Abstract

See full text

A water-resistant electric motor having an end bell with a passage that prevents the formation of a vacuum between the shaft seal and the shaft bearing. The passage extends from the interior region of the motor through the end bell bypassing the bearing to communicate with a gap between the seal and the bearing. The motor housing includes a vent to expose the motor's interior region and the gap to atmospheric pressure or to a source of higher-pressure air or gas to prevent water from being sucked into the motor's interior.
