ABSTRACT:
A fluid deflecting baffle is provided for use on an electric motor to be used in an environment where liquid may otherwise pass through a vent opening in an endshield of the motor. The baffle is secureable to the endshield and extends in a partial covering relationship with the vent opening. The baffle includes a vent passage therethrough and has at least one liquid flow obstructing louver that extends across the vent opening to deflect liquid away from the vent passage while allowing venting air to flow through the vent passage. The louver includes a generally flat liquid deflection surface that is disposed at an oblique angle relative to the axis of the motor and at least partially faces a venting direction of incoming air and fluid.
