Patent ID: 8049385

Claim:
An electric motor comprising: a rotor rotatable about a horizontal axis; a stator spaced radially from the rotor; a case defining an internal motor chamber in which the stator and rotor are housed, with the case presenting axial margins, said case including an endshield adjacent one of said axial margins, said endshield defining a vent opening therethrough so that vent air is permitted to flow in a generally axial venting direction from outside the motor chamber to inside the motor chamber, said vent opening being disposed below the axis; a fluid deflecting baffle operably secured to the endshield in a partial covering relationship with the vent opening, said baffle defining a vent passage therethrough to permit air to communicate with the vent opening in the endshield, said vent passage being disposed below the axis, said baffle including at least one liquid flow obstructing louver extending across the vent passage to deflect liquid flowing at least partially in the venting direction away from the vent passage, said louver including a generally flat liquid deflection surface, said deflection surface being disposed at an oblique angle relative to the axis and at least partially facing the venting direction, said endshield presenting internal and external sides; and an endshield cover operably secured to the external side of the endshield, said cover including a body projecting axially from the endshield and extending generally radially coextensively with the area of the endshield disposed above the axis, such that the body presents an overhanging portion below which the vent opening is located.
