The present invention relates to a method of insulating a motor, comprising: providing a impregnating resin; heating up the motor windings with electricity to 100-120° C., and potting the motor windings with the impregnating resin for 2-5 min at that temperature; heating up the motor windings with electricity to 140-160° C., and trickling the impregnating resin for 3-8 min for insulation; heating up the motor windings with electricity to 165-175° C., and curing for 15-45 min. The method of insulating a motor provided by the present invention has a higher resin filling level and a higher resin utilization rate, as well as faster curing speed.

Method of insulating a motor

Provided is an ATF (Automatic Transmission Fluid) oil and corona-resistant enameled wire for electric vehicle motors, belonging to the insulating materials field. The ATF oil and corona-resistant enameled wire for electric vehicle motors comprises a copper conductor and an insulating layer, wherein said insulating layer from inside to outside is composed of ATF oil and corona-resistant protective film, corona-resistant PAI film, ATF oil and corona-resistant protective film, corona-resistant PAI film, ATF oil and corona-resistant protective film. The ATF oil and corona resistant enameled wire of this disclosure is suitable for the preparation of oil-cooled electric vehicle motor loose winding coil due to the advantages of good manufacturability, excellent ATF oil and corona resistance, and low manufacturing cost.

ATF oil and corona-resistant enameled wire for electric vehicle motor and preparation method thereof

A corona-resistant enameled round wire and preparation method of making such which is suitable for electric vehicle motors and has a copper conductor and an insulating layer. The insulating layer clads the copper conductor and has in sequence from inside to outside, a corona- resistant polyamideimide coating, a corona-resistant special resin coating, a corona-resistant polyimide coating, a corona-resistant modified silicone resin coating, and a corona-resistant polyamideimide coating.
