DRYING BY INTERNAL HEAT.- Passing current through windings is one of the most effective means of drying motors. If the measured insulation resistance is in the questionable zone of figure 1, the motor can usually be dried by running unloaded with half-rate voltage applied.
What do you do if your electric motor gets wet?
Motor windings should be removed from their housings, or the cases opened as much as possible.
