Hvac motor and cover structure

摘要

An HVAC motor assembly for mounting to a housing includes a motor having a generally cylindrical portion and a connector extending from the cylindrical portion. The motor also has air flow passages therethrough. The assembly includes a one-piece cover structure including a generally cylindrical section having an opening at one end thereof and a closed end opposite the one end, and an interior between the ends. The motor is disposed in the interior so that one end of the motor is covered by the closed end. A flange structure extends from the cylindrical section. A first passage in the cover structure is in open communication with atmosphere and in communication with the interior. The first passage communicates with a connector opening in the cover structure. The first passage is sized to permit the connector of the motor to pass therethrough and the connector opening receives the connector. The connector opening is sized to fit tightly with the connector to substantially prevent air from passing between the connector and the cover structure. A second passage of the cover structure is in open communication with the interior and is in communication with the air flow passages of the motor so that air may enter the second passage and exit through the air flow passages to cool the motor. A vibration damping member is provided between the cylindrical portion of the motor and the cylindrical section of the cover structure to dampen vibration of the motor.
