More Information
Summary:A ventilation fan (10, 200, 400) includes a shaft, a rotor (84, 364, 466), a motor housing (26, 216, 416), a bearing housing (28, 218, 418), and an air bearing. The shaft has a shaft body that extends between a first shaft end and a second shaft end. The shaft body defines a first port (90) and a bore (92). The rotor (24, 214, 414) is disposed about the shaft. The motor housing (26, 216, 416) is disposed about the shaft and is axially spaced apart from the rotor. The bearing housing (28, 218, 418) is disposed about the shaft. The air bearing (330, 520) is disposed proximate the second shaft end and is disposed between the bearing arm and the second shaft end.
