I first built a 3D model using current excitation and was able to get the expected torque, but when I try to use the same approach in the 2D linear model, the results don&rsquo;t look right. Because of that, I switched to voltage excitation, but then I got confused about what values to use for resistance and inductance&mdash;whether they should represent just the conductor or the full phase winding including end windings. I used analytically calculated phase resistance, which made the simulation more stable, but the flux linkage dropped to almost half of what I was getting in 3D, and the torque is also off. I then tried to check the no-load condition by setting slip to zero and defining the linear velocity in terms of slip, but I&rsquo;m still getting significant torque, similar to the load case, which doesn&rsquo;t make sense. I also tried using RMxprt just to cross-check, but there the phase current seems unusually high. I have worked with radial flux machines before, but this is my first time working with axial flux induction machines, so I might be missing something fundamental. I&rsquo;d really appreciate any guidance on how to properly define the excitation, choose correct resistance\/inductance values, and simulate a true no-load condition in a 2D LMMA AFIM model.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-457054","topic","type-topic","status-publish","hentry","topic-tag-induction-motor-maxwell2d","topic-tag-motor-design","topic-tag-RMxprtDesing-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["457054"],"_bbp_author_ip":["2001:6b0:2:2801:48b0:845b:d664:d3c7"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["457054"],"_bbp_last_active_time":["2026-04-24 14:13:02"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["1"],"_bbp_engagement":["679961"],"_btv_view_count":["22"],"_bbp_topic_status":["unanswered"],"_bbp_notification_enabled":["679961"]},"test":"challastudent-chalmers-se"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/457054","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/457054\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=457054"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
