Abstract

Transverse flux machines (TFMs) originally have heteropolar arrangement of permanent magnets (PMs) on the rotor and a ring winding on the stator. These conventional TFMs are single stack single phase machines. To realize a multi stack polyphase machine, multiple single phase TFMs have to be stacked together. As an alternative to conventional multi stack polyphase TFM (T₀), a single stack polyphase TFM (T₁) is proposed in this paper. The proposed single stack polyphase TFM has homopolar arrangement of PMs on the rotor and a polyphase winding on the stator. Both the machines (T₀ and T₁) are analyzed using magnetic equivalent circuit (MEC) and finite element analysis (FEA). The machines are compared on the basis of their structure, material requirement, parameters and performance. The outcome of the comparative study of the TFM topologies under consideration, leads to correlation between structure of the TFMs and their performance. In this work benefits and limiting factors of the proposed topology over the conventional topology are discussed. Prototype of the proposed machine is developed and experimental validation of the proposal is presented.

摘要

横向磁通电机（TFM）最初在转子上具有永磁体（PM）的异极布置，在定子上具有环形绕组。这些传统的TFM是单堆单相机器。为了实现多堆叠多相电机，必须将多个单相TFM堆叠在一起。作为传统的多堆多相TFM（T ₀）的替代方案，本文提出了一种单堆多相TFM（T ₁）。提出的单堆多相TFM在转子上具有PM的同极排列，在定子上具有多相绕组。这两台机器（T ₀和T ₁）使用磁等效电路（MEC）和有限元分析（FEA）进行分析。根据机器的结构，材料要求，参数和性能对机器进行比较。所考虑的TFM拓扑的比较研究的结果导致TFM的结构与其性能之间的相关性。在这项工作中，讨论了所提出的拓扑相对于传统拓扑的优点和限制因素。开发了所提议机器的原型，并提出了该提议的实验验证。
