Test Setup with a Permanent Magnet Synchronous Machine for Efficiency Maps of an Electric Vehicle

This paper presents activities connected with the realization and putting into service of a 100 kW frequency controlled permanent magnet synchronous machine (PMSM). Electromagnetic interference problems, mechanical problems and theirs solution is presented. The tuning and functionality of the control algorithm is described and the results of the experiments are presented. The test setup is used to verify efficiency map calculation and measurement for an electric vehicle drive system.
