Abstract: In closed cooling water systems of the kind where deionized and usually deaerated cooling water comes into contact with copper or copper alloys, the formation of scales, depositions due to general copper corrosion is eliminated by the addition of H2 to the cooling water system. The product formed in anoxic (O2-free) water may be described as CuOyHx, but this product can be reduced and, thus, avoided if a sufficient amount of hydrogen is supplied. The life of the stator coil copper pipe for cooling water in an electric generator can be extended significantly by this invention, which is applicable also to other fields, such as closed cooling water systems for particle accelerators and nuclear fusion reactors (such as ITER), for example. In addition, the maintenance cost for such water cooling systems in contact with copper metal will be reduced drastically.

Abstract: A cooling system for a sealed permanent magnet generator is disclosed that has a rotor shaft that is hollow. Permanent magnets mount on the exterior of the hollow rotor shaft. The rotor shaft has a pressed aluminum tube in various configuration on the inside bore with an end-mounted fan. The aluminum tube acts as a heat sink to draw the heat generated by the magnets through the rotor shaft and aluminum tube. The fan draws cooling air through the hollow bore of the rotor shaft thus cooling the magnets and forces the heated air through passages on the exterior of the stator housing. Because the airflow is not in contact with the electrical portions of the generator the cooling system will perform in dusty, wet and explosive environments. In another configuration a refrigeration compressor installed in the rotor shaft bore cools the rotor shaft and the fan cools the stator passages.
