高磁场和线圈电流引起的强电磁力是超导储能系统中的一个严重问题。针对这一问题，我们提出了力平衡线圈（FBC）的概念，它是一种应用于超导磁储能系统的螺旋绕制环形线圈。本文给出了螺旋绕组的变化，以降低结构要求。根据位力定理，讨论了超导磁储能线圈形状与结构要求之间的关系。根据这一结果，FBC可以通过选择最佳极向匝数来最小化工作应力。
Strong electromagnetic force caused by high magnetic fields and coil current is a serious problem in superconducting magnetic energy storage (SMES) systems. In facing this problem, we proposed the concept of the force-balanced coil (FBC) which is a helically wound toroidal coil applied to SMES. This paper shows the variations of the helical windings in order to reduce structure requirements. We discuss the relationship between the shape of SMES coils and the structure requirements based on the virial theorem. From this result, the FBC can minimize the working stresses by selecting the optimal number of poloidal turns.
