Abstract
An electric motor which has an extended service life in high moisture environments. The motor includes non-moisture absorbing (i.e., non-hygroscopic) electrical insulation applied to the magnet wires comprising the stator coils of the motor, non-moisture absorbing ground insulation, a double-cured protective insulation coating applied to the stator coils and to the electrical connections thereof, and a connector insulation cap which effectively seals moisture out of the stator coil electrical connections. A method of manufacturing such moisture resistant motors is also disclosed.
