摘要
通过对两相异步电机绕组结构的分析,在理想化假设的情况下推导了两相电机的电磁关系,建立了电机在任意速旋转坐标系dqn下的通用数学模型,并在分析电机数学模型的基础上,应用搭建模块法建立了Matlab/Simulink软件环境下两相异步电机的动态模型.并以实际应用中的小功率电机为例,对电机运行进行了仿真分析.对其启动后突加负载及带负载启动等多种瞬态过程进行了仿真计算.仿真结果表明应用此数学模型对电机运行过程进行仿真具有较高的精度、较好的通用性等优点,具有一定的实用价值.
Based on analyzing the winding structure of two-phase asynchronous motor,the electrical and magnetical relationship has been deduced under an ideal assumption.The universal mathematical model under dqn coordinate turning at arbitrary angular velocity has been established.The simulation case of the two-phase asynchronous motor has been constructed under Matlab/Simulink environment.The starting and loading conditions have been simulated.The results demostrate that the two-phase asynchronous motor has characters of high accuracy and stability.
