【摘要】：隨著當代文明社會的發(fā)展,電機早已成了提升生產(chǎn)力,改善人民生活質量的主要生產(chǎn)工具之一。磁懸浮電機的出現(xiàn)很好的解決了在轉子旋轉過程中出現(xiàn)的軸承磨損而導致軸承壽命降低、以及產(chǎn)生的機械振動和噪聲的問題。而混合式磁懸浮電機又以其采用的永磁體轉子結構減小了相對于傳統(tǒng)磁懸浮電機的空間尺寸,在提高電機的轉換效率同時,又降低了功放的損耗。然而在進一步減小磁懸浮電機的電機尺寸,優(yōu)化結構方面,只能對混合式磁懸浮電機的定子結構入手,這里通過使用單套線圈繞組的方法,既用來驅動轉子軸的轉動,又用來驅動轉子軸的懸浮。具體為采用三套獨立分布的繞組,控制轉子三個方向的懸浮,同時三套繞組可以共同作用組成一個旋轉的磁場驅動電機旋轉,這樣就可以在定子上進一步減小電機的尺寸。本文對混合式磁懸浮電機進行了結構設計與電機徑向控制驅動的研究,對其結構設計參照了傳統(tǒng)的電機設計,對混合式磁懸浮電機的徑向控制驅動的開發(fā)主要從控制驅動電路和軟件程序入手。具體工作包括如下幾個部分:對混合式磁懸浮電機構造和運作原理進行了簡單介紹,分析了混合式磁懸浮電機的電磁機理,運用虛位移原理,建立混合式磁懸浮電機徑向懸浮力方程。對混合式磁懸浮電機的結構設計,主要分為徑向懸浮電機定、轉子結構參數(shù)確定,軸向懸浮用電機定、轉子結構和電磁鐵參數(shù)。利用Ansoft電磁場有限元分析軟件對感應磁場進行分析,得出主要部件磁場分布情況以及磁懸浮力與位移、其他控制參數(shù)的變化關系�；趯旌鲜酱艖腋‰姍C的結構設計的基礎上,對其徑向控制驅動硬件進行設計,主要分為基于SVPWM技術的電機旋轉驅動硬件設計、基于全橋功放的懸浮硬件設計。隨后對軟件控制流程做了簡要說明。搭建混合式磁懸浮電機相關的實驗平臺,進行相關實驗分析,實驗結果基本符合預定要求。
[Abstract]:With the development of modern civil society, motor has already become one of the main production tools to enhance productivity and improve people's quality of life. The appearance of maglev motor has solved the problems of bearing wear during rotor rotation, which leads to the decrease of bearing life, mechanical vibration and noise. The hybrid maglev motor reduces the space size compared with the traditional maglev motor because of its permanent magnet rotor structure, which not only improves the efficiency of the motor conversion, but also reduces the loss of power amplifier. However, in order to further reduce the size of the motor and optimize the structure of the maglev motor, the stator structure of the hybrid maglev motor can only be started with the method of single coil winding, which is used to drive the rotation of the rotor shaft. It is also used to drive the suspension of the rotor shaft. In particular, three sets of independent distributed windings are used to control the suspension of the rotor in three directions. At the same time, the three sets of windings can work together to form a rotating magnetic field to drive the motor rotation, which can further reduce the size of the motor on the stator. In this paper, the structure design and radial control drive of hybrid maglev motor are studied. The structure design of hybrid maglev motor is based on the traditional motor design. The development of radial control drive of hybrid maglev motor mainly starts with control drive circuit and software program. The specific work includes the following parts: the structure and operation principle of hybrid maglev motor are introduced, the electromagnetic mechanism of hybrid maglev motor is analyzed, and the principle of virtual displacement is used. The radial suspension force equation of hybrid maglev motor is established. The structure design of hybrid maglev motor is mainly divided into radial suspension motor stator rotor structure parameter determination axial suspension motor stator rotor structure and electromagnet parameters. The magnetic field distribution of the main components and the relationship between the magnetic suspension force and displacement and other control parameters are obtained by using the Ansoft electromagnetic field finite element analysis software. Based on the structure design of hybrid maglev motor, the radial control drive hardware is designed, which is mainly divided into two parts: motor rotation drive hardware design based on SVPWM technology and suspension hardware design based on full-bridge power amplifier. Then the software control flow is briefly explained. The related experimental platform of hybrid maglev motor is built and the experimental results are basically in accordance with the scheduled requirements.
