  • Method of forming an integral water-cooled circuit ring bus bar assembly for high frequency generators
    Patent number: 5103552
    Abstract: An improved circuit ring and method of assembly for use in electrical machines, such as power generators, motors and the like, including an integral bus bar for conducting current to a machine terminal. The circuit ring is fabricated from hollow copper tubing of a rectangular cross-section and of a size which will allow electrical circuit leads to be brazed thereto in such a manner as to avoid damage to insulation. Cooling fluid is passed through the tubing so that the rings can be assembled and used in high power density electrical machinery.
