(EXPLOSION-PROOFELECTRICMACHINE)2023年第2期第58卷(总第231期)定子辅助齿尺寸对永磁牵引电机齿槽转矩的影响研究王冬梅(中车株洲电机有限公司,湖南株洲412001)摘要以一台36槽30极大功率永磁牵引电机为例,采用有限元法,建立了电机二维电磁场模型,计算了辅助齿宽度和高度变化后永磁牵引电机齿槽转矩的变化趋势。结果表明,增加辅助齿后可以降低齿槽转矩的大小,选择合适的辅助齿宽度和高度尺寸可以显著降低齿槽转矩。关键词永磁牵引电机;齿槽转矩;辅助齿DOI:10.3969/J.ISSN.1008-7281.2023.02.11中图分类号:TM301.3文献标识码:A文章编号:1008-7281(2023)02^0041冶04InfluenceResearchofStatorAuxiliaryTeethDimensionsonCoggingTorqueofPermanentMagentTractionMotorsWangDongmei(CRRCZhuzhouElectricMachineCo.,Ltd.,Zhuzhou412001,China)AbstractTakinga36-slot30-poleextra-highpowerpermanentmagnettractionmotorasanexample,thispaperestablishesa2Delectromagneticfieldmodelofthemotorbyfinite-ele?mentmethod,andcalculatesthevariationtrendofthecoggingtorqueofthemotorafterthechangeofauxiliarytoothwidthandheight.Theresultshowsthataddingtheauxiliaryteethcanreducethecoggingtorque,andselectingappropriatewidthandheight...
