Air gap flux densities for a single node/point of a motor

Hi,

I have a ‚How to‘ question in flux regarding motor simulation

Is it possible to get the air gap flux densities for a single node (along air gap path like the EM forces in data import/export context) for a 90° rotation (for ex. From 45°-139°) using Altair flux?

I looked it up in help section and I could not find a straight forward way.

One of the solution was to create a path along air gap and a plot can be generated for this path for a selected angular position of rotor. But then I had to change the angular position of rotor manually to get the flux densities, for the selected node in subsequent steps

Is there a better way to plot the tangential and radial air-gap flux density (like the tangential and forces)!

 

Regards

    Hello Divin,

    The magnetic flux density is a quantity you can visualize and export from the standard Flux context.

    The best way to export this quantity from the same nodes is to create a path with points coincident with nodes of interest. To do that you can create an arithmetic mesh line to assign at he sliding line and choose the right number of points to have along the path.

    When you create a path you can choose the mechanical set to associate to the path as in the picture below. From this choice depends then the position during the solving steps; so if you want to have the path in the same position you have to choose the mechanical set fixed.

    I hope this can help you. 

    Best regards,
