Hello,

I am simulating a brushed DC motor employing Ansys Maxwell software, i want to obtain the ripple current of this motor. 

The ripple current i measure in real life is just the current measured in one of the wires that connects the motor and alimentation it looks like this (the yellow one)

 

Performing the simulation, the software plots the Torque ripple but it is not the current ripple

So, anyone knows how to obtain the plot of the current from the wire that 'connects' the motor with alimentation?

 

Thanks :)

Hi ,

Could you share a picture of your Maxwell model? I don't think you can get the same glitch as your measurement but the winding current should be available in the trainsient rectangular reports>>winding>>winding current.

Hello, this is the model

 

In tansient rectangular reports i find Winding>>Current(Coil0) but it does not match the waveform of the measurement (it takes negative values)
