On core.Since enameled wire and iron core are all metallic conductors, there are the coat of paint flow direction motor iron cores of current of electric breakdown enameled wire
May, so that motor housing be caused to charge, lead to the generation of safety accident.Therefore upper nylon material must be covered on iron core surface
Further around painting envelope curve after skeleton, the absolute insulation between iron core and enameled wire is realized.
It is in assembling, stator skeleton is staggered relatively two-by-two, iron core is placed among skeleton, both hands make power by skeleton and iron
Core closes up fastening.The presence of iron core surface bulge button point is had ignored in the design process of usual skeleton.Therefore on skeleton and iron core
It can not be bonded completely between lower surface due to the presence of protrusion button point.Therefore the skeleton after fastening iron core usually becomes all in slight
In shape, it cannot achieve skeleton inner surface and be close to completely with iron core.Mistake of the skeleton not being close to iron core in postorder coiling enameled wire
There to be greater probability to be suspended on the enameled wire of coiling at full speed in journey, forms bad product.
