ABSTRACT:
A motor having a fluid bearing in which a clearance control unit is provided in a housing so as to stably rotate a rotor shaft of a rotor by controlling a clearance between the rotor shaft and a shaft groove. The clearance control unit includes a clearance control rod inserted into a through hole which passes through the shaft groove from an external side of the housing, and a feed gear for feeding the clearance control rod. One end of the feed gear is rotatably mounted into one end of a groove formed to be connected with the through hole, and the other end of the feed gear is formed to fit a feed screw exposed to the external side of the housing into a screw hole. The feed gear moves the clearance control rod closer to the rotor shaft, causing an increased air pressure between the clearance control rod and the rotor shaft for moving the rotor shaft into center alignment in the shaft groove.
