【摘要】 本文提出了一种异步电动机最佳效率的控制方法,这种方法从电机的损耗模型出发,直接检测电机的铜损和铁损,调整电机定子端的输入电压,从而得到一定频率、不同负载时电机运行于最佳效率的输入电压值,使电机保持最佳效率运行:并用MATLAB的SIMULINK仿真工具进行了仿真实验,其结果表明,这种方法控制直接、简单,能够达到很好的节能效果。更多还原

【Abstract】 This paper presents a new method for asynchronous motor running with optimal efficiency based on motor loss model. Adjust the input voltage by detecting the iron loss and copper loss of motor directly, and the input voltage of motorrunning with optimal efficiency obtained In this case, motor can keep running with high efficiency: The control of this method is direct, simple and available, which is verified by the emulational experimental results with SIMULINK of the MATLAB.更多还原
