Thesis Work - Ageing Factors for Insulation Materials in electric machines in automotive application

Scope of the thesis work

Market competition in electro mobility is growing tougher every year. This forces the manufactures to create new and better products faster than ever before. This has resulted in increase of performance in the drivetrain with higher voltages and higher power densities. Testing and validation if these components are vital to secure a safe and reliable product for the costumer. As this is relatively new field for automotive industry, best practice of design and validation is still developing. In this project you will help us develop new test methods to determine aging factors of the insulation material in our electric machines. 

Objective of the thesis:

• Literature study: Conduct a thorough review of scientific and technical literature related to insulation materials in electric machines, categorize their aging factors and how to quantify a lifetime for the effected components.
• Review current practices: Review current practices and test setups.
• Develop test method for lifetime testing: Create test method and design setups based on the literature study and review of current practices.
• Perform calibration test and analyze test results: Run the new test method in-house in our test facilities and analyze test results to compare with pervious tests.
• Initiate implementation of new test method in next generation machines: Perform a study on how this new test method can be implemented in our next generation electric machines.
