<p>Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.</p><p>The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.</p><p>The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.</p><p>The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.</p><p>An analysis has been made on frequency inverters, soft starters and shaft power monitors. Fail reports for the year 2007 have been reviewed. Faults that have been detected have been sub-mitted by type and size. The testing has been divided into various phases of error. A time pre-cision has been established to show the time of the test stages. The distinction has been made to provide a picture of where and when errors occur during the testing.</p><p>A logging test has been carried out on the largest frequency inverter types to determine the characteristics of frequency inverters when tested with load by today's test method. It has also carried out a logging test with an artificial load. An analysis is made on a test machine that is under construction, which today is called PEBB test.</p><p>The conclusions to be drawn from the analyses and tests carried out, in order to meet the company's objectives, and answer the project's problem is that it is possible to make the end of line test more efficient. The end of line test can be more efficient by combining the strength of the PEBB test, which is its measurement equipment, with the artificial load method where the frequency inverter is tested as it is expected to serve at the final customer. This can in-crease the outflow of tested products and maintain Emotrons requirements for quality.</p>
