摘要
基于空间向量积分法建立了共轴涡旋结构载流线圈的解析模型,计算了磁场及磁力,并对特殊取值下的磁场空间分布进行了数值分析和讨论。基于仿真结果,提出线圈密绕情况下的近似模型并进行了相应的误差分析。结果表明,所提模型可有效地直接对磁场分布进行近似,但需对受力近似进行一定的补偿。
An analytical model of coaxial current-carrying coils with vortex structure based on space vector integration is established in this paper. The magnetic field and force are calculated, and the spatial distribution of the magnetic field under some special values is numerically analyzed and discussed. Based on the simulation result, an approximation model of coils under dense winding condition is presented and the errors are analyzed. The result indicates that this model can effectively approximate magnetic field distribution directly but needs some compensation to approximate the force between coils.
