| Popis: | In this paper, a novel computational method that can accurately calculate the skewing leakage reactance of a doubly skewed rotor induction motor is proposed. It is based on the three-dimensional finite-element models to calculate the magnetic energy stored in every section of the machine and the rotor bar currents. In addition, the magnetic saturation and magnetic variation in the axial direction are taken into account in the models. Also, the proposed method is applied to calculate the stator leakage reactances and rotor leakage reactances. The comparisons between the testing results and the computational results show that the proposed method can obtain the more accurate results than the conventional computational algorithm. |
