摘要

横向磁通电机(tfm)具有电流方向与转子运动方向相对应的结构和环形定子绕组。tfm的优点是单位体积力密度高，效率高，因为没有绕组端匝的电阻损失，磁路与电路分离。作者设计了两种TFM:变磁阻型和永磁屏蔽型。带pm屏蔽的TFM定子齿上有一块永磁体，可以屏蔽气隙漏磁，从而提高功率密度。通过对这些电机进行二维和三维有限元分析以及实验测量，证明了永磁屏蔽的作用。

A design of transverse flux motor with permanent magnet shield

Transverse flux motors (TFMs) have a structure in which the direction of the current corresponds with the motion direction of the rotor, and a ring-shaped stator winding. The advantages of TFMs are high force density per volume and high efficiency because the resistance loss of winding end-turns is absent and the magnetic circuit is separated from the electric circuit. The authors designed two kinds of TFM, which are a variable reluctance type and a permanent magnet-shield type. The TFM with the PM-shield has a permanent magnet on the teeth of stator to shield it from airgap leakage flux, thereby increasing the power density. By analyzing these motors using 2-D and 3-D FEM and experimental measurements, the authors show the effect of the PM-shield.
