Abstract
A rotor for a pneumatic tool having electricity-generating capabilities includes a shaft and an integral rotor body. The rotor body includes recesses dimensioned to receive an insulated subassembly having a magnet received within a nonmagnetic insulator to allow flux to be concentrated against stator windings. The rotor can be used in a conventional pneumatic tool, but can also be fitted with the insulated subassemblies in order to cooperate with a stator in the tool to generate electricity upon rotation of the rotor when pressurized fluid is applied to the vanes. A ring stator is connected to a supporting circuit by a connector and is supportable by a nonmagnetic end plate of the pneumatic tool and is disposed between the rotor and the rotor bearing.
Claims14
An end plate for supporting a ring stator for cooperating with a rotor in an integrated electricity generator for a pneumatic tool, wherein said stator comprises:
- an annular ring dimensioned to receive a shaft of said rotor;
- at least one induction pole, each of said at least one induction pole depending from said annular ring and having mounted thereon a respective coil;
- an output connector connected to said coils for transferring generated electricity to a load;
- and
- wherein said end plate is formed of a nonmagnetic material and comprises
- an end wall having an opening dimensioned to receive said shaft of said rotor;
- an annular side wall depending from said end wall and having formed on its inward side a terminal slot for accommodating said connector and cavities for accommodating respective ones of said coils of said stator;
- wherein said stator may supported by said annular side wall against said annular end wall.
A stator for cooperating with a rotor in an integrated electricity generator for a pneumatic tool, comprising:
- an annular substrate having an opening therethrough for accommodating a shaft of said rotor;
- at least one induction pole, each of said at least one induction pole depending from said annular substrate and having mounted thereon a respective coil;
- an output connector connected to each said respective coil;
- wherein said output connector transfers generated electricity from each said respective coil when said rotor rotates relative to said stator.
In an integrated electricity generator for a pneumatic tool, an end plate for supporting a stator, said stator having a ring shape, at least one coil and an output connector for transferring generated electricity from said coil, said end plate formed of nonmagnetic material and comprising:
- an end wall having an opening therethrough for receiving a shaft of a rotor;
- an annular sidewall depending from said end wall and having formed therein a terminal slot for accommodating said connector and at least one cavity for accommodating a respective one of said at least one coil.
