The multi-pole motor features numerous slots, short span and high copper space factor. For such motors, adopting the common copper wire insertion technology for three-phase asynchronous motors will make it difficult to operate and increase failure rate of stator core winding. To deal with this problem, an improvement scheme of 15 kW generator′s winding stator technology is introduced, by which the winding inserting will become easier with the failure rate lowered and working efficiency improved.
