基于Maxwell2D的开关磁阻电机特性仿真

摘要

采用Ansoft公司的RMxprt和Maxwell模块建立了开关磁阻电机的二维模型,并对其进行了有限元分析,得到了开关磁阻电机运行时的转矩、电流、功率等特性曲线,并且通过不同导通角的比较找到了电机运行时转矩脉动较小的控制角,这些工作为电机的实际运行控制提供了依据.%A two-dimensionnal model of the switched reluctance motor was established by using RMxprt and Maxwell2D from Ansoft corporation. Through finite element analysis of this SRM the torque, current, power curve of the switched reluctance motor were given at the run-time. By comparing different conduction angle, could get the control angel at which the motor' s torque ripple was smaller. All this work provided a basic foundation for the actual operation of the motor control applications.
