A pneumatic tool includes a nonmagnetic tool housing; a cylindrical rotor inside the tool housing and rotatable in response to a flow of pressurized fluid through the tool housing; magnets mounted in the rotor; and a stator external to the tool housing. The stator is dimensioned to cooperate with the magnets to, upon rotation of the rotor, generate electrical current for supply to a load.
