TAGGED: inductance, maxwell, rmxprt

My name is Kepa and I am a r&d electrical engineer in Ingeteam and also an Ansys Maxwell user. The reason why I am writing to you is because we are having problems with the difference between the results we obtain using RMX or using Maxwell.
We want to obtain the value of the induction on the airgap of an Asynchronous Electric machine, on the one hand, in the simulation performed using RMX we are able to obtain the value of the induction on the airgap searching for it on the solution data file on the RMX results as you can see on the image below.February 2, 2022 at 2:59 pmDeyu LiAnsys EmployeeRMxprt is an analytical tool, while Maxwell is a FEA tool. Analytical technique is fast and powerful under certain conditions, but FEA has been proven to be very robust for general electromagnetic analysis.
February 2, 2022 at 3:24 pmKIB_irdeSubscriberthanks for your answer, I know that booth tools have different calculation methods, but the difference we obtained using each tool is too big for our perception, the results we have obtained using RMX are similar for the ones we have calculated analytically, but Maxwell is suposed to be a better tool for inductance calculations, so I think that I am doing something on the wrong way with the simulation on Maxwell. I supose that it is not usual to obtein such different results.
February 8, 2022 at 10:22 amKIB_irdeSubscriberHi again,here I come again. Have yo got any idea of why I am obtaining different results with RMX and Maxwell2D? Is it usual to obtain this differences between both simulation tools?
February 9, 2022 at 3:43 pmDeyu LiAnsys Employeeglad to hear RMxprt matches your calculation analytically. Yes, there is an expected difference between Maxwell result and RMxprt result, because those two tools are using different techniques.
