Preparation of cable end before stator winding (English)
Abstract [en]

At Uppsala university scientists have during the last years developed and built wave energy converters. This project is called "Lysekilsprojektet". The development has come so far that they are currently investigating how to gain profit in a mass production. For that reason they want to automate as many steps in the production as possible.

The winding of the stator is one part that is being automated using industry robots. The stator is cable wound unlike many other generators. The stator consists of many thin stator sheets that have been stacked. These stator sheets have cable slots where the cables pass through. This can lead to the cable getting stuck during winding. To avoid this the shape of the cable end has to be changed. This report investigates methods to automate the process of preparing the cable end.

Experiments show how the cable insulation acts when heated and cooled. Different methods are tested to see how the insulation can be pulled out and reshaped. The methods presented have showed good results and are worth to continue to develop. The results have achieved the set requirements. The project leader has shown interest to build the presented concept tools. This report also shows that it is possible to save three hours and 40 minutes per complete stator winding by using a separate robot to carry out the preparation instead of the winding robots. This could reduce about 20 % of the total winding cycle. If this preparation were to be carried out manually it would take about five hours and ten minutes for each stator.
