PURPOSE:To reduce the size of a rotary electric machine by rigidly integrating a binding string and a coil end insulating layer with thermosetting resin. CONSTITUTION:The coil ends 1a, 1b, 1c of a plurality of coils which are inserted into the stator coil slots of a rotary electric machine are sequentially continuously wound in a loop shape by a binding string 5 substantially in a direction perpendicular to the longitudinal direction of the coil ends. When fully impregnating the coil, the string 5 is impregnated together with the coil with the same thermosetting resin as that used for the coil, the string 5 is heated together with the coil, and the impregnating resin is hardened. In this manner, the size of the machine can be reduced, and sufficiently supporting and fixing functions can be performed. |
