Issues with Salient Pole SM Model

Hello Everyone.

I hope you are doing well.

WFSM_GEO_MESH.FLU.zip

I used Overlay to get geometry for SPSM with damper barsand then updated the geometry to split the slot into 4 equal sections for a double winding setup. The issue I'm having is that my voltage is not sinusoidal, and the stator coils have very high current.

I noticed that during physics creation, I was getting the message " Warning: the field ' Transient Magnet ' is not set. Check carefully its value before validating the box. "What does it mean, and could it be the issue?

I did my best to get this model running, starting from scratch and building my learning curve with Flux. Any help would be appreciated. The attached project does not have a mesh.

Hi Qaza,

This is warning message(not an error) and will not stop from solving the model. You can proceed for solving. I tried but didnot reproduced it.

In future cases, i would like you to raise a support case instead of forum since you are working on a specific project.

Thanks

Karun,

Thanks for your comment, yes I can solve the project, I will troubleshoot the model to get the correct voltage/ current waves

Thanks

Hi Qaza,

Thank you for contacting Altair Forum.

The warning is due to not defining the application. Please define the application transient Magnetic from the Menu bars of Flux software. Applications»Define»Magnetic »Transient magnetic» with stacklength(_OS_SL, parameter) of your machine. And then continue with your physics assignment like materials, motion, circuit etc..

Thanks

Karun,

Thanks for your prompt reply.

I shared the project before defining the application on purpose in case it would help with troubleshooting.

So what I did is as follows: define the application as Transient with __OS_SL as the depth of the domain, define mechanical sets for the Rotor and Stator, and then define a new material. Once I clicked "okay," the warning message came again. Next, I tried to delete the material and create it again, this time without a warning message, as in the output log below.

I also noticed this with the mechanical set. The first time I modified physics, I got this warning, delete and create again no warning.

It's really strange because I'm defining an open circuit, and the stator coils have current. Not sure if this warning has anything to do with coil currents.

Thanks in advance for your help.
