What should I do 3 phase Generator 2D in Model library
Hi,
This example is the single phase Gen.
If the single phase Gen can be three phase Gen, How to improve or apply it
Vi=NN * L (integration(Ez.dA)) / A
This eq from
And the Eq can be use with three phase or not
What is the principle to definte Vi
Thanks you in advance

Re: What should I do 3 phase Generator 2D in Model library
Hi,
i'm simulating also 3 phase motor (U, V and W) and using this
ViU= mod1.intopUp(L*rmm.Ez/A)-mod1.intopUn(L*rmm.Ez/A)
mod1.intopUp ist integration of U phase wire that goes -p for positive, -n for negative
ViV=mod1.intopVp(L*rmm.Ez/A)-mod1.intopVn(L*rmm.Ez/A)
ViW=mod1.intopWp(L*rmm.Ez/A)-mod1.intopWn(L*rmm.Ez/A)
it's just worked (it solved. i havent evaluate the result, but maybe...

Hi
if you have 3 phases at 120° dephasing, you probably have a "phasor" term and should consider the real and imaginary parts, no ?

Good luck

Dear Akmal,
I am trying to simulate the 3-phase induction motor, but i do not know how to deal with the phase A, B , and C
can you help me please
Thanks

Re: What should I do 3 phase Generator 2D in Model library
Hi Akmal,
I have COMSOL 3.5, and I think the model is made on COMSOL 4.1.
I can not open it !!!!
Is there any idea ???
Also I am trying to simulate the induction machine, but the software can not mesh one part.
Can you help me how to mesh it manually ?? or any idea to overcome this problem.
you can write to me directly to my email

Daer Akmal,
I have already solved the problem of mesh
but still i do not know exactly how i should deal with phases ?!!!
I tried to inject the windings by current density J varies with time , is that correct ????
Please reply to this
