snc5 cheap alternative -Gseat project

hello i need an advice. i built years ago a 3 dof SNC5 motion rig. For simplicity sake i want to use the same type of interfaces(USB-RS485). I know these questions were often debated, but i also know technology in sim racing progress exponentially. so my question is there a cheap motor working the same way as the SNC5 or SNC6 with very short through for a Gseat project that would aslo be fast enough
in this application i d need for 4 (2 +2) motors that would move about 30 kg for the butt and 10 kg for the back.
through would be 1 to 2 cm
I am not sure about servos as it seems they tend to fry on me especially if the arduinos are not well programmed

thanks

DC motors seem to much bulky and heavy. something more lower profile woul work better?

It is an interesting alternative but neither is it cheap. SeatTime recognized in the thread.

I have gone for servos for my Gseat (still waiting for final parts to turn up) - cost is always relative depending on your definition and comparison of what is 'cheap'. In regard to DC motor actuators verses Stepper SCNs, constructed properly they are quite fast even under a good load, more efficient than an SCN - I used a ballscrew (around 90%) were SCNs use a acme thread (around 60%), cheaper (but I am building them ), strong and most importantly for me, way quieter than SCNs. Con - as I said, you have to build them...

hello,
any recommendation on the servos (brand and model number)
same for the DC ( DC motor should be low profile)
I guess that s a reborn project ...

I'm trying to keep the weight down, so experimenting with servos - still in testing.

have a look here for an overview of gSeats

Hello thanks a lot for the overwhelming information.
I believe I ll take the route of the DC motors . sorry for my stupid question but is it related to wiper motors?
The servo projects , I am not sure about it. I dropped the project when all the servos died one after the other. It ended up being costly.
any advice on a simple tutorial for newbie/stater about DC motors ?

thanks

Hello , I came across avenga post on his 2 dof with worm motors . It iseems in my mind very doable with worm motors any recommended worm motors ? I d need 4 for 4 axes.

I believe staying simplest is the best way to go

they would have to be fast very small and pushing about 15 to 20 kgs each . I weight 84 kg but I estimate that 15 to 20kg would be is plenty

What do you want to build (I see from your comments not a G-seat)? It will have 4 axis's, but what type of design?

I will probably go ahead and buy a worm gear motor 160 rpm ,12 volt and one JRK 12v12 and do some testing soon
