TOTALLY ENCLOSED FAN COOLED MOTOR

摘要

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. The motor assembly further comprises a housing coupled to the air shroud and defining an inner space containing an electronic module operable to control the motor assembly, the housing including a cap operable to permanently seal the inner space. Finally there is provided a thermostat in thermal relationship with the at least one portion of the set of windings.
