Abstract

A wire is wound in a plurality of core slots 15 on an armature core, and thereby a plurality of coils 18 is formed. In the case.where each coil end portion of the coils is formed in a predetermined shape by a shaping-winding method, a coil end portion of a coil wound in each core slot is formed to be close to an end surface of the armature core 12 as it is directed outside of a radius direction of the shaft 11. In the case where coil end portions are formed by a shaping-winding and direct-winding methods, some of coil end portions are formed between the first winding to the predetermined number-th winding coils by a shaping winding method, and the remaining coil end portions are formed between the predetermined number-th winding and the last winding coils by a direct-winding method.
