<\/p>\nI am currently working to perform a co-simulation between ANSYS Maxwell 2D and Twin Builder (formerly Simplorer). However, I have encountered an issue that I have been unable to resolve.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
My workflow is as follows:<\/p>\n
On the Twin Builder side, my system consists of:<\/p>\n
The three motor phases (PhaseA, PhaseB, and PhaseC) are connected correctly to the FEA component. For the mechanical side, I connected the MotionSetup ports using a torque meter, speed meter, inertia, and mechanical ground, following the ANSYS examples as closely as possible.<\/p>\n
However, during co-simulation:<\/p>\n
It is important to note that the exact same Maxwell model works correctly when simulated independently, so the motor model itself appears to be valid.<\/p>\n
Additionally, I sometimes receive the following error message:<\/p>\n
FEA1: failed to find Norton equivalent\n(check for voltage sources directly connected to windings)<\/code><\/pre>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n <\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nThis error does not always occur. Sometimes the simulation starts without this error, but the rotor still does not rotate and the speed remains zero.<\/p>\n
I also found a similar discussion on the ANSYS forum regarding MotionSetup connections. I tried implementing the suggested mechanical configuration, but unfortunately the behavior did not change.<\/p>\n
I would greatly appreciate your guidance on the following questions:<\/p>\n
\n- What is the correct way to connect the MotionSetup1_in and MotionSetup1_out ports when using Maxwell 2D with Twin Builder co-simulation?<\/li>\n
- For a BLDC\/PMSM motor operating under no-load conditions, what mechanical components should be connected to the MotionSetup ports?<\/li>\n
- Why would a motor that runs correctly in Maxwell fail to rotate when connected through the FEA Link in Twin Builder?<\/li>\n
- What is the root cause of the “failed to find Norton equivalent” error, and how can it be resolved?<\/li>\n
- Are there any known export settings, FEA Link configurations, or Twin Builder requirements that could cause this behavior?<\/li>\n<\/ol>\n","protected":false},"template":"","class_list":["post-463443","topic","type-topic","status-publish","hentry","topic-tag-AnsysMaxwellelectronics-1","topic-tag-simulation-2","topic-tag-ansys-simplorer","topic-tag-ansys-twin-builder","topic-tag-bldc-motor","topic-tag-co-simulation","topic-tag-co-simulation-of-simulink-and-maxwell-1","topic-tag-electric-drive-2","topic-tag-electric-motor-1","topic-tag-inverter-2","topic-tag-simplorermaxwell2D-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
