Does it have to do it automatically? If not, I'd start with something like this: http://www.amazon.com/150RPM-Torque-Electric-Speed-Reducing/dp/B0087Y7UGI/ref=sr_1_1?ie=UTF8&qid=1463696436&sr=8-1&keywords=24v+motor
I would spend some time getting ballpark numbers about the performance required of the motor, but I wouldn't sink a bunch of time into perfect answers. You're going to be limited by the motors you can buy, so knowing you need with with X stall torque and Y max RPM isn't going to do you much good. Pick a motor and design a reduction around it.
If you have to do it automatically, get yourself a standard hobby continuous rotation servo and an arduino.
If you need some light weight gears/chains/pulley things these guys have stuff that would probably work for you: http://www.vexrobotics.com/vexedr/products/view-all?ref=tile
Donc un moteur dans ce style fonctionnerait?
EDIT: si j'ai bien compris, oui ça fonctionnerait, rest à savoir combien de temps il mettra à ouvrir la porte. En gros, il faut que je puisse determiner le rapport entre mon petit et mon gros pignon (analogie cycliste). Si mon moteur tourne à 150 rpm, mon grand pignon tournera moins vite mais avec plus de "torque".
EDIT 2 :Je suis sur mon vélo, grand pignon petit plateau. Pour atteindre une vitesse de 15km/h sur du plat, je dois développer une énergie x. Sur une pente à 10%, pour rester à 15km/h je dois développer une énergie y avec y >x . C'est là où je me demande comment il est possible de quantifier cette énergie en fonction du poids (ou de la masse, je sais pas). J'espère que mon analogie est claire (ça l'est pas trop dans ma tête pour être honnête)
Ok that makes sense. This motor has a 1.8 deg step and using this calculator will move at approx. 8 revolutions per second, which is twice as much as the 3.6 rev/sec required for 720 steps/second. Any noticeable problems?
