hen designing an electrical machinery , yet what in it takes chiefly together with resolves the action is the main dimensions of electrical machinery .The main dimensions is fixd queen , Else dimensions also may be fixd on the whole .Electrical machinery work property and the operation dependability also wholly possess the intimate relationship with main dimensions along with their ratio . By means of the electric current coil in , Electrical machinery significant part is living 、 Stimulate magic field in butt and the part of spare parts .For the sake of simplification physics image and electromagism calculation , Partly give priority to that the magic field reaches by mistake magic field in the electrical machinery to .The magic route calculation aim rests with certainly es into being the bureau in primary magic field have to magization force , Advance side by side but calculation excitationelectric current along with electricalmachinery idling performance . Resistance、 The reactance is the significant parameter of electrical machinery .The size of resistance not merely affects the electrical machinery economy , Moreover operational performance against the electrical machinery too possess the exceedingly intimate coil reactance size too possess the very great effect to design economy and operational performance .Hence it is the most significant correctly to fix calculation these parameters . He main dimensions is living 、 After air gap along with fix rotor winding and the core is designed to be in good health , Will do performance calculation and starts performance chiefly is starting torque and the minimum running current multiple to the relevant nominal value that threephase list asynchronous electric motor of squirrel cage starts the performance .Threephase list asynchronous electric motor of squirrel cage starting characteristic the parameter resolution through the electrical machinery . Keywords Electric motor , The electromagism route parameter , Work performance , Start performance 攀枝花學(xué)院??飘厴I(yè)設(shè)計 目 錄 1 目 錄 摘要 ?????????????????????????????????????Ⅰ ABSTRACT?????????????????????????????????Ⅱ 1 緒論 ???????????????????????????????????? 2 異步電機在國內(nèi)外的發(fā)展?fàn)顩r ???????????????????????? 2 異步電機在國內(nèi)的發(fā)展?fàn)顩r ????????????? ???????????? 2 異步電機在國外的發(fā)展?fàn)顩r ??????????? ?????????????? 3 3 三相單鼠籠異步電動機電磁計 算 ??????????????????????? 5 額定數(shù)據(jù)及主要尺寸 ??????????????????????????? 5 參數(shù)的選擇 ?????????????????????????????? 5 電機的主要尺寸 ???????????????????????????? 5 定子繞組的計算 ????????????????????????????8 定子槽 形的計算 ???????????????????????????? 9 轉(zhuǎn)子繞組的計算 ??????????????????????????? 10 磁路計算 ???????????????????????????????? 12 參數(shù)計算 ???????????????????????????????? 15 線圈長度的計算 ???????????????????????????1 5 電機定子繞組漏抗的計算 ???????????????????????1 6 電機轉(zhuǎn) 子繞組漏抗的計算 ??????????????????????? 18 有效材料計算 ???????????????????????????? 19 空載特性 ??????????????????????????????2 0 工作性能計算 ?????????????????????????????? 21 電負(fù)荷計算 ????????????? ??????????????? 22 電機損耗計算 ???????????????????????????? 22 主要性能計算 ????????????????????????????2 4 起動性能計算 ?????????????????????????????? 24 起動時定子參數(shù) ??????????????????????????? 25 起動時轉(zhuǎn)子參數(shù) ??????????????????????????? 26 起動參數(shù)確定 ????????????????????????????2 8 結(jié)論 ????????????????????????????????????? 29 參考文獻 ???????? ?????????????????????????? 30 致謝 ????????????????????????????????????? 31 攀枝花學(xué)院??飘厴I(yè)設(shè)計 目 錄 2 攀枝花學(xué)院專科畢業(yè)設(shè)計 1 緒 論 1 1 緒 論 隨著四個現(xiàn)代化的發(fā)展,工業(yè)生產(chǎn)的自動化程度提高,還需要大量各種各樣具有高性能的控制電機作為自動化系統(tǒng)的控制元件或執(zhí)行元件。 隨著 CAD/CAM 等軟件進行計算機輔助設(shè)計、輔助制造技術(shù)的大量應(yīng)用以及以計算機控制的柔性制造系統(tǒng)、主體倉庫 、機器人進 行裝配等的組合,由計算機控制材料、部件的供應(yīng)管理達到全廠高效率、高質(zhì)量的全自動化均衡生產(chǎn)的實現(xiàn),產(chǎn)品研發(fā)和生產(chǎn)周期大大縮短,制造成本顯著降低;電子計算機和電力電子技術(shù)的發(fā)展使小功率電機產(chǎn)品進入了一個新時期,交流變頻調(diào)速已經(jīng)逐步取代直流電機 調(diào)速,逆變器與異步電機結(jié)合一體,有標(biāo)準(zhǔn)的電機安裝尺寸、調(diào)速比 10∶ 1 的逆變器電動機已經(jīng)工業(yè)化生產(chǎn),有程序控制功能的智能電動機、開關(guān)磁阻電動機等已經(jīng)應(yīng)用于各個領(lǐng)域,顯示出顯著的技術(shù)優(yōu)勢,無刷直流電動機、盤式永磁直流電動機、薄型穩(wěn)速電動機等產(chǎn)品也以較高速度發(fā)展;再加上新型稀土磁鋼的使用,使小功率電機本機制作體積越來越小;再則電機與整體結(jié)構(gòu)一體化技術(shù)的引入進一步縮小了體積,簡化了結(jié)構(gòu),提高了系統(tǒng)精度和可靠性,集電子技術(shù)、微電子技術(shù)、傳感器技術(shù)于一體的小功率電機不僅可實現(xiàn)多功能,而且可借助計算機記憶、運算、處理功能 提高電機控制精度和靈敏度,成為智能化產(chǎn)品。 國 家已明令不再生產(chǎn) JO2 系列異步電機, “ 九五 ” 期間將生產(chǎn) Y系列、 Yx 系列及其它通用或?qū)S酶咝Ч?jié)能電動機約 kW(未包括更換現(xiàn)有 JO2型用的新型電動機 )。 攀枝花學(xué)院??飘厴I(yè)設(shè)計 3 三相單鼠籠異步電動機電磁計算 5 3 三相單鼠籠異步電動機電磁計算 額定數(shù)據(jù)及主要尺寸 參數(shù) 的 選擇 通過給出的已知參數(shù)、查找資料和對任務(wù)書的要求選定了以下的參數(shù)來作為我的三相單鼠籠異步電動機設(shè)計。齒寬計算如下: ? ?1 1 1 21 2 1122 2ioi D h hbrZ? ??? ? ? ? ?0 . 1 7 2 0 . 2 2 8 2 0 . 1 5 2 2 0 . 0 5 1 0 . 0 0 7 436 mm? ? ? ? ??? ? ? ????? ? ? ? ?1 1 1 11 1 112 2 0 . 1 7 2 0 . 2 2 8 2 0 . 0 0 1 1 0 . 0 0 7 7 0 . 0 0 7 4 736ioi D h hb b m mZ??? ? ? ? ? ???? ? ? ? ????? 齒部基本平行,齒寬 1ib?
