摘要

SUMMARY >Mass productions of the motor core such as the blanking of the electromagnetic steel sheet and the shrink fit cause the residual strain in the material, processing strain, which prevents the movement of magnetic walls and increases the magnetic loss in the motor. Conventionally, the increase of the magnetic loss by the processing stress was evaluated with trial products, because it could not be done in the design phase. Particularly, the residual stress generated by processing has a complicated relationship with the direction of the magnetization vector, which has made it difficult to estimate iron loss considering processing strain. So, this paper clarified the relationship between the stress tensor and the magnetization vector, and proposed a consideration method of the stress in magnetic field analysis. As a result of validating the development method with the ring test piece, we confirmed that the intended modeling can be reproduced. Furthermore, we showed the usefulness of the development method in the motor model. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>摘要</ title> >大规模生产电动机芯如电磁钢板的消隐和收缩拟合，导致材料中的残余应变，加工应变，这防止了磁壁的运动并增加了电动机中的磁力损失。传统上，通过试验产品评估了通过试验的加工应力的磁性损失的增加，因为它无法在设计阶段进行。特别地，通过处理产生的残余应力具有与磁化载体的方向的复杂关系，这使得难以考虑加工应变的铁损。因此，本文阐明了应力张量和磁化矢量之间的关系，并提出了磁场分析中应力的考虑方法。由于使用环试件验证开发方法，我们证实可以再现预期的建模。此外，我们展示了电机模型中的开发方法的有用性。</ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" > 著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-22399/'>《Electrical engineering in Japan 》</a> <b style="margin: 0 2px;">|</b><span>2018年第1期</span><b style="margin: 0 2px;">|</b> <span>共11页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=DOI SATOSHI&option=202" target="_blank" rel="nofollow">DOI SATOSHI;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=AOKI TETSUYA&option=202" target="_blank" rel="nofollow">AOKI TETSUYA;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=OKAZAKI KEIICHI&option=202" target="_blank" rel="nofollow">OKAZAKI KEIICHI;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=TAKAHASHI YASUHITO&option=202" target="_blank" rel="nofollow">TAKAHASHI YASUHITO;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=FUJIWARA KOJI&option=202" target="_blank" rel="nofollow">FUJIWARA KOJI;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Denso CorporationJapan;</p> <p>Denso CorporationJapan;</p> <p>Denso CorporationJapan;</p> <p>Doshisha UniversityJapan;</p> <p>Doshisha UniversityJapan;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li> <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span> <a href="https://www.zhangqiaokeyan.com/clc/1782.html" title="输配电工程、电力网及电力系统">输配电工程、电力网及电力系统 ;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=iron loss&option=203" rel="nofollow">iron loss;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=residual stress&option=203" rel="nofollow">residual stress;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=magnetic anisotropy&option=203" rel="nofollow">magnetic anisotropy;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=electric steel sheet&option=203" rel="nofollow">electric steel sheet;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=motor&option=203" rel="nofollow">motor;</a> </p> <div class="translation"> 机译：铁损;残留应力;磁各向异性;电钢板;电机;
