PURPOSE:To improve the follow-up action of magnetic fluxes which passes between interpoles to a load current by providing a portion having no electric shortcircuit due to a padding perpendicularly to the magnetic path which passes between the interpoles at the laminated yoke between the interpoles. CONSTITUTION:An annular thin iron plates 1 are laminated, and a laminated yoke 3 is formed by integrating with a plurality of connecting members 7 having the prescribed interval in a peripheral direction to the outer periphery and extending in a laminating direction and a build-up welding 8. The members 7 of the yoke 3 and the peripheral position of the welding 8 are provided between an interpole 5 and an interpole 5 adjacent to the previous interpole 5, are formed shorter than the length of the laminator of the yoke 3, and are formed in a zigzag shape between the peripheral adjacent interpoles. Further, the adjacent paddings 8 are formed to be superposed in the laminating direction. |
