Abstract
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 15 a formed circumferentially at predetermined pitches, an insulating resin 100 is coated on an axial end face 15 f of the iron core 15 and an inner wall face of a slot 15 a 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 15 g of the laminated iron core 150 into contact to bend the laminated iron core 150 so that an opening face 15 b of the slot 15 a is directed inside
