自啟動同步磁阻馬達之動態方程式建立及特性分析

Abstract

本文利用能量法搭配繞組函數，針對自啟動同步磁阻馬達之動態方程式進行推導，於轉子座標系及定子座標系之動態方程式，均有進行推導及呈現，接著針對推導出來之動態方程式進行驗證，確認其正確性。動態方程式經過驗證後，將其應用於作為輔助有限元素法的工具，可使用於馬達參數的計算，以及力矩成份的分離；接著將此動態方程式用於推導最大功因控制法及最大力矩控制法之驅動法，並以模擬及實驗數據佐證提出之理論。

This thesis presents a derivation of dynamic equation of line-start synchronous reluctance motor with respect to both rotor reference frame and stator reference frame. The derived equations are verified to ensure their correctness. After verified, the dynamic equation is used as an auxiliary tool in finite element analysis to measure the motor parameters and to decompose the component of electric torque. Finally, the maximum torque control algorithm and maximum power factor control algorithm are derived based on the dynamic equation. The proposed control algorithms are verified by simulation and experiment.
