Divided core of rotary electric machine, rotary electric machine, manufacturing method of divided core of rotary electric machine, and method of manufacturing rotary electric machine

摘要

Problem to be solved: to provide a split core and a rotary electric machine of a rotating electric machine which suppresses eddy current loss without using an adhesive.First core sheet 6 isThe first groove 10 formed in the outer x X1 of the radial X of the yoke partHaving projections 9The projection 9 isThe length Z of the first direction 13 of the first portion 13 formed in the first groove part 10 of the yoke partThe first groove 10 is formed to be smaller than the length W1 in the circumferential direction Z;AndThe length W3 in the circumferential direction Z of the second portion 12 formed in the outside X1 of the radial direction X from the yoke partThe length of the first groove 10 is equal to or equal to the length Z of the circumferential direction Z of the first groove partThe second core sheetThe second groove 8 is formed in the outer X axis X of the yoke xThe projections 9 of the first core sheet 6 are bent toward the second core sheet 7 and fitted into the second groove 8 of the second core sheet 7.Diagram
