PURPOSE:To prevent a shortcircuit trouble between a coil and a core by providing to incline the hole of insulating paper so as not to be linear along the axis of a slot. CONSTITUTION:Insulating paper 3 which is provided to incline to the axis of a slot 2 formed on the outer periphery of a circular core 1 at the hole 3a similar in C shape to the section of the slot is inserted into the slot 2. In the paper 3 are contained wavy wound upper and lower layer coils 4, 5 made of flat armature conductors. Since the hole 3 of the paper 3 is inclined to the X-X line, a wide part 3a1 and a narrow part 3a2 are formed on the side face of the paper 3 at the hole 3a side. In this manner, the shortcircuit trouble between the coils 4, 5 and the core 1 can be prevented. |
