摘要： The invention relates to a joint between a copper short-circuiting ring (1) and a copper bar (2) of the damper winding in a permanent magnet synchronous machine, wherein the end of the bar is jointed to a hole (9) disposed in the short-circuiting ring by welding them together at the mating surfaces. Further, the invention relates to a corresponding method. According to the invention the short-circuiting ring (1) includes a blocking structure for limiting the heat flux from being conducted further into the short-circuiting ring from the weld between the short-circuiting ring and the bar.
