本文介绍了异步电动机驱动力矩和风机阻力矩的计算公式以及使用定积分中值定理分段精确计算启动特性的方法。这个方法较目前工程上使用的图解法和解析法可以得到更加精确的结果。文后附有例题。
This paper introduces the formulas for calculating the driving torque and the drag torque of induction motors and the method for accurately calculating the starting characteristics by using the definite integral median value theorem. This method can get more accurate results than the graphical and analytical methods currently used in engineering. Text attached with examples.
