碩士 === 國立中山大學 === 電機工程學系研究所 === 93 === This thesis presents a systematic scheme to design the optimal efficiency operations and axial force control of a single-sided permanent-magnet axial-flux motor with center pole (SPAMC) through the detailed mathematical model and operational analysis. According to the rotating magnetic field theory combining with the recoil line characteristics of permanent magnet and the magnetic equivalent circuit, appropriate projection of the stator currents to achieve the optimal efficiency operations and axial force control can be realized. From these evaluations, a feasible operational guidance for SPAMC field oriented control (FOC) framework can be successfully developed. Finally, based on the proposed operational scheme, a DSP-based drive system has been successfully implemented, and the optimal efficiency operations and axial force control objectives can be achieved.
