Abstract:
A method of manufacturing a laminated stator core and a laminated stator core manufactured by the method, the method capable of forming a recess 21 over one or both of (a) a lateral portion of an ear piece C of the stator core sheet A to be formed adjacent to the stator core sheet B and (b) a peripheral portion of the annular yoke piece D continuing to the lateral portion, the peripheral portion beside the ear piece C; fitting one ear piece E of the stator core sheet B with a gap in the recess 21; and thereby improving a material yield when the stator core sheets 13 are formed from the strip material 14.
