ABSTRACT:
An electric motor comprises a stator, a rotor, and an interface plate. The interface plate is fixed to the stator and is configured to couple the electric motor to a pump. The interface plate comprises a shaft opening, a cavity, a ventilation passageway, a fluid discharge portion, a drainage passageway, and an upwardly extending surface. The rotor shaft extends horizontally through the shaft opening. The cavity is in communication with the shaft opening. The ventilation passageway extends upward from the cavity and is in communication with the cavity and with the ambient air. The drainage passageway is in communication with and extends downward from the cavity. The drainage passageway is configured to channel liquid downward from the cavity and to the fluid discharge portion. The upwardly extending surface is positioned where the upwardly extending surface will inhibit liquid from migrating from the fluid discharge portion to the stator.
