The Design and Analysis and Implementation of the High PerformanceBrushless DC Wheeled Motor System

It is presented in the paper that the strategy of harmonics injection in both EMF and current and the strategy of leading angle current feedback control are adopted in order to improve performances of the driving system in the electric vehicle. The hardware designs of the brushless DC wheeled motor system are first introduced briefly, but the design data and the design procedure for the motor in this system are given in detail. The theories and experiments on the two strategies presented above are described and analyzed detailedly. Finally, the definite conclusions are given correspondingly.
