摘要： PROBLEM TO BE SOLVED: To provide the manufacturing method of an armature by which the armature can be manufactured automatically. SOLUTION: A coil 10 made from one wire is wound on upper and lower separated winding frames 20A and 20B so as to have annular shapes in winding directions opposite to each other, and two coil members 30A and 30B are formed. The two coils are deformed in radial directions to form two deformed coils 40A and 40B with unevennesses. Further, after the deformed coils 40A and 40B are formed, one of the upper and lower separated winding frames 20A and 20B is turned relatively to the other, and the deformed coils 40A and 40B are put on the other so as to have their respective recessed parts and protruding parts face each other to form a stator coil 50. The stator coil 50 is inserted into a plurality of slots of a stator core 70 to manufacture an armature.
