本文旨在研製具弱磁控制的雙組三相永磁式同步電動機及其驅動器。電動機的定子設計為24槽集中繞線圈且轉子為20極的铷鐵硼永久磁鐵，驅動器的輸入電壓為直流24V，為了提升系統直流鏈電壓利用率，本系統採用電壓空間向量脈波寬度調變(VSVPWM)做為系統驅動控制，驅動器架構採用雙組三相三臂型變頻器電路以減少定子繞線線徑同時提高耐流能力，控制策略採用雙組座標軸系統轉換及轉子磁場導向控制，以完成轉速及電流閉迴路控制與轉子旋轉座標軸的直軸電流控制策略，達到提高效率及轉速響應的目的。訊號回授方面，本文雙組三相永磁式同步電動機使用解角器(resolver)及解角器數位轉換器(Resolver to Digital Converter, RDC)作為轉子磁極角位置及轉速的回授，並使用電流偵測元件(current sensor)回授電動機側的雙組三相電流，將回授電流配合轉子旋轉座標系統轉換至交軸(quadrature-axis)、直軸(direct -axis)後做電流閉迴路控制，以提高轉矩的響應。永磁式同步電動機的反電動是會隨著轉速提升而增高，直流輸入電壓為固定的情況下會無法使電流注入至電動機的定子線圈，本文採用轉子旋轉座標軸的直(d)軸電流控制策略以提高轉速範圍。
本文使用有限元素分析軟體JMAG作三相永磁式同步電動機的磁路設計及反電動勢分析，完成電動機幾何尺寸、鐵心及磁石等材質的設計，並經由量測平台實測參數，以驗證永磁式同步電動機參數之正確性。採用Matlab/ Simulink 軟體模擬雙組三相變頻器及雙組三相永磁式同步電動機之驅動系統，以驗證控制系統的可行性。硬體部分以德州儀器公司的數位信號處理器TMS320F28075做為系統控制核心，其中雙組三相變頻器的脈波寬度調變控制與q、d軸下的轉速及電流閉迴路控制皆由軟體程式完成。本文已完成1.8 kW的雙組三相永磁式電動機驅動系統雛形，並完成弱磁控制策略。

This thesis presents the design and implement of double-three-phase permanent-magnet synchronous motor (PMSM). A digital signal processor TMS320F28075 is used as the control core for controlling the entire system and two sets of three-phase three-leg inverters. To improve the utilization of system’s dc-link voltage, the voltage space vector pulse wave width modulation (VSVPWM) was adopted to the system. The feedback of rotor position and speed is implemented by the resolver. Then use the current sensor to feed back the dual three-phase current, and transfer it into quadrature-axis and direct-axis by using Park's transformation method for the closed-loop current control to increase the efficiency and speed response. In order to exceed the rated speed 800 rpm, the minus current commend of quadrature-axis of control strategy is applied to the control system.
The flux and induction voltage of synchronous motor are analyzed by the two-dimensional finite-element field analysis software JMAG. Matlab/Simulink is used to simulate the proposed PMSM system and verify the feasibility of the control strategy. A prototype of 1.8kW double-three-phase synchronous motor is developed. Simulation and experimental results are verified by the analysis.
