摘要： PROBLEM TO BE SOLVED: To reduce tensile force and a bending force in the case of pulling of a beltlike member in the stator core of a motor in which the beltlike member is annularly pulled, molded and laminated.
SOLUTION: The stator core of the motor is constituted by pulling the yoke 16 of the beltlike member 12 having a yoke part 16 and comb teeth 18, molding in an annular stator annular member, and laminating the stator annular member. The yoke part 16 of the beltlike member 12 is molded in a waveform shape where the amount of displacement from the inside toward the outside of the yoke part 16 is large, before being molded annularly. In this waveform shape, the elongation of the yoke part 16 when the beltlike member 12 is molded in the annular stator annular member, is given in the waveform shape beforehand. Thus, the tensile force and the bending force when the yoke part 16 is pulled and molded annularly in the annular stable member can be reduced.
