<p>Hi, I am trying to create a basic structure using rmxprt first and analyze the core loss of an axial flux motor using maxwell.<\/p><p>\"\"<\/p><p>The equation for three-phase AC is as follows:<\/p><p>54*sin(2*pi*50*time)<br>54*sin(2*pi*50*time-2*pi\/3)<br>54*sin(2*pi*50*time-4*pi\/3)<\/p><p>\"\"<\/p><p>And the permanent magnet’s magnetization and number of poles are automatically specified in rmxprt, <\/p><p>and the core loss coefficients are also defined, and in excitation, the set core loss is checked for the stator and rotor.<\/p><p>\"\"  \"\"<\/p><p>Looking at the picture, it looks like the 3-phase AC is properly authorized.<\/p><p>However, I’m wondering if the core loss seen in the picture is only the loss of the stator and rotor.<\/p><p>And in the setup, I think you need to check the item called “View core loss by object?” to be able to view the loss of each object, such as the stator and rotor, separately, but I don’t have that.<\/p><p>\"\"<\/p><p>And if you look at the torque graph, you can see a negative average value. <\/p><p>\"\" \"\"<\/p><p>In conclusion, how can I see the core loss graph for each object (e.g. stator, rotor)? And how can I get positive average torque instead of negative average torque?<\/p><p>Also, There is no core loss item in the calculator (Quantity), only total loss.<\/p><p>I’ve searched the manual and other places, but I just can’t find the answer.<\/p><p>”Thank you for taking the time and effort to read through my lengthy message—I truly appreciate your patience and attention to detail.”<\/p><p> <\/p><p> <\/p><\/p>\n","protected":false},"template":"","class_list":["post-396247","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["396247"],"_bbp_subscription":["485176","82626"],"_bbp_author_ip":["155.230.175.33"],"_bbp_last_reply_id":["396533"],"_bbp_last_active_id":["396533"],"_bbp_last_active_time":["2024-12-06 01:28:35"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["485176","82626"],"_btv_view_count":["630"],"_bbp_topic_status":["unanswered"]},"test":"wonseiii99gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396247","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\/396247\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=396247"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
