ABSTRACT:
An enclosure is disclosed for use with motors in an outdoor environment. The enclosure serves to prevent moisture and dirt from contacting the motor housing or fan, thereby to prevent condensation inside the motor housing. The enclosure comprises a cylindrical moisture shield disposed about the motor housing to which is attached a rain canopy at one end thereof. An appropriate spacing is provided between the rain canopy and the moisture shield to permit air to be drawn inside of the enclosure to permit air cooling of the motor during operation.
