超导旋转电机在轴向磁通配置中的设计、构造和运行都强烈依赖于减小转矩脉动的能力。为了使三相全超导异步电动机的输出功率最大化，提出了优化气隙内磁通密度的新概念。该机器是在围绕中心转子分布的双边定子的基础上设计的。磁通的最佳分布和转矩脉动的最小化是由电动机的相位分布、转子条数和气隙厚度的选择决定的。通过有限元分析得到了气隙内的磁通大小，并将推导出的一些参数与实验结果进行了比较。然后，讨论了设计对转矩大小和转矩脉动的影响。
The design, construction, and operation of superconducting rotatory machines in an axial flux configuration are strongly dependent on the ability to reduce torque ripple. A new concept is presented in order to maximize the output power optimizing the magnetic flux density within the air gap of a three-phase fully superconducting induction motor. The machine is designed on a basis of bilateral stators distributed around a central rotor. The optimal distribution of magnetic flux and the minimization of torque ripple are resulting from an adequate distribution of motor phases, number of rotor bars, and choice of air-gap thickness. The magnitude of magnetic flux in the air gap is obtained by means of finite-element analysis, and some derived parameters are compared to experimental results. Then, the impact of the design on torque magnitude and torque ripple is discussed.
