本文在考虑交流损耗的情况下比较了四种类型的超导直线电机的力密度。损失的有限元模型，其中几种方法来降低模型的复杂性相结合，以实现低计算时间进行评估。进行参数搜索以确定所有电机类型的最大可实现力密度，其中工作温度、几何参数和通过超导线圈的峰值电流是变化的。结果表明，每种电机类型的最佳匝数和2500 N/dm 3左右的力密度可以实现所有四种电机类型在20 K。
This paper presents a comparison of the force density of four types of superconducting linear motors, taking into account the ac losses. The losses are evaluated by finite-element models, in which several methods to reduce model complexity are combined to achieve a low computation time. A parametric search is performed to determine the maximum achievable force density of all motor types, in which the operating temperature, geometric parameters, and peak current through the superconducting coils are varied. Results show the optimum number of turns for each motor type and that a force density around 2500 N/dm3 can be achieved by all four motor types at 20 K.
