METHOD OF MANUFACTURING LAMINATED CORE

PROBLEM TO BE SOLVED: To provide a method of manufacturing a laminated core which can blank both a stator piece and a rotor piece from a steel strip, can eliminate the deviation of a plate thickness, and can form a skew. SOLUTION: The laminated core 1 is composed by caulking and laminating a prescribed number of core pieces 1t, ..., and includes ring-shaped yokes 2, ..., and a prescribed number of teeth 3, ... which protrude inward the yoke 2, ... The laminated core also includes a prescribed number of bendable connecting parts r, ... which connect cutting parts c for developing the ring-shaped yokes 2, ... into arbitrary shapes and the yokes 2, 2 toward which the teeth 3 protrude and to which the teeth adjoin, and develop the yokes 2, 2, ... which are divided by the cutting parts c when winding coils to the teeth 3 into arbitrary shapes.
