The housing assembly includes a terminal box positioned at the first end, an end plate coupled to the terminal box and including a plurality of inlet apertures, and a casing coupled to the end plate and extending toward the second end. The stator is fixedly secured to the housing assembly and positioned within the casing. The rotor is rotatably secured to the housing assembly and positioned within the casing such that the stator and the rotor are separated within the casing by an air gap. The fan is positioned inside the casing and is configured to draw air into the housing assembly through the plurality of inlet apertures.
