ABSTRACT:
A tool driven by air or some other non-conductive pressurized fluid, which tool incorporates a generator for powering a lamp and providing a good source of light in the work area. Batteries and a charging circuit may also be supplied for storing excess electricity from the generator so that the lamp can be used even when the tool is not running. In all embodiments disclosed herein, the air cylinder of the motor of the air tool is redone to accept a coil which is electrically connected to the lamp, while permanent magnets turn with the rotor of the air motor. In one embodiment the permanent magnets are embedded in the rotor itself. In another embodiment the vanes of the rotor are manufactured from a permanently magnetic material, and constitute the magnets. In a third embodiment highly magnetic bits, such as rare earth cobalt, are embedded in concentrated areas in the vanes, and these bits create a sufficient magnetic field to cause current to flow in the coil when the rotor is turning. In a fourth embodiment a polarized ceramic rotor magnet is attached to the rotor to cause a current in the coil while the rotor turns. In a fifth embodiment a single pole arrangement is employed. That is, several small coils are embedded in one of the bearing end plates, while a magnet rotor, attached to the rotor of the air motor, carries magnets in facing relationship to the coils. In all embodiments, as the magnets move with respect to the coils, current is generated in the coils, which current is used as described above.
