Prediction of 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.
