Abstract: A motor assembly comprises a first end frame, a second end frame including at least one air outlet aperture, an air shroud surrounding a stator between the first end frame and the second end frame, the air shroud cooperating with the stator to form at least one air passage, and cooperating with the first end frame to form at least one air inlet aperture. The motor assembly also comprises a fan mounted on the rotating shaft, the fan operable to generate an air flow of ambient air through the at least one air inlet aperture, the at least one air passage and the at least one air outlet aperture.
