This Bachelor’s thesis was done for the Power Tools department at Mirka Ab. The aim of this thesis was to study different ways to accelerate the lifetime of the speed controller in the Deros sander and provide a standardized test method for accelerated testing. The reason for using a standardized test method is to compare earlier designs against new ones in the product development process. This test method will also reveal weaknesses earlier in the development phase. The accelerating methods used were: constant stress, step stress and cyclic stress. All these tests were performed in an environmental chamber. The factors used for accelerating the product were temperature, humidity, vibration and overload. The results show that it is possib...
