Choosing the best motor for my simulator 2DOF

I´m searching for the best simulator engine.
My idea is to build a 2DOF simulator with AVR Motion Controller v1.5 Dual Simple Mosfet h-bridge v1.2b designed by Thanos.
The 2 boards work, and I have built the simulator, a photo here:



I can't find any big and cheap wiper motors because in my country they are very expensive.
I found some motors of 120W, but I have some doubts whether they is going to work or not in
the simulator. Here are the specs:

Voltage: 12Vcc
Current: 14A
Revolution: 3,200rpm
Output: 120W
Torque: 3.66kg/cm
and here's the link:

http://twt.manufacturer.globalsourc...or/1001681587/Small-DC-Motor-Geared-Motor.htm

The engine model is the 10SGN-F

The reductor model is the 5GN75K

The engines are vented, unvented can be 10SGN of 65 W and 1800RPM

The reduction is of 1:75 and gives me a speed of 43 RPM
5GB75K reduction is with straight clogs and not as the wipers.
Does this cause any problem?

Are the 14a consumed a problem for the H bridge?

What is your opinion about these engines and reductions?

Thank you very much!

Sorry, I do not understand, I'm using Google Translator, you got these engines in your simulator or plan to buy now?

Hola Martín, yo tengo mi simulador armado con motores de VW Gol, y me funcionan muy bien, lo probó un amigo que pesa cerca de 100 kg y va bien, el simu de Hernán tambien tiene estos motores y funciona excelente, los podés conseguir en un desarmadero muy baratos algo asi como $ 250 el par ($ argentinos)
Cualquier duda decime

Saludos

Hi Martin, I have my simulator armed with wipermotors VW Gol, and I work very well, he proved a friend who weighs about 100 kg and goes well, the simulation of Nano also has these engines and it works excellent, you can get a junkyard very cheap something like $ 250 a pair ($ Argentines)
Any doubt tell me

Regards

Ya me recorrí los desarmaderos y lo mas barato que conseguí son $400 por uno solo, y encima era de los chiquitos...
Y en casas de repuestos están desde $800 también chiquitos, así que estoy buscando esta alternativa que son nuevos y tienen mas fuerza que los limpiaparabrisas.
El tema también de mi simulador es que tiene que mover toda la estructura, volante, pedalera, pantalla y parlantes.
Gracias!
Saludos

I've already went through the junkyard and the cheapest that I got was worth $400 and it
was one of the little ones.
And parts shops are worth since $800 also the little ones, so now I'm looking for this
alternative because they're new and and have more strenght than the wipers motor.
Another issue with my simulator is that it has to move the entire structure, steering
wheel, pedals, screen and speakers.
Thank you!
Regards

Yes I have two of these motors fitted to my simulator. I am currently testing and setting profiles to get them to move properly. They have good solid motion.

Ok, thanks for the tip.
I have a doubt because I chose are ventilated and yours aren't.
And the other thing is the gearbox, yours is with worm gear and the one I chose is with spur gears.
Will the engines that i chose work?

Hello Martin, yes the motors I use are not ventilated, however, they do not even get warm under use. The worm gear I am told by the supplier is very strong. I am seeing good results so far, but more testing over time will tell.
From what I can see in your photo, you are mounting the motors at the front, so they will be under less strain than where I have my motors. Mine are under the back of the seat and under more strain.
The motors that you have listed should work. Only one way to find out. Buy them and set them up.
Thanks, David.

buy ya motors over the net mate alot cheaper.

Then I'll have to try, but I'm very wrong with the engine I chose? Or it should work?

The final data are:

Engine:
120W
3200rpm
3.66kg/cm (0.36Nm)

Reducer:
Ratio: 1:75
43RPM
274.5kg/cm (26.91Nm)

variables look ok just beware the wipers have a plastic gear system and if ya load them up too much, ya just end up grinding the points of them, so really balance is the key.
Do ya have a link for the proposed motors and gearing for us to see, thanks

I see the gear supports up 100kg/cm of torque while the engine is 274.5kg/cm.
I would not use all the torque which has the engine, better I buy a 65W motor with these specifications:

Voltage: 12V
Current: 9A
Revolution: 1,800 rpm
Output: 65W
Torque: 3.5kg/cm

And because of the engine RPM, would have to use a 1:36 gear ratio to go down to 50RPM. The 5GN36K.
And so get 126kg/cm, which I think are sufficient.

Do you think about it?
