摘　　要：通过麦克斯韦方程组推导了异步电机磁场分布的微分方程,给出了采用有限元法求解方程的基本思路和编程算法,根据磁场的分布得出了电机转矩及轴向合力的计算公式和差分方程。此方法能够快速有效地判断出不同的输入波形对电机运行的影响,并能准确地计算出电磁转矩和轴向合力。The differential equations of the magnetic field distribution for induction motor were derived by Maxwell＇s equations, then, the solution by the Finite Element Method was discussed. Finally, the formulas to calculate the torque and the axial force were obtained, This method could estimate the effect of different input waveforms to the induction motor quickly and efficiently, capable of acquiring the torque and axial force accurately.
