Ansoft Maxwell 3d Closely coupled inductor

Click For Summary

Discussion Overview

The discussion revolves around issues related to simulating a closely coupled inductor using Ansoft Maxwell 3D. Participants are exploring the challenges of obtaining graphs for inductance and induced voltage in a specific circuit configuration involving two coils and a movable core.

Discussion Character

  • Technical explanation, Experimental/applied, Debate/contested

Main Points Raised

  • One participant describes a circuit with a 28Vac source at 400Hz and two coils, each with a resistance of 18.6 ohms, connected to a common point.
  • The participant mentions that the core's position affects the induced voltage and inductance, citing hand calculations that suggest inductance values of 100mH and 50mH under different core positions.
  • Several participants express difficulties accessing shared simulation files, indicating potential technical issues with the links provided.
  • There is a sense of frustration regarding the lack of engagement on the topic, as one participant notes that it seems to be an uninteresting subject for others.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the technical issues presented, and there are competing views regarding the accessibility of the shared files. The discussion remains unresolved regarding the simulation challenges.

Contextual Notes

Limitations include potential issues with file sharing and access, which may hinder collaborative troubleshooting. The discussion does not clarify the assumptions behind the inductance calculations or the specifics of the simulation setup.

Hello! I am having an issue with getting any graphs on inductance or induced voltage.

In the attached circuit:
What I have is a 28Vac source w/ 400hz and 2 coils (R=18.6ohm each) that are connected with a common.

In the model:

I have a core in the center that will be able to move up changing the induced voltage and inductance when taken from the input of coil 1 and common or input of coil 2 and common. I know from experience (and hand calculations), that the coil will have 100mH from top to bottom when taken from input of coil 2 and output of coil 1 and with 50mH on each when the core is centered (obviously).

Any help will be appreciated,
(wrote this fast, sorry if it's hard to understand)

Thanks

Guess this wasn't a fun topic for anyone
 
neither of your links will open
 
Really? They work when I tried them
 
i get an advertisement at filehosting
and no recognition of a file by the name in your other link

windows 7, ie9

maybe somebody else can help
