PURPOSE:To increase the reliability of insulation at a displacement section and to efficiently perform winding work by a method wherein the displacement section of a field coil wound in multirow and multistep is locally concentrated and the displacement section is arranged at one coil end to eliminate displacement work at the time of winding assembly. CONSTITUTION:A displacement section 25 is locally concentrated on one end section 24 of a coil 3. The field coil 3 after completing winding at the displacement section 25 is enlarged by 1-1.5 turns in the upper and lower directions. However, the application of unnatural power to the displacement section 25 at the time of work or operation can be avoided by slightly thinning ground insulation 7 at the lower part or that at the upper part. The displacement section 25 may just fixed to the coil end section 24 at the beginning of winding assembly and the short-circuit accident at the displacement section 25 can perfectly be prevented. |
