Abstract

The role of reuse and recycling has become more and more important due to environmental reasons during the last years. To realize this goal, flexible automatic disassembly is needed. We have investigated a robotized work station supported by sensors as one possible solution. As an example an electrical motor has in detail been disassembled with the aim to separate the different materials. In an industrial motor the copper is situated in the stator windings and in the junction box. There are three pats in the proposed disassembly work, an inspection phase where the functionality of the motor is determined, a manual disassembly task where the junction box, the shields and the rotor are removed and finally the last part is an automatic removal of the stator windings. The focus in this paper is on the first part, the functionality test. In this test different faults of the motor is identified and a decision in made whether the motor should be repaired or disassembled. The test is performed during start-up of the motor without any load. Current, voltage, vibration and rotation sped is measured. The tested conditions results in a performance classification of the motor by Principal Component Analysis, PCA.
