【摘要】 提出一种进行模拟计算电动机启动过程中各参数的新方法。利用电机运行理论,结合物体定轴转动定律,推导出电机运行参数随时间变化的函数关系式。将计算公式离散化后,对电机启动过程运行规律进行求解。实例计算了一种型号潜油三相电动机启动时电动机定子电流、转子电流、激磁电流、扭转力矩、转速参数及效率参数等随时间或转差率的变化规律,其变化曲线与试验结果基本一致,说明提出的计算方法是有效、正确、适用的。更多还原

【Abstract】 New method to simulate the starting process of three phase alternative current motor is proposed and some important characters in this process are calculated.!The relationship between the value of time and that of characters in operating motor is deduced by using motor running theory and the rotating law of rigid objects.This equation is resolved by numerical calculation.In real case of starting process for a sub-oil motor of three-phases current,many parameters are calculated.The results from simulations fit with the experimental results.It is obvious that the simulation method proposed by us is correct,effective.更多还原
