碩士 === 國立高雄應用科技大學 === 製造與管理外國學生碩士專班 === 103 === This thesis presents a novel of two-phase micro axial switched reluctance motor (μASRM) using common pole, which intends to improve the output torque characteristic. The stator is established by six poles, with two center poles no copper windings (common poles) and four poles at the ends having windings. The rotor is composed of ten poles. The proposed motor is generated by using a combination topology optimization method and finite element analysis (FEA) to reduce torque ripple. Two proposed design of 1.5mm-diameter and 2.25mm-length two-phase μASRM using common pole are analyzed electromagnetic by JMAG software. The results show that, the first design has average torque increases 8% and torque ripple reduces 39% as comparing with fan-shape design. The torque ripple of the second design reduces 35%; however average torque increases 29% respectively. In order to verify the proposed design process and the output torque characteristics, the motor is fabricated, assembled and tested. Based on the previous results, the LIGA (German acronym for lithography, electroforming, and molding) processes are used to fabricate micro parts and then micro motor is successful assembly. Furthermore, from supported by laboratory prototype, the output torque, back electromagnetic force (EMF), speed of motor has tested.
