ABSTRACT:
A dynamoelectric machine (e.g., an induction motor) for use in a dishwasher application or the like is disclosed, with the motor having its rotor shaft extending generally vertically, and having an endshield disposed horizontally. The endshield is so structured as to have an upwardly facing trough or the like formed in the upwardly facing surface of the endshield for channeling water which may drip down onto the endshield radially outwardly away from the rotor shaft to portions of the endshield located out beyond the stator core and windings of the motor. Drain openings or tubes are provided in portions of the endshield out beyond the stator core and windings such that the water channeled to the drain openings is prevented from coming into contact with the stator and windings of the motor.
