| 摘 要： | 在二维电磁场的数学模型基础上,建立二维电磁场有限元的离散方程,利用"场"的方法代替了以前"路"的方法及"场路结合"的方法.算例表明,其算法可有效提高计算精度.尤其对电机的关键部分——齿层区域的磁场精确求解比较有意义,可以根据磁密的饱和程度来精确选材.

| Abstract: | Discrete equations of two-dimensional model of electromagnetic fields were built by using FEM based on two-dimensional mathematical model of electromagnetic fields.The field method was used instead of path and combination of both methods.The example showed that calculation accuracy could be improved effectively using this algorithm.It was significant to the magnetic field accurate calculation of motor key part tooth-layer regional.And the exact material could be selected according to the saturation precision level of magnetic field density. |
