有限元计算预测扭矩的准确性主要取决于离散化水平以及所采用的评估方法。存储的能量被用来衡量适当的网格密度在永磁励磁电机齿槽转矩的预测有限元模型。存储的能量和扭矩预测的能量法和麦克斯韦应力积分之间的关系进行了讨论和论证的案例研究，并提出建议，为他们的实施。>
The accuracy of the predicted torque from a finite-element calculation is determined largely by the level of discretization, as well as the evaluation method employed. The stored energy is used to gauge the adequacy of the meshing density in a finite element model for the prediction of the cogging torque in permanent magnet excited motors. The relationship between the stored energy and the torque predicted by both the energy method and Maxwell stress integration is discussed and demonstrated by case studies, and recommendations for their implementation are presented. >
