need help with motor and controller

[ashb82]

this is what i have maybe someone can help me. i have no idea about motors or electronics so i need help with a project i am working on.
i am tring to control a Variable geometry turbocharger on a car . here is how it works Holset VGT
. i would like to know what i would need to have to control this. i have a software i use to tune my car that can send 0 to 12 volt signals . what i am wanting to do is be able to turn this thing 0deg at 0v then say 45deg at 6v, 90deg at say 12v then have it go back to 0deg at 0v.

Hi,

Only glad I didn't break out the popcorn to watch this movie, man, it's blacker than a French movie and just as informative

What kind of inputs does your cream whipper need?
Got any datasheets on the thing?
(We're engineers, not mind readers)


Btw. The software used for tuneups won't do any good here.

i know nothing about electric motors but i bet i can learn. What i would like to do is move that gear the guy works with his hands in the video. i would have to work it with my tuning software. the reason my software would have to work this is as my RPM's increase i need to turn the part the guy turns with his hands. i just dont know the terms you guys use for stuff.  there has to be a simple electric motor, stepper motor, servo some thing that you can program that will turn in degree. i will give you a example the best way i can explain it you have to understand i know very little about this kind of stuff

ok if i take a 12v electric motor and hook up 6 volts it will turn very slow if i put 12 volt on it the motor will turn faster. i would like to have a electric motor or something equal that when i hook 6 volts up to it will turn what ever degree i want  then stop is this even posible. i know this can be done the throttle on cars work like this now. when you press on the gas pedal on your car it sends a signal to your throttle to open x amount

maybe this will help http://en.wikipedia.org/wiki/Electronic_throttle_control

Hi,

Anything can be done if you've got the grit, but your video is still only showng a black screen - not much info in that.

the screen shows a spinny black wheel...

Hi,

Ah, I got it directly from YouTube now. Didn't spin, just show a "lifting" wheel and its "lever".

Either use a pro grade servo or make one yourself.

We still need some basics on the setup, like how hard is it to turn the thing (the "lever"-wheel and how is t going to be interfaced - are you up to the mechanical side of it?
What kind of speed is needed for a 0° to 90° swing?
What kind of resolution is needed?
What is the max. temperatures it will see?
What kind of signal are available to use for the positioning?

this thing has a servo motor and controller somthing maybe you guys know what it is. i just dont know how to make it move. it has 4 wires coming out of it.here are all the pics and info i can get from it

here is the one i have
