 5 by the second stripper 50.;COPYRIGHT: (C)2009,JPO&INPIT
