ARMATURE OF ROTATING ELECTRICAL MACHINE AND METHOD FOR MANUFACTURING ARMATURE OF ROTATING ELECTRICAL MACHINE

摘要

In the present invention, core blocks are connected with each other by a mutually engaged first contact surface joint and positioning joint, and a mutually engaged second contact surface joint and swaged joint. The first contact surface joint includes a first contact surface that is in contact with the first end face of the core block having the positioning joint, and a first joint surface which is inclined at a sharp angle with respect to the first contact surface and makes contact with the positioning joint. The second contact surface joint includes a second contact surface that is in contact with the second end face of the core block having the swaged joint, and a second joint surface which makes contact with the swaged joint. The swaged joint is curved by plastic deformation in the direction of pressing the second joint surface. The first contact surface joint is pressed in a direction of fitting between the positioning joint and the first end face by the second joint surface being pressed by the swaged joint.
