ABSTRACT:
The present invention relates to a motor for an air-tool. More particularly, the present invention is directed to an air driven motor in which the rotor has a plurality of recesses formed between each pair of adjacent vane holding slots. A separator fine is fixed in each recess. Each vane of the rotor is radially displaceable and outwardly biased to expose a compressed air contact surface area. The separator fins add additional compressed air contact surface areas.
