Introduction

Different from regular PM machines, flux modulation machines are with different stator and rotor pole numbers, and produce steady torque based on the so called flux modulation effect. The special operation principle makes flux modulation machines high-torque density and low-pulsation torque, and more design freedoms lead to many novel machine topologies for different applications. This webinar will be a summarized presentation of Flux Modulation Machines: from principle, features to topologies. After a short introduction, the Webinar will focus on machine family definition and difference with traditional machines, operation principles, and topologies. After introducing three machine major components: flux modulator, armature and excitation field, different flux modulation machine topologies will be introduced based on different rotating components. Common features will be summarized, main concerns and challenges will also be discussed. At the end, analyses, designs, and prototypes of vernier machines, a flux-modulation machine family member, will be demonstrated.

簡介如下:

与常规永磁电机不同,磁场调制电机的定子和转子极对数不同,并基于磁场调制原理产生稳定的转矩。特殊的工作原理使得磁场调制机具有高转矩密度、低转矩脉动、高设计自由度等特点,使得在不同的應用场合有许多新拓扑结构。本次会士讲堂将是磁场调制电机的简要介绍:从原理,特征到拓扑结构。首先讨论磁场调制电机族的定义以及与传统电机在工作原理和拓扑结构上的区别。然后介绍这种电机的三个主要部分:调制单元、电枢磁场和励磁磁场,并根据不同的旋转部件对磁场调制电机进行分类。同时,磁场调制电机族的共同的特点和它们面临的挑战也将被讨论。最后,将分析一种典型的磁场调制电机即游标电机。
