。C1 Problems, Means, and Effects to be Solved by the Invention In view of the problems of the conventional example, this invention has been developed to solve the problems, means, and effects of the invention in view of the problems of the conventional example. The aim is to improve workability by alternately changing the length of the salient poles of the stator.

は従来例のものと同一である。d. Embodiment The present invention will be described in detail with reference to the accompanying drawings. In FIGS. 1, 2, and 3, the provision of salient poles on the stator 1 is the same as in the conventional example.
然してとの突極に励磁用コイルが巻回される枠４を嵌挿
固定する。然して固定子に設けた突極２と３はそれぞれ
長さを異にする。Then, the frame 4 around which the excitation coil is wound is fitted and fixed around the salient poles. However, the salient poles 2 and 3 provided on the stator have different lengths.

する突極の長き寸法と交互に同一に形成する。As shown in FIG. 2, the length dimension of adjacent salient poles 2 and 3 is tI + 1 from the tip 6 to the root 8, respectively.
'2 + '1 + 72 alternately and identically formed, t
In other words, the dimension of the salient pole 2 is made shorter than the dimension t2 of all the salient poles 3. In FIG. 1, a coil frame 4 around which an excitation coil is wound is inserted up to the roots 8 of the salient poles 2 and 3 of the stator, and the coil frame 4 is formed to have the same length as the adjacent salient poles alternately.
本発明は上記した構成を有するので作業性にすぐれ能率
増進に役立つ等の効果を有する。Since the present invention has the above-mentioned configuration, it has effects such as excellent workability and helping to improve efficiency.
