Stator for a rotating electrical machine and method of manufacturing the stator

摘要

A stator for a rotary machine includes a rotor 7 and a stator 8 having a stator iron core 15 disposed oppositely around the outer circumference of the rotor 7 and a stator coil 16 fitted around the iron core 15, wherein the iron core 15 has a laminated iron core 150 with plural axially extending slots 15a formed circumferentially at predetermined pitches, an insulating resin 100 is coated on an axial end face 15f of the iron core 15 and an inner wall face of a slot 15a in the laminated iron core 150 to provide insulation between the iron core 15 and the stator coil 16, and the iron core is cylindrically shaped by bringing both circumferential end portions 15g of the laminated iron core 150 into contact to bend the laminated iron core 150 so that an opening face 15b of the slot 15a is directed inside.
