Abstract
The water powered motor includes a casing housing a rotor shaft. First and second water bearings of conical shape support opposite end portions of the shaft for high speed rotation. The central portion of the shaft has turbine wheels subject to high velocity water flow through the casing. The same high water pressure for driving the turbine also provides water to the water bearings to 'float' the rotor shaft so that very high speeds can be attained with minimum friction. The preferred application for the motor is that of a high speed drill for drilling printed circuit boards. However, it may be miniaturized for use as a dentist's drill.
