Abstract:
A winding method of an armature winding a coil by drawing out a wire from a plurality of nozzles, on an armature core which is provided on a shaft and on which a plurality of core slots extend in an axial direction thereof and is radiately formed, said winding method comprising the steps of:moving each of said nozzles from one end side of said armature core to the other end side, and inserting the wire into a first core slot, under the condition that each wire is pressed to said shaft by a press clamp; moving each of said nozzles from the other end side of said armature back to the one end side, and inserting the wire into a second core slot different from said first core slot, under the condition that each wire is pressed to said shaft by a press clamp; forming a coil end portion by hooking, around a shaping hook, a crossover portion which is formed in both sides of an end surface of said armature core and connects each wire existing in said first and second core slots and by bending the crossover portion by said nozzles; making said nozzles close to said shaft, and thereby pressing said crossover portion on said shaft; and pressing said coil end portion to said shaft by said press clamp.
