Quality brazing for turbine generators

24th Aug 2017

Electric generators convert kinetic energy into electrical energy and are part of every wind tower. Generators of various designs are used, such as asynchronous and synchronous types with permanent magnet or induction generators. Copper and steel are the main base materials used for the generators, with copper used primarily for its electrical conductivity. Aluminium is also becoming more important. Electrical generators consist of a static part (the stator) and a rotating part (the rotor). Brazing is applied in generators with a short-circuit ring rotor (end ring). The brazed joint is located between the end ring and the ends of the rotor bars; and the ring and bars are made of solid copper. With stators, brazing is often used to connect the pole coils on both sides of the stator.
