【摘要】：同步磁阻電機具有價格低廉、加工簡單、結(jié)構(gòu)可靠以及轉(zhuǎn)矩密度較高等優(yōu)點,近年來在一些低成本交流調(diào)速領(lǐng)域得到了關(guān)注。然而,同步磁阻電機待優(yōu)化參數(shù)眾多,優(yōu)化設(shè)計困難,且電機固有功率因數(shù)低、轉(zhuǎn)矩脈動較大。研究同步磁阻電機的設(shè)計方法,以及結(jié)構(gòu)參數(shù)對電機性能的影響,對于推廣其在工業(yè)領(lǐng)域的應用,具有十分重要的意義。本文首先總結(jié)了同步磁阻電機的常規(guī)設(shè)計方法,指出每種設(shè)計方法的實現(xiàn)流程,分析其優(yōu)缺點及適用條件。進而提出一種電機性能的快速預測方法,適合電機結(jié)構(gòu)參數(shù)的前期初步設(shè)計。進而研究了電機結(jié)構(gòu)參數(shù)對性能的影響,詳細討論了同步磁阻電機的極對數(shù)、裂比、繞組形式、定子鐵芯以及轉(zhuǎn)子鐵芯的設(shè)計規(guī)律,為同步磁阻電機的優(yōu)化設(shè)計提供了參考。最后將同步磁阻電機的定轉(zhuǎn)子與開關(guān)磁阻電機的定轉(zhuǎn)子分別組合,得到四種不同結(jié)構(gòu)形式的電機,研究了四種電機的性能差異及各自優(yōu)勢。并對比了同步磁阻電機與永磁輔助同步磁阻電機,詳細討論了兩種電機的工作特性。
[Abstract]:Synchronous reluctance motor has many advantages, such as low cost, simple processing, reliable structure and high torque density. In recent years, it has been paid attention to in some low-cost AC speed regulation fields. There are many parameters to be optimized for synchronous reluctance motor, so it is difficult to optimize design, and the inherent power factor is low and torque ripple is large. The design method of synchronous reluctance motor and the influence of structure parameters on the performance of synchronous reluctance motor are studied. This paper summarizes the conventional design methods of synchronous reluctance motor and points out the realization flow of each design method. The advantages and disadvantages and applicable conditions of the motor are analyzed. Then a fast prediction method of motor performance is proposed, which is suitable for the preliminary design of motor structural parameters, and the influence of motor structural parameters on performance is also studied. The pole logarithm, split ratio, winding form, stator core and rotor core of synchronous reluctance motor are discussed in detail. It provides a reference for the optimal design of synchronous reluctance motor. Finally, the stator and rotor of synchronous reluctance motor and the stator and rotor of switched reluctance motor are combined separately to obtain four kinds of motor with different structure. The performance differences of four kinds of motors and their respective advantages are studied. The synchronous reluctance motor and the permanent magnet auxiliary synchronous reluctance motor are compared, and the working characteristics of the two kinds of motors are discussed in detail.
