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.
The inhibition of noise and vibration on switched reluctance motor (SRM) was study in this paper to improve the speed regulation system. Nonlinear dynamic simulation model based on the SRM is studied based on torque estimation method of torque ripple. Time-varying and nonlinear characteristics of SR motor, speed controller for closed-loop system using a fuzzy PID controller for speed adjust, the simulation results show that the system has good torque ripple effect.
