METHOD OF SECURING A TUBULAR COMPONENT IN A SLOT OF ELECTRIC MACHINE STATOR

摘要

The coolant tubes (24) are made of polymer material and mounted in a space (23) of corresponding shape to the tube. After insertion in the stator slots they are filled with a pressure medium. The medium is then heated and pressurized so that the tubes soften and expand to adopt the shape of the available space (23). The hot pressure medium is then replaced with a cold medium which causes the tubes to solidify and permanently assume the expanded shape.
