Abstract :
The FEM discrete equations of two-dimensional electromagnetic fields are created based on two-dimensional mathematical model of electromagnetic fields, with the field method instead of path and with the combination of both methods. And the example shows that calculation accuracy is improved effectively by this algorithm, which is significant to the accurate magnetic field calculation of the key part of motor - tooth region. And the exact material can be selected by the saturation level of magnetic field density.
