ABSTRACT

In this paper, dual-rotor permanent magnet induction motor(DRPMIM) is studied to improve performance of usual induction motor(IM). Two-dimensional finite element model for DRPMIM is established by Maxwell Ansoft software, and electromagnetic characters of that was analyzed.Based on the rotating coordinate system, the mathematical model concerning DRPMIM, performance curves under the different load are obtained. The final simulation analysis results are in good agreement with the theoretical predicting results, which can be used to afford a theoretical basis to design the DRPMIM in the future. Compared with the conventional asynchronous motor, the DRPMIM can effectively improve power factor and efficiency.
