中国电工网www.chinaet.net基于软磁复合材料的轴向磁通永磁电机的铁耗分析*平佳齐,张志锋,武岳(沈阳工业大学电气工程学院,辽宁沈阳110870)摘要:无磁轭分块轴向磁通永磁电机具有体积小、径长比高、功率密度高、转矩密度大、铁心材料用量少、铁心磁路短等优点,尤其是应用于空间小的场合时,其技术优势更加明显。但随着电机频率的增大,电机铁耗也不断上升。为了降低电机铁耗,可选用软磁复合材料(SMC)取代传统硅钢片。与传统硅钢片相比,SMC具有涡流损耗低、易于成型等特点。将轴向磁通电机的定转子铁心分别选用SMC材料与硅钢片材料,通过仿真对比转矩和铁耗,并考虑不同频率的影响,验证了在高频率下SMC电机具有更为显著的低铁耗优势。关键词:软磁复合材料;轴向磁通电机;铁耗;硅钢片中图分类号:TM351DOI:10.19768/j.cnki.dgjs.2023.01.002IronLossAnalysisofAxialFluxPermanentMagnetMotorBasedonSoftMagneticCompositeMaterial*PINGJiaqi,ZHANGZhifeng,WUYue(SchoolofElectricalEngineering,ShenyangUniversityofTechnology,Shenyang110870,China)Abstract:Thenon-yokesegmentedaxialfluxpermanentmagnetmotorhasthecharacteristicsofsmallvolume,highdiam-etertolengthratio,highpowerdensity,hightorquedensity,lesscorematerialconsumptionandshortcoremagneticcir-cuit,etc.Especiallywhenitisusedinsmallspace,itstechnicaladvantagesaremoreobvious.However,withtheincreaseofmotorfrequency,theironlossofmotorisalsorising.Inordertoreducetheironlossofthemotor,softmagneticcom-posite(SMC)ca...
