Study on Dual-Rotor Permanent Magnet Induction Motor and Performance

摘要

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