4、相比,它具有本錢低、結(jié)構(gòu)簡(jiǎn)單、易于制造 等優(yōu)點(diǎn).但它也有一些缺點(diǎn),比方小的起動(dòng)轉(zhuǎn)矩,表現(xiàn)不佳的速度限制在輕載和低 功率因數(shù).Ansoft作為世界領(lǐng)先的電磁有限元分析軟件,Maxwell已廣泛應(yīng)于電氣設(shè)備行業(yè),RMxprt作為Ansoft最重要的一個(gè)模塊,廣泛應(yīng)用在工程電磁場(chǎng), 它可以優(yōu)化前期工程的設(shè)計(jì).然后我們可以生成一個(gè)合理的2 d / 3 d有限元分析模型.可自動(dòng)加載幾何和自動(dòng)定義的各個(gè)局部材料,給電動(dòng)機(jī)的邊界條件時(shí), 勵(lì)磁電源等等.在本設(shè)計(jì)報(bào)告中,我們利用Ansoft Maxwell進(jìn)行建模.詳細(xì)分 析步驟和過程,根據(jù)給定的設(shè)計(jì)參數(shù)結(jié)合上課所學(xué)習(xí)的知識(shí),在Ansoft Maxwell14

5、中進(jìn)行仿真和計(jì)算,來驗(yàn)證電機(jī)設(shè)計(jì)的合理性.四設(shè)計(jì)分析根據(jù)給定的設(shè)計(jì)數(shù)據(jù),經(jīng)過一系列的計(jì)算,為后續(xù)進(jìn)行仿真設(shè)計(jì)打下了根底, 三相異步電動(dòng)機(jī)電機(jī)設(shè)計(jì)是個(gè)復(fù)雜的過程, 需要考慮的因素、確定的尺寸和數(shù)據(jù) 很多.與單相異步電動(dòng)機(jī)相比,三相異步電動(dòng)機(jī)運(yùn)行性能好,并可節(jié)省各種材料. 根據(jù)轉(zhuǎn)子結(jié)構(gòu)分類,可分為籠式和繞線式,本設(shè)計(jì)選擇的是籠型感應(yīng)電動(dòng)機(jī)設(shè)計(jì), 其轉(zhuǎn)子的異步電動(dòng)機(jī)結(jié)構(gòu)簡(jiǎn)單、運(yùn)行可靠、重量輕、價(jià)格廉價(jià),得到了廣泛的應(yīng) 用,其主要缺點(diǎn)是調(diào)速困難.三相感應(yīng)電動(dòng)機(jī)作電動(dòng)機(jī)運(yùn)行時(shí),轉(zhuǎn)子的轉(zhuǎn)速低于旋轉(zhuǎn)磁場(chǎng)的轉(zhuǎn)速,轉(zhuǎn)子繞 組因與磁場(chǎng)間存在著相對(duì)運(yùn)動(dòng)而感生電動(dòng)勢(shì)和電流,并與磁場(chǎng)相互作用產(chǎn)生電磁轉(zhuǎn)矩,實(shí)現(xiàn)能量變換.

6、電磁設(shè)計(jì)主要的內(nèi)容是確定電機(jī)的電磁負(fù)荷及定子兩套繞 組的極對(duì)數(shù).仿真設(shè)計(jì)時(shí)需注意以下幾點(diǎn)：(1)負(fù)載的性質(zhì)明確負(fù)載需要恒功率調(diào)速或恒轉(zhuǎn)矩調(diào)速,或在整個(gè)調(diào)速范圍內(nèi)局部轉(zhuǎn)速區(qū)為恒 功率、局部轉(zhuǎn)速區(qū)為恒轉(zhuǎn)矩.(2)調(diào)速范圍確定電機(jī)的常用轉(zhuǎn)速區(qū)間和最大轉(zhuǎn)速區(qū)間,以便選擇適宜的電機(jī)數(shù)據(jù)(3)通風(fēng)冷卻系統(tǒng)在設(shè)計(jì)時(shí)應(yīng)兼顧電機(jī)各方面性能的要求, 根據(jù)不同的情況采取不同的方法,整個(gè) 電磁計(jì)算中的幾個(gè)主要局部包括：主要尺寸與氣隙確實(shí)定；定轉(zhuǎn)子繞組與沖片設(shè) 計(jì)；工作性能的計(jì)算；起動(dòng)性能的計(jì)算等.五仿真設(shè)計(jì)雙擊桌面的Maxwell 16.0 ,運(yùn)行Maxwell軟件,進(jìn)入如下界面,點(diǎn)擊菜單 文案大全實(shí)用標(biāo)準(zhǔn)欄中的,新
