提出了一种新型的双侧原边绕线磁场开关直线电机（PWFFSL），其无磁轭铁、直流磁场和电枢绕组均位于短原动机内，而长双侧副边定子仅由铁制成。此外，该电动机可以提供正弦和对称的反电动势和较小的力涟漪，因为每一相包括两个电枢线圈，其位置彼此相距180电度。因此，这类直线电机结合了线性开关磁阻（LSR）电机结构简单、成本低的优点和线性同步永磁（LSPM）电机正弦反电动势的简单控制，非常适合于长定子应用，如电梯系统。通过有限元分析（FEA），建议的双面PWFFSL电机进行了优化，并与LSR电机的基础上相同的外形尺寸进行了比较。结果表明，该电机可以提供更高的推力和更低的力涟漪。
In this paper, a new double-sided primary wound field flux-switching linear (PWFFSL) motor is proposed, in which the yokeless iron, DC field and armature windings are all located in the short primary mover, while the long double-sided secondary stator is only made of iron. Also, this motor can offer sinusoidal and symmetrical back-EMF and smaller force ripple, because each phase includes two armature coils whose positions are mutually 180 electrical degrees apart. Hence, these kinds of linear motors incorporate the merits of simple structure and low cost of linear switched reluctance (LSR) motors and simple control due to its sinusoidal back-EMF of linear synchronous PM (LSPM) motors, which are perfectly suited for long stator applications such as elevator system. By means of finite element analysis (FEA), the proposed double-sided PWFFSL motor has been optimized and compared with a LSR motor based on the same overall dimension. The results show that the proposed motor can offer higher thrust force and lower force ripple.
