【摘要】:開關(guān)磁阻電機(jī)憑借結(jié)構(gòu)堅固,系統(tǒng)穩(wěn)定,容錯性能優(yōu)越及可控性高等優(yōu)點(diǎn),已廣泛應(yīng)用于航運(yùn)、家電及國防等各種場合。隨著工業(yè)4.0時代的開啟,結(jié)合了盤式電機(jī)和開關(guān)磁阻電機(jī)優(yōu)點(diǎn)的新興軸向磁通磁阻電機(jī)顯然在電機(jī)領(lǐng)域具有明顯優(yōu)勢。論文在總結(jié)國內(nèi)外現(xiàn)有軸向磁通磁阻電機(jī)設(shè)計發(fā)展的基礎(chǔ)上,對一臺6/4極軸向磁通高速磁阻電機(jī)(Axial Flux High Speed Reluctance Motor,AFHSRM)進(jìn)行了 電磁解析法和有限元法的分析設(shè)計研究。首先,論文介紹了開關(guān)磁阻電機(jī)的主要結(jié)構(gòu)及各結(jié)構(gòu)的優(yōu)缺點(diǎn),對開關(guān)磁阻電機(jī)的主要研究方法進(jìn)行了詳細(xì)闡述,并依據(jù)開關(guān)磁阻電機(jī)的電磁設(shè)計及性能參數(shù)設(shè)計的原則,對軸向磁通高速磁阻電機(jī)進(jìn)行預(yù)設(shè)計。其次,結(jié)合軸向磁通高速磁阻電機(jī)的結(jié)構(gòu)特點(diǎn),利用解析法對軸向磁通高速磁阻電機(jī)分別在定轉(zhuǎn)子極中心線對齊位置(θ_a位置)、齒槽中心線對齊位置(θ_u位置)及定子齒后沿和轉(zhuǎn)子齒前沿重疊位置(θ_1位置)這三個位置下的磁化曲線進(jìn)行計算。為計算θ_a位置的磁化曲線,要先結(jié)合該位置下磁路飽和的特性,建立電機(jī)的等效模型,再計算各磁導(dǎo)分量,分析電流、轉(zhuǎn)子位置與磁密的關(guān)系,并將結(jié)果與有限元計算結(jié)果進(jìn)行曲線對比驗證解析法的正確性。而關(guān)于θ_u位置及θ_1位置磁化曲線的計算,就要根據(jù)磁路不飽和特性及磁阻最小原理對電機(jī)的磁鏈分布特點(diǎn)進(jìn)行分析,且給出每部分磁鏈計算方法并將其解析計算結(jié)果與有限元結(jié)果進(jìn)行比較,驗證解析法的正確性。最后,利用有限元軟件Ansoft Maxwell,建立軸向磁通高速磁阻電機(jī)三維模型,在空載情況下對電機(jī)性能特性進(jìn)行仿真分析。基于以上三個關(guān)鍵位置的磁化曲線分析軸向磁通高速磁阻電機(jī)的電磁特性,并利用不同函數(shù)對三個關(guān)鍵位置磁化曲線及某一給定電流下的曲線進(jìn)行;,然后根據(jù)磁路飽和非線性的特征,建立電機(jī)轉(zhuǎn)矩的解析方程,并將最后計算結(jié)果與有限元結(jié)果進(jìn)行比較分析其合理性。結(jié)合上述電磁分析和解析計算,形成一套完整的軸向磁通高速磁阻電機(jī)的電磁解析方法,并制作相關(guān)樣機(jī)。
[Abstract]:Switched reluctance motor (SRM) has been widely used in shipping, home appliances, national defense and other fields because of its strong structure, stable system, excellent fault tolerance and high controllability. With the opening of the industrial 4.0 era, the new axial flux reluctance motor, which combines the advantages of disk motor and switched reluctance motor, has obvious advantages in the field of motor. On the basis of summing up the current design and development of the axial flux reluctance motor at home and abroad, the electromagnetic analytical method and the finite element method for the analysis and design of a 6 / 4 pole axial flux high speed magnetoresistive motor (Axial Flux High Speed Reluctance Motor,AFHSRM) are studied in this paper. First of all, the paper introduces the main structure of switched reluctance motor and the advantages and disadvantages of each structure, describes the main research methods of switched reluctance motor in detail, and according to the principle of electromagnetic design and performance parameter design of switched reluctance motor. The high speed magnetoresistive motor with axial flux is pre-designed. Secondly, combined with the structural characteristics of axial flux high speed reluctance motor, Using the analytical method to align the axial flux high speed reluctance motor at the center line of the stator and rotor pole (胃 _ a position), the slot center line alignment position (胃 u position) and the stator tooth back edge and rotor tooth front overlap position (胃 _ 1 position), respectively. The magnetization curve at the position is calculated. In order to calculate the magnetization curve of the 胃 a position, the equivalent model of the motor should be established by combining the saturation characteristic of the magnetic circuit at this position, and then the magnetic conductance components should be calculated, and the relationship between the current, rotor position and magnetic density should be analyzed. The results are compared with the results of finite element method to verify the correctness of the analytical method. For the calculation of the magnetization curves of 胃 _ s _ u position and 胃 _ s _ 1 position, it is necessary to analyze the distribution characteristics of the flux chain of the motor according to the unsaturated characteristic of magnetic circuit and the principle of minimum magnetoresistance. The calculation method for each part of the flux is given and the analytical results are compared with those of the finite element method to verify the correctness of the analytical method. Finally, the three-dimensional model of axial flux high-speed reluctance motor is established by using the finite element software Ansoft Maxwell, and the performance of the motor is simulated and analyzed under the condition of no load. Based on the magnetization curves of the above three key positions, the electromagnetic characteristics of the axial flux high speed reluctance motor are analyzed, and the magnetization curves of the three key positions and the curves under a given current are modeled by using different functions. Then, according to the nonlinear characteristic of magnetic circuit saturation, the analytical equation of motor torque is established, and the rationality of the calculation result is compared with that of finite element method. Combined with the above electromagnetic analysis and calculation, a complete electromagnetic analytical method of axial flux high speed reluctance motor is developed, and a related prototype is made.
