本文提出了轴向磁场电机的不同配置，其特点是转子极数与定子齿数和线圈数之比非常大，适用于低速直接驱动牵引应用。该电机具有带轮辐式永磁体的单个转子，并且定子齿包括辅助槽，辅助槽的功能是增强与转子相互作用的定子磁动势的高极性分量以产生净转矩。电机可以构造成具有三相或两相，在这种情况下，由于相之间缺乏耦合和相对大的相电感的组合效应，它们固有地表现出对故障的高容限。一个初步的比较仿真研究表明，传统的参考永磁同步电机的性能改善。
This paper proposes different configurations of axial-field machines featuring a very large ratio of the number of rotor poles to stator teeth and coils suitable for low-speed direct-drive traction applications. The machines have a single rotor with spoke-type permanent magnets and the stator teeth include auxiliary slots, the function of which is to enhance the high-polarity component of the stator magnetomotive force interacting with the rotor to produce a net torque. The machines can be constructed with three or two phases, in which case they inherently exhibit high tolerance to faults due to the combined effect of a lack of coupling between phases and a relatively large phase inductance. A preliminary comparative simulation study shows performance improvement over a conventional reference permanent magnet synchronous machine.
