My first build. Another budget flightsim 2DOF rig.

I think our motors are more like 50:1, but I would think the higher the gear ratio the better, as long as it doesn't have lots of backlash. The problem is that we're trying to use traction-type motors for a task they weren't designed for and so it's a bit of a lottery as to how well they'll work.

One (probably daft) idea I thought about was using two cheap and preferably slightly dissimilar motors to drive each axis. The torque ripple of the two motors would likely not be exactly in phase and the effect might be to break up the rhythmic steps into a more random and less noticeable effect. I don't know if this would work but if you've already got two undersized motors it might be worth trying.

I coulda sworn I saw they were 300 or 350 internal rpm somewhere, but now I don't see it. *sign* Well, I wonder what the ideal solution is.

I was wondering if there was a way to rig up a toothed rod or rigid chain or something that a sprocket or gear on the motor shaft would directly drive up and down instead of a rotating lever. You'd lose speed (unless you used a large sprocket), but you'd gain that torque and most of all you'd have no limit on rotation distance as it wouldn't lose efficiency or reverse direction after 90°. If you wanted some speed back, you could use a larger sprocket. Similar to an actuator I guess, but not screw driven.

I have just received these motors, but I think I purchased too quickly as they are very small and only output 6 N-m each. The shaft diameter is only 8mm lol. And I was thinking my motors were only 5:1 for some reason. They do have this 96:1 at 41rpm and 21 N-m which I think would be enough for my 400lb upper rig. But now I'm wondering if it would actually be better?

What is the angle of the motors' movement are you using? If you can shorten the motor arms and increase their rotation angle to recover the lost seat movement then this will increase the apparent 'resolution' of the motors and reduce the steppy feel. This is what made it tolerable for me.

How are you going to control these motors ? they are brushless motors.

40+/- I've shortened them from 65 to 55 and it made no perceivable difference.

Are they not the same as the wheel chair motors? I saw that they "required" their controller board but I was thinking I could just plug them into the ibt2 instead.

Something like a steering rack:

DC brushless motors are much the same as ordinary brushed motors except that the mechanical commutator and brushes are replaced with an electronic switching circuit that does the same job, and often doubles as a speed controller as well. These motors always need to be paired with a suitable, sometimes proprietary controller. A brushed motor controller won't work.

Well crap.
