STATOR OF DYNAMO-ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To eliminate the welding between the circular arc parts of split iron cores disposed in an annular form to hold the split iron cores in an annular form by providing an annular body engaging with the split iron cores to hold the split iron cores in an annular form. SOLUTION: Split iron cores 7 in which iron cores split for every pole unit are connected in a circumferential direction and disposed are provided, and a support iron core 13 having smaller circular arc diameter than the circular arc diameter of the outside circular arc part of the split iron cores 7 is interposed between the laminated steel plates of the split iron cores 7 to form the groove 8 of the circumferential direction in the outer circumference of the split iron cores 7 and to fit an annular body 18 into the groove 8. The annular body 18 is, for instance, a C-shaped annular ring having elasticity and is fitted to the outer circumference of the support iron core 13 to fix the support iron core 13 in an annular form. Also, in the outside circular arc part 9, the inside circular arc part 10 or the coupling winding core part 11 of the split iron cores 7, for instance, V-shaped projection 12 is provided, and by the V-shaped projection 12, it is fitted to the inner surface of the V-shaped projection of the other thin steel plate to fix the steel plates to each other.
