Ansys Maxwell Modeling of Switched Reluctance Motors

Click For Summary
SUMMARY

The discussion focuses on optimizing design parameters of Switched Reluctance Motors (SRM) using Ansys Maxwell's Optimetrics feature in conjunction with a Genetic Algorithm (GA). The user seeks guidance on how to parameterize design elements such as the outer and inner diameters of the stator and rotor. Challenges with GA convergence in Optimetrics are highlighted, indicating potential issues in parameterization or setup. The conversation suggests consulting Ansys representatives for specific troubleshooting and optimization strategies.

Hi Everyone
i'm new member of Physics Forums, my research field is about Switched Reluctance Motors
i have question about Optimetrics in Maxwell!
my question is:
How can Optimize Design Parameters ( like Outer and inner Diameter of Stator and Rotor or Embrace of them) of a Switched Reluctance Motor in Optimetrics with a GA Algorithm?
i design a SRM with analytical Formula, and now i want optimize my design in Optimetrics!
Please Guide me about parts of this Option (Optimiation) of Maxwell
Regards.

I think if you can parameterise it, you can change it with optimetrics. For example you would give your rotor diameter a variable name during building the model, then any dimensions that are dependent on that would have equations, eg if you make it depend on rotor diameter, then stator ID would be "rotor_diameter+air_gap" etc.

I'm not sure on the specifics of exactly how you would do this, but I'd just ask your Ansys rep, they are usually more than helpful with such things.
 
ok , its true, but i have a problem with Convergance of GA Algorythms , my Optimetric doesn't converge! i parameterise SRM design parameters and specify condition but GA doesn't Converge! what is the problem of my work? Do you have example about this to send me?

Do you still need examples or even do you still work with maxwell?
 
The OP has not been here since November 2018, so this thread is locked.
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
