In this article, it is pointed out that calculating induced electric field caused by variable magnetic field in constantvelocity by analogical method is a simple method.
用类比方法来计算以恒定速率变化的磁场产生的感应电场是一个简便的方法。

By means of study on velocity field constant in flue, a method used to measure average velocity of flue gas was presented.
Then a vector control method with speed closed-loop and magnetic linkage closed loops put forward, which is based on the constantvelocity by means of stator flux-oriented vector control.
