In one aspect, a device comprises a means for generating an aerostatic force exclusive of a buoyancy force acting on the device, wherein the aerostatic force acting on the device is a significant portion of a total force acting on the device due to the aerostatic force exclusive of a buoyancy force, a reaction force, and a buoyancy force. In another aspect, a device includes a cavity with a first internal pressure of a first fluid, and a plurality of conduits extending from the cavity to an environment outside of the device with a second pressure different from the first pressure, wherein fluid flows through the plurality of conduits, and an aerostatic force exclusive of a buoyancy force acting on the device is greater than a reaction force acting on the device due to the fluid flow or is a substantial portion of the total force acting on the device.

Fluid-operated dynamoelectric converters for medical or dental devices are described. The dynamoelectric converters have: a fluid line which is designed in one piece with an outer sleeve of the dynamoelectric converter and protrudes at its end which faces away from the dynamoelectric converter beyond a connecting end of the medical or dental device; a fluid-operated impeller which is designed in one piece with a rotor sleeve receiving the magnetic element; a one-piece, sleeve-shaped magnetic return element which surrounds the rotor and the electric winding of the stator and has a magnetically conductive material.
