变频器—三相异步电动机调速系统的计算机辅助设计方法

CAD of variable-frequency induction motor speed regulation system

建立了变频器及恒磁通变频调速三相异步电动机的数学模型 ,从而提出交流调速系统计算机辅助设计方法。通过示波器测试系统瞬态响应与数值仿真结果相符 ,验证该数学模型和设计方法是可行的。

We propose the mathematical models of frequency converter and variable-frequency induction motor,respectively. Thus, the CAD method for variable-frequency induction motors speed regulation system is provided. Agreement of the instantaneous responses of the system detected by oscilloscope and that simulated via Simulink verifies the feasibility of the mathematical models and design method.
