Question Motors

Hi All,
I've been pondering a set up for a long time and starting building one in the past with components bought from a website in France (that I'm sure everyone knows) that unfortunately has now disappeared; at least for UK folk. Anyway, I am looking at Motors and which to go for and was looking at ones on eBay that go by this title "Pair of Worm Gear 24v 400w 120rpm Motor's 9OZYJ" and wondered if these would be sufficient? I do have two 120W motors from the aforementioned website, however, felt they were possibly too low powered anyway.

I am unsure what to go for, but am erring towards a 3 DOF version; but again, it's early days and just wanted to get some motors to play to start with and then start developing from there.

Would the motors be sufficient; I do note it doesn't mention the torque on the eBay post; but everything else seems to be in the right ball park from what I have read elsewhere.

Does anyone have any advice?

The 120W motors are unlikely to be too weak for more serious applications.
You gave too little information about what you want to build, 3DOF can be understood differently e.g.:
2DOF (pitch, roll) + loss of traction
3DOF (pitch,roll, heave)
Write exactly what you want to do.

Sorry, early days for what I'm doing.
It will be for a car simulator, and the hope also for Elite Dangerous as well - potentially at least.

In terms of what I'm after, I have seen ones where the motors are positioned in a triangle, with the 'seating' area being raised in a similar triangle manner to create pitch, roll and heave.

I will be wanting to mount the chair, 'wheel/gears/pedals' or 'joystick/pedals/throttle' as well as a monitor on the movement jig - the usual things really.
Sorry, I know this is a little vague, I'm trying to work out what I'm after really; it's a simulator for my son and he's a racing fan; but I do fancy a go and I'm Elite Dangerous!
So the primary notion will be for a racing simulator.

A tough topic with 3DOF as a first project.
You definitely need 400-500W motors to efficiently lift the whole thing with equipment.
Do you play along with your son in VR ? or on a monitor ?
The question is whether you have the ability to weld or rather construction from aluminum profiles ? (Aluminum will be quite a bit more expensive).
Here is an example of a well-documented 3DOF aluminum build thread.

And the most important question what is your budget ?

You might also consider building a simpler design that doesn't require such powerful motors.

I built one with a buddy and for racing it's really great. and you can fly it in ED too

I have used VR; I don't use it regularly, but do intend on having a go with the set up.

Do you think those motors would be OK?

The RPM at 120rpm and 400w?

I can't answer the question if the motors you want to use will be suitable, I didn't build 3DOF I have 6DOF on 250W motors.
I'd more like to tell you that building a DOF is a certain process and it's worth reading as much as possible from the experience of other users at the beginning, which will later save you a lot of time and help you avoid mistakes.
see that in this thread

Sebastian, despite undoubtedly a lot of knowledge, had several problems during the construction and partly had to change the finished project.
My 6DOF cost 800-900 USD , so feel free to specify what your budget is on this forum there are both low cost projects and machines for thousands of USD.
What motor controllers do you plan to use ?
The question about VR or monitor was due to the fact that if you are going to mount a monitor on the 3DOF it is an additional weight that should be taken into account.
See these threads first built 2DOF then added 3DOF , motors 440W 60 RPM , weight 75 Kg without monitors, looking after this your motors have too much RPM optimum is 50-80 RPM.

Honestly your set up and cost sounds almost perfect!
I guess, in an ideal world, I'd find someone like yourself who has produced a shopping list and an outline of how they did it and go for it.
I do see lots of tutorials, but not many saying - click this link for motor X!
