Dear Karesz,
thanks for all your ideas. I think I will take the optical indexing into account also.
It is not very easy to do, but it lets me use DC motors, which are more powerful and cheaper!
What do you think? Why AC better than DC motors?
Kind regards,
Diego
Thanks a lot Elmuhamady!
I will have a look at your link (no I can not) Any idea about the model of the stepper motor? I need 6 motors and I have no six copier machine to break close to me :P
Kind regards!
Dear ScOe, thanks a lot for your reply. And thanks to everybody, I din not expected so much atention!
Let me explain you all the project. Instead of an arrow, there will be a capital letter attached to each motor. Letters must sping fast enough so they can not be distinguish. There will be...
Dear bosparra,
Thanks a lot for your information! You all are being really helpful!
Any recomendation on what a motor to buy or where to look for it?
Kind regards,
Dieg
Dear Elmuhamady,
Thanks a lot for your reply. Yes, I think that will work properly. Now I have a doubt. I will be movin an "arrow" that will weight around 2kg, and I would like to reach sucha spin speed I could not distinguish the arrow. Do you know any powerful step motor not very expensive...
Dear Karesz,
Kind regards for your reply.
Let me explain you want I mean. Imagine there is an arrow attached to the motor of the fan. Before it starts spinning it points to a direction, for example, 12 o'clock.
Then it starts spinning and spins for sometime. Then you stop it. The arrow will keep...
Hello and thanks in advance for your answers!
Please, excuse my English as it is not my mother tongue and I may make some mistakes.
Let me ask you for some help: I am looking for a system like a fan that starts and stops at the very same points. Image a stopped fan that starts spinning. When I...
Re: what is metamaterial?
Meta comes froom Geek, well said, but I dont like this definition you gave "not exactly a material"
Meta means something about that something. For example, metalanguage means language about language, like html tags and so
In this case, the best definition I can think...
meaderline
Hello everybody and thanks in advance for reading this.
I am trying to simulate a Meader-line polarizer, but I'm facing several problems. Due to the nature of the structure (very thing lines in a meander-configuration) using CST means loads of cells for an accurate simulation. I'm...
Hi everyone!
My question is pretty short and easy, i think
I have been searching on th einternet but I have not found and answer...
Can somebody tellme what the difference (or ads/cons) do ServicePack1 and ServicePack2 make compared to the simple CST MWS 5.0.0?
Thanks in advance!
Hello!
I'm trying to simulate a Biconical antenna in CST, but I having problems. It should be feed usind a coaxial cable thrugh the cones.
Does anyone have some kind of advice for this simulation or any model that have good agreement with measures?
I have tried a subgrid-meshing to get enough...

Hello,
I have to design an Alford Loop antenna and I can not find information about design. Even theoretical information is not very easy to get. Does anyone have some information that may share?
Thanks a lot.
