摘要
文章从节电的角度对异步电动机的功率选择进行论述,指出按效率最高时的负载率选择电动机功率是一种近似的计算方法,作者提出了一种以临界功率为参数的电动机功率计算法,用此法选择电动机功率能确保电机损耗最小。
Based on the pointviews of saving on electricity, thispaper has discussed the power selection of asynchronous motor. It pointsout that the calculating method, to select the power of motor according tothe load rate when the motor has the highest efficiency, is a approximateone. Author has proposed a new calculating method which uses the criticalpower of motor as the main parameters. When using this method to selectthe power of motor, we can make the motor's wasted power lowest.
