摘　　要：本文对异步电动机起动过程中出现的附加同步转矩作了简化分析，提出了一种简化实用的计算方法，根据此方法只需依据电机的似稳态起动特性的电流和相应的等效电路的参数.即可对起动过程中可能出现的同步附加转拒作出定量分析，为设计电机的起动性能提供了一种有效的计算方法，并通过试验对一台电动机起动的计算实例进行了实验验证，验证结果表明此简化计算方法具有足够的精确度，完全可以满足工程实用设计，从而非常简便地解决了起动过程中同步附加特拒的计算这一难题。The synchronous additional torques of induction motors during their starting are analyzed simply. A new method which is very simplified,convenient and practical in the analysis and calculation of the synchronous additional torques of induction motors is obtained for the first time. The torques can be calculated very simply and conveniently with this method only on the basis of the parameters of stator and rotor and the starting current of quasi-steady state of motors- The analysis and method are rerified through a real example of calculating and measuring are made on a motor. bo the difficult problem of ca1culating simply the synchronous torques is solved with great satisfaction.
