三相异步电动机的电磁设计

兰州交通大学毕业设计（论文）-I-摘要Y2系列电机是在Y系列电机基础上更新设计的一般用途电机，它具有结构简单、制造、使用和维护方便，运行可靠，以及重量轻，成本低等优点，在电机噪声、振动水平优于Y系列电机，外观更加满足国内外的用户需求，本文为Y2-112M-2的电磁设计。在设计过程中，掌握了中小型三相感应电机的设计原理，熟悉相关的技术条件，基于给定的参数结合相关的技术条件，确定与电机的电磁性能有关的尺寸，选择定、转子的槽数和槽配合，确定槽型尺寸，选定有关材料，编程进行电磁计算，结合前面的数据计算出相应的工作性能和起动性能，包括效率、功率因数、最大转矩倍数、起动转矩倍数、起动电流倍数等。为了减小误差和计算量，还在MATLAB中编写了电磁计算程序。此外，本设计还用CAD绘制了定、转子冲片图以及定子绕组分布图,最终使技术指标符合任务书的要求。通过对电机性能尺寸的确定，以及对槽型的选取，选定了有关尺寸，通过编程的反复调试，使其技术指标符合任务书的要求，最终设计出符合任务书要求的电机。关键词：Y2-112M-2三相异步电动机;定、转子；电磁设计计算兰州交通大学毕业设计（论文）-II-AbstractY2seriesmotorsisdesignedonthebasisofYseriesmotorupdategeneralpurposemotor.ithasasimplestructure,convenientmanufacture,useandmaintenance,reliableoperation.aswellaslightweight,lowcostadvantages,themotornoiseandvibrationlevelisbetterthanthatofYseriesmotor.appearancemoremeettheneedsofusersathomeandabroad,thispaperdesignedforelectromagneticY2-112m-2.Intheprocessofdesign,masterthedesignprinciplesofsmallandmedium-sizedthree-phaseinductionmotor,familiarwithrelevanttechnicalconditions,basedonthegivenparameterscombiningwithrelatedtechnicalconditions,determinethesizeoftheassociatedwiththeelectromagneticperformanceofthemotor,\option,rotorslotnumberandgroove,groovetypesize,selectedmaterialsprogrammingelectromagneticcalculation,Finally,combinedwiththepreviousdatatocalculatetheworkingperformanceandthecorrespondingstartingperformance,includingefficiency,powerfactor,themaximumtorque,startingtorque,startingcurrentratioetc.Inordertoreducetheerrorandtheamountofcalculation,preparedelectromagneticcalculationprograminMATLAB.Inaddition,thedesignalsodrawing,therotorandthestator,windingsdistributionprintswithCAD.thetechnicalindicatorsinlinewiththerequirementsofspecification.Todeterminethesizeofthemotorperformance,aswellastothetroughtypeselection,theselectedsize,bytherepeateddebugprogramming,makethetechnicalindicatorsmeettherequirementsofthespecification,thefinaldesignconformtotherequirementsofthespecificationofthemotor.KeyWords:Y2-112M-2three-phaseasynchronousmotor,thestator,therotorElectromagneticdesigncalculation兰州交通大学毕业设计（论文）-III-目录摘要.....................................................................................................................................IAbstract......................................................................................................................................II目录..................................................................................................................................III1绪论......................................................................................................................................11.1工程背景...................................................................................................................11.2设计范围...................................................................................................................11.3设计依据...................................................................................................................11.4设计目标...................................................................................................................11.5本文的主要工作.......................................................................................................12三相异步电动机主要参数的确定......................................................................................22.1主要尺寸及气隙长度的确定...................................................................................22.2定、转子槽形及槽配合的确定...............................................................................22.2.1定、转子槽形的选择....................................................................................22.2.2定、转子槽形尺寸的确定..........................................................................32.2.3槽配合的选取................................................................................................32.3绕组型式及节距的选择...........................................................................................32.3.1绕组型式的选择............................................................................................32.3.2绕组节距的选择............................................................................................32.4计算概述.....................................................................................................................42.4.1磁路计算..........................................................................................................42.4.2参数计算..........................................................................................................43电磁计算..............................................................................................................................43.1额定数据及主要尺寸.................................................................................................43.2磁路计算.....................................................................................................................63.3参数计算.....................................................................................................................93.4工作性能计算.....................................
