A rotary atomizer comprises an electric motor having a stator and a rotor, a vertical shaft, one or more porous gas bearings configured to provide frictionless radial and axial support to the shaft, and a rotating disc installed at a lower end of the shaft, said rotating disc configured to spray liquid into the form of fine particles. A gap detection system monitors a distance between the porous gas bearings and the vertical shaft. Bushings on the motor housing help to maintain precise alignment of the rotor during installation and maintenance.

A rotary nozzle having a rotating shaft operating within a cylindrical housing is balanced by allowing passage of a small amount of pressurized fluid to be bled to an area between the outside of the opposite end of the shaft and the inside of the housing where the fluid force acts axially in an opposing direction upon the shaft to balance the axial inlet force exerted by the pressurized fluid. The balance of axial forces is self-regulating by controlling escape of the fluid through a tapered or frusto-conical region between the shaft and housing. A plurality of centrifugal weight segments around the inlet end of the shaft are thrust outwardly against the cylindrical housing to retard rotational speed while pressurized fluid around the centrifugal weight segments provides a fluid bearing between the weights and the housing.
