ABSTRACT:
A gearless air motor utilizes a high speed rotor having turbine buckets defined in epoxy rather than metal to substantially avoid the danger inherent in high speed rotor fragmentation. The unit has a housing which contains the compressed air chamber, the rotor chamber and a speed reduction chamber in which a toothed belt speed reduction system avoids the use of gears for speed reduction, with their relatively high friction and noise output.
