Research on the Resistance of Key Insulation Materials of New Energy Vehicle Drive Motor to Automatic Transmission Fluid
Oil-cooled new energy vehicle drive motor adopts automatic transmission oil for motor cooling.In order to study the resistance of common insulation materials of new energy vehicle drive motor to automatic transmission fluid,the resistance tests of impregnated paint,enameled wire,slot insulation and insulating sleeve to two types of automatic transmission fluid were carried out,and the properties of insulating materials before and after the tests were studied.The results show that epoxy modified unsaturated polyester materials and polyphenylene sulfide-polyarylamide fiber paper composites has good resistance to automatic transmission fluid.Under the same test conditions,there are obvious differences in the resistance of the same insulation material to different types of automatic transmission fluids.When the oil model changes,oil resistance evaluation should be carried out for key insulation materials.
