The 125 and 2 50-horse- 1power machines have, asshown in Fig. i, four polepieces, and in the 500-horse-power size, seeFig. 2, there are sixpoles. In this latter ma-chine, the shaft has a bearing outside of the pulle\-, which relievos it in a largedegree from the bending strain, and adds much to therigiditv of the armature.
