摘要
在分析异步电动机的运行机理的基础上，运用变分法对异步电动机进行了节能分析，并推导出能耗最小的起动电流曲线iq1和起动时tf；若以其作为起动过程的控制方式，可达到很好的节能效果．最后通过仿真验证了该控制方法的高效性．
First the running mechanical theory of an induction motor is analyzed; second by using different-method, energy saving of an induction motor is studied; following, the starting current curve and starting time are calculated, which can make the losses of a motor a minimum. If using it as the control way of starting process, much better energy saving effect will be required. Finally, a simulation verifies the validity of the control method.
