在低速应用中，常提出可变磁阻永磁电机，这是由于其有效利用磁体材料和高转矩密度。这在大型线性应用中变得更加重要，其中转换器比定子长。然而，这类机器通常经历非常低的功率因数。本文提出了一种V形磁通集中的版本的一个顺极线性游标混合永磁电机，并比较它的表面安装的磁铁的变体。使用有限元分析验证了两个实验室的原型，它表明，磁通集中的版本增加气隙磁通密度，这可能会导致力密度和效率的改善，或可用于增加操作功率因数。
In low-speed applications, variable-reluctance permanent magnet machines are often proposed due to their efficient use of magnet material and high torque density. This becomes even more important in large linear applications, where the translator is longer than the stator. Often, however, very low power factors are experienced by this class of machines. This paper proposes a V-shaped flux concentrated version of a consequent pole linear Vernier hybrid permanent magnet machine and compares it to a surface-mounted magnet variant. Using finite-element analysis validated by two laboratory prototypes, it is shown that the flux-concentrated version increases the airgap flux density, which potentially leads to an improvement in the force density and efficiency or can be used to increase the operating power factor.
