¿How to set correctly coils for induction cooktops?

Hi all.

I am trying to model a an induction cooktop in 2D. I want to do several simulations including differetn level of excentricty between the coil and the pot.

Here my questions.

1.- Axysimetry works for this?

2.- If I want to put 50 Amps, peak-peak to the induction coil, wich value do I need to put in the electric circuit?

3.- What is the difference between putting the coil in series or parellel?

    Hi,

    By excentricity you mean that the axis of the coil and pot are different? In this case axisymetric can not be used, 3D simuation is necessary.

    For the conversion to peak to peak to RMS, you have to divided the peak to Peak value by 2*sqrt(2)=50/(2*sqrt(2))=17.67ARMS

    For the coil serial or parrallel option is maintly used for rotating machine to defined the connection of the coil not repsented in the FE Domain in case of periodicity. We can have coil in serial or parrallel at the end it will just adpat the value of the current in the coil. If there are coil in parrellel the value of the current will be divided by the number of parallel path. This allows to defined in the current sources the real current we imposed to run our motor.

    In your case you have to used all in serial

    I hope this helps.

    Best regards.

    Hi,

    Thanks for helping with this. You're guidance really helped.

    Now I am looking for calculating inductance for the pot and for the induction coil.

    Do you have some tips for these new challenges ?

    Regards
