    • 本論文提出一間極式磁致動器。三維磁致動系統係以磁致動器磁化磁性藥物，並感應一磁力於磁性藥物上。藉由使用感應於磁性藥物上的磁力導引藥物至靶的位置。
    然而，傳統磁致動器需增加相電流來增強感應於藥物上的磁力，亦造成較大的功耗損失。本論文提出之間極式磁致動器，俾使降低相電流同時增強感應於藥物上的磁力。此外，藉由使用有限元素法(FEM)軟體COMSOL®，俾以分析磁致動器的磁場與計算感應於藥物上的磁力。
    最後，實做一間極式磁致動器的雛型結構以驗證所提出之間極式磁致動器能產生較強的磁場。

    This thesis presents an interpole actuator for the 3-D magnetic actuating system. In the 3-D magnetic actuating system, the magnetic actuator generates the magnetic field to magnetize the magnetic drug, and then the magnetic force is induced on the magnetic drug. However, the magnetic force is enhanced by increasing the phase current, which causes greater power consumption. Therefore, the interpole actuator is proposed in order to reduce the phase currents while increasing the magnetic force induced on the magnetic drug. Using the finite element method (FEM), the magnetic field of the magnetic actuator is analyzed. Moreover, the magnetic force induced on the magnetic drug is calculated.
    Finally, the prototype of the proposed interpole actuator for the 3-D magnetic actuating system is implemented to verify that the magnitude of the magnetic flux density vector in the proposed interpole actuator is greater than that in the conventional actuator.
