对于轨道相对较宽且速度较高的情况，无刷电机印刷电路定子的导电轨道中的涡流损耗可能会很大。这项研究提出了一种确定印刷电路涡流损耗的数值技术。它基于三维 (3-D) 有限元分析和二维有限差分的混合。经过实验验证的技术速度快、相当准确，并且其计算资源要求非常适中。
Eddy-current losses in the conducting tracks of printed circuit stators of brushless motors may be significant for cases where tracks are relatively wide and speed is high. This study presents a numerical technique to determine printed circuit eddy-current losses. It is based on a hybrid between three-dimensional (3-D) finite-element analysis and 2-D finite difference. The experimentally validated technique is fast, reasonably accurate and its computing resource requirements are very modest.
