提出了一种新型直线永磁电机--模块化直线磁链反转电机。这对于高可靠性的城市轨道交通来说尤其具有吸引力。它的永磁材料和电枢绕组设置在动子(列车)中，而长的定子(轨道)由铁组成，从而提高了效率，降低了成本。该电机的关键是引入了容错齿的概念，以提供所需的相之间的解耦。介绍了该电机的结构和特点，并进行了优化设计。通过有限元分析，验证了该电机的优越性和有效性。分析结果表明，所提出的M-LFRPM电机既保留了传统LFRPM电机的优点，又提高了容错能力。
A new linear permanent-magnet (PM) motor, termed as modular linear flux-reversal PM (M-LFRPM) motor, is proposed. This is particularly attractive for high reliability urban rail transit. Its PM materials and armature windings are set in the mover (train), while the long stator (rail) is composed of irons, hence improving efficiency and reducing cost. The key of the proposed motor incorporates the concept of fault-tolerant teeth to provide the desired decoupling among phases. The structure and features of the proposed motor are presented, and an optimal design is performed. By using finite element method, the advantages and validity of the proposed motor are verified. The analysis results show that the proposed M-LFRPM motor not only retains the advantages of the conventional LFRPM motor, but also improves its fault-tolerant capability.
