Abstract
In a method for producing a stator of an alternating current dynamo-electric machine, a laminated assembly with a roughly rectangular parallelopiped shape is produced, and a stator coil assembly is disposed in slots of the laminated assembly. Thereafter, a cylindrical stator core is produced by bending the laminated assembly. The stator coil assembly can thereby be easily disposed in the slots at a higher density, and damage to the conductors of the stator coil assembly can be prevented.

A method for producing a stator of an alternating current dynamo-electric machine, comprising the steps of:
- (a) laminating a plurality of magnetic strips together to produce a laminated core assembly with a rectangular parallelopiped shape having a plurality of slots;
- (b) disposing a stator coil assembly in said slots;
- and
- (c) bending said laminated core assembly together with said stator coil assembly to produce a cylindrical stator.
A method for producing a stator of an alternating current dynamo-electric machine, comprising the steps of:
- (a) laminating a plurality of magnetic strips together to produce a laminated core assembly having a rectangular parallelopiped shape and having a plurality of slots;
- (b) disposing generally flat shaped electrical windings in said slots;
- and
- (c) bending said laminated core assembly to form at least an arc of a cylindrical stator, wherein said laminated core assembly is bent after said electrical windings are disposed in said slots.
