Abstract
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.
