PROBLEM TO BE SOLVED: To solve the problem of a rotary electric machine in which a coil end winding and a support ring are fastened and fixed by being totally manually bound with a binding material, so that many times and costs are required, and there is a large rotary electric machine having 500 fastening portions or more of the coil end winding and the support ring, in which reduction in the total number of fastening portions with binding materials is required while fastening rigidity of the coil end winding of a stator is maintained.SOLUTION: In a rotary electric machine, when a coil end winding and a support ring, or coil end windings adjacent to each other, are bound with binding materials, an intermediate plate with a predetermined thickness is arranged between the coil end winding and the binding materials so that the binding materials are wound over the plate to bound them. Accordingly, a distance between the binding materials is increased by the intermediate plate, so that fastening rigidity of fastening portions can be increased. The increased rigidity can be calculated in a design step of the rotary electric machine in advance, so that the total number of fastening portions with the binding materials can be reduced while fastening rigidity of the coil end winding is maintained. |
