The issue arises with the stator material: when I assign M19-24G, it produces torque close to the expected value. However, when I switch to a material like Cogent Power M330, which has a higher saturation flux density and permeability than M19, the torque drops by about 15%. Interestingly, when I select a superior material (containing cobalt) with significantly higher saturation flux density and permeability, the torque returns to the expected value.&lt;\/p&gt;&lt;p&gt;I&#8217;ve experimented with various mesh sizes, boundaries, and regions, but the results consistently show the same pattern. Even when I keep everything identical in the design and only change the B-H curve (which I have verified and tested with multiple grades), the issue persists. I&#8217;m honestly quite confused at this point, and I would really appreciate any suggestions you may have.&lt;\/p&gt;&lt;p&gt;Thank you!&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/09-09-2024-1725872179-M19.jpg\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/09-09-2024-1725872198-Cogent.jpg\" alt=\"\" \/>&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-381912","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello everyone,I&#039;m currently simulating an electric motor and generating a Torque vs. Time graph (Transient Simulation).
