Prediction of the overall characteristics for high power permanent magnet synchronous motor with multi phase units

Testing of Multi Phase High Power Permanent Magnet Synchronous Motor (PMSM) having multiple units is a difficult task. In this paper, prediction problems to obtain the overall characteristics for such motor under limited experimental conditions have been analyzed. A simplified testing model of the motor is established for testing of the overall characteristics and calculation methods were studied. Finally, some valuable conclusions resulting from the analysis are provided.
