Abstract: An air-cooled weather-protected motor (10) configured for vertical-shaft applications, such as mounting above an outdoor, vertical-shafted pump (P) for pumping fluid (e.g., water, oil, etc.) through a pipeline (L), is disclosed. The illustrated motor (10) broadly includes a stator (12), a shafted rotor assembly (14) rotatably supported relative to the stator (12), and a vented protective motor enclosure (16) enclosing the stator (12) and the rotor assembly (14). The enclosure (16) includes a primary motor housing (18) and a pair of filtration boxes (20) and (22) removably coupled to either side of the housing (18) to guard air intake through the housing (18) to the stator (12) and the rotor assembly (14). The improved motor enclosure (16) provides an inventive coupling mechanism that enables the modular filtration housings (20,22) to be quickly and easily secured to the primary motor housing (18) to protect the air intake openings (68,70) from weather and other undesired debris.
