Comparison of end of line tests for serial production of electric motors in hybrid truck applications

This paper focuses on the steps to compare methods to detects faults at the end of line (EOL) testing section after the assembly of permanent magnet synchronous motors (PMSM) for automotive, especially truck applications. In detail two philosophies were discovered in case of using end of line test benches to check all functionalities of an electric motor after all assembly steps. The comparison is a practical approach and involves three parts to investigate on the passive end of line test bench as a sufficient method to detect all critical faults and the performance of PMSMs.
