Noise due to electro magnetic forces i an motor

Maybe this topic can help you.

Also OptiStruct user guide has some more info.

Hello Adriano,

I am currently working on this simulation and facing an issue. Can you help me?

Hello Adriano,

Hello Rajesh,

Is your issue in Flux or Optistruct?

Thank you,

Lavanya

Hello Lavanya,

Actually it is dependent. I ran a ERP in optistruct and am getting the below result.

In order to understand the the above curve, I have to understand the output curve(radial and tangential force). Can you help in reading the below curve? what is x axis and y axis mean? 

Thanks & Regards

From the EM point of view this is the plot of the force on one node in frequency that you can generate in the mechanical context in a constant speed working point computation.
As discussed yesterday, the frequency mainly depends on the speed (if we referring at the same motor).
