1. be used to make the method for the stator or the rotor of the motor that comprises distributed waveform winding, each winding wire (15) of this waveform winding is configured as continuously the linkage section (20) and the winding overhang (22) that respectively two adjacent linkage sections (20) of a winding wire (15) is linked to each other in the groove that inserts stator or rotor in wave shapely, described winding overhang protrudes in the end face of stator or rotor, wherein, per two in pairs configurations, the winding overhang (22) that is in the winding wire (15) in the same groove with adjacent linkage section (20) protrudes in the end face of stator or rotor in the end opposite of groove;

  • It is characterized in that, in order to form two line thighs of at first itself entwining and entwining mutually then (10,12), respectively-to reel and produce a plurality of pitch of the laps circles simultaneously in the template of bar shaped with interval from the parallel winding wire (15) of cable guiding device supply by making the n root, described template can be rotated around its longitudinal axis, wherein,-for the stator or the rotor of the groove that will take with the waveform winding with the number that can be divided exactly by 2n, alternately in a job step A, on template, produce a linkage section (20) and one respectively and constitute dual end sections by bending with predetermined space corresponding to the spacing of stator or rotor recesses by each root of parallel winding wire (15), this end sections has the winding wire length of winding overhang (22), and-in a job step B, will be in job step A formed each linkage section (20) at first end that keeps under its constant at interval situation together with the adjacency of the end sections under respectively, with second end of cable guiding device together with this end sections, relative to each other, axial rotation mobile n predetermined space doubly on a direction of being scheduled to along template, form each winding overhang (22) thus-after job step A and many repetitions of B, on template, produce each linkage section (20) that is used for a last n stator or rotor recesses again,-and then, two independent prefabricated line thighs of entwining (10,12) itself are reeled with a kind of axial relative position stackedly, in described axial relative position, it is superimposed that each linkage section (20) that is produced on the opposite sides of bar template by corresponding parallel winding wire (15) respectively is in, and and then transversely be inserted in stator or the rotor recesses in the direction of the longitudinal extension of stator or rotor recesses as a waveform winding (14) that totally connects together under the state against each other.
