PURPOSE:To enhance the reliability with small size by flattening the linear coil portions of an armature winding in a tangential direction, contacting it with the inner periphery of a stator core, and disposing it on the outside of an inside coil supporting member. CONSTITUTION:The coil of an armature winding 4 is formed in a hexagonal shape, its linear coil portions are flattened tangentially inside an annular stator core 1, and disposed in two layers. An inside coil supporting member 3 is formed in an annular inner peripheral shape of outer polygonal shape. The linear portions are disposed on the outsides of the polygonal shape, and the outsides of the linear portions are secured through a outside coil supporting member 7 by an elastic key 8 to the core 1. Thus, the linear portions becomes the same polygonal shape as the outer periphery of the member 3 to stabilize the coil and to rigidly support it. The outsides are fixedly secured to the inner periphery of the core 1 effectively by the key 8 through the member 7. |
