2、要求學(xué)生在設(shè)計(jì)過(guò)程中能正確查閱有關(guān)資料、圖表及公式。 題目2: 丫132M6 額定數(shù)據(jù)與性能指標(biāo)1、電機(jī)型號(hào) Y132M6 2 、額定功率 P N=5.5kW3、額定頻率fN =50Hz 4 、額定電壓及接法UN=380伏1- 5、極數(shù)2 p=66、絕緣等級(jí)B7. 力能指標(biāo)：效率n = 0.8538 、功率因數(shù)COS甲=0.789、最大轉(zhuǎn)矩倍數(shù)TM = 2.0起動(dòng)性能：起動(dòng)電流倍數(shù)I； = 6.5,起動(dòng)轉(zhuǎn)矩倍數(shù)Ts； = 2.0D 1= 0 .21 m主要尺寸 DH = o.148m| = 0.18m 二 0.35mm Di2 = d 二 0.048 m轉(zhuǎn)子外徑 D2 二 D - 2 二 0.

3、1473 m定子槽形采用斜肩圓底梨形槽：b01 = 3.5mm, h01 = 0.8mm; bs1 = 6.8mm,30 , rs1 = 4.4mm, hs11 hs12 = 11.5mm轉(zhuǎn)子采用斜肩平底槽：b02 二 1mm , h02 二 1mm ; bs21 = 6.5mm, bs22 二 2.6mm, ： 2 = 30 , hs21 hs22 二 20 mm三概述三相異步電機(jī)廣泛應(yīng)用于采礦、機(jī)械、冶金、油田等領(lǐng)域。三相異步電機(jī)在 工業(yè)中起著重要的作用。與其他機(jī)器相比，它具有成本低、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)，比如小的起動(dòng)轉(zhuǎn)矩，表現(xiàn)不佳的速度控制在輕載和低 功率因數(shù)。A

4、n soft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)化前期項(xiàng)目的設(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?？勺詣?dòng)加載幾何和自動(dòng)定義的各個(gè)部分材料，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An soft Maxwell進(jìn)行建模。詳細(xì)分 析步驟和過(guò)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An soft Maxwell 14中進(jìn)行仿真和計(jì)算，來(lái)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(guò)一系列的計(jì)算，為后續(xù)進(jìn)行仿真設(shè)計(jì)打下了基

5、礎(chǔ)， 三相異步電動(dòng)機(jī)電機(jī)設(shè)計(jì)是個(gè)復(fù)雜的過(guò)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)格便宜，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。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

6、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)部分轉(zhuǎn)速區(qū)為恒 功率、部分轉(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，以便選擇合適的電機(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)主要部分包括：主要尺寸與氣隙的確定；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)擊菜單欄中PrmpeftE 冷qedJ1 RMMlOewqnl - MdcJne廠 Stn hl44u的，新建電機(jī)設(shè)計(jì)ITBA I h IPUI-I !
