  • Motor drive cover for protection against contaminants
    Patent number: 10447107
    Abstract: A cover for a motor drive is provided. The cover includes an opening (often at the bottom of the cover) to allow air to pass to an air inlet of the motor drive and an opening (often near the top of the cover) to allow air from an air outlet of the motor drive to exit the cover. A hood provides rain protection for the drive and a separator (such as a baffle) within the enclosure prevents air flowing within the enclosure from the air outlet to the air inlet of the drive. The hood and/or the separator are shaped to direct air from the air outlet away from the enclosure in order to substantially reduce the re-circulation of air from the air outlet to the air inlet of the drive.
