new to sim

Good! I hope the torque will suit your needs!

Could you do me a favor and crack them open as well? I am very curious what they use for component material. If they are metal geared than these motors are a super deal.

they are out for delivery today. I spoke with the shipper and these have plastic gears . No lose as I can use them elsewhere in my shop. I'm waiting on a response to see if they stock any with metal gears.
Here is the other one I originally posted about purchasing and it has metal gears. Can any one give there thoughts on it.

Hi Tendonitus, just because they have plastic gears do not rule them out. True they will having a higher failure rate on the hard reversing moves but that does not mean that they will indeed fail. Since you have them, give them a try. The other motors that you linked to seems ideal. I wonder what the motor wattage is without the gear reduction and what the gear reduction ratio is. But it really does look like a good motor.

@Historiker , 12v x 12 amps = 144 watts motor, approximately, now overdriven at the rate of 2.5 - 3 times rated power puts it about 432 watts ish.

Sorry, I meant RPM. But thanks for clarifying that.

read the link - 179 rpm.

that looks ok, motion dynamics motors here in Australia have plastic gears inside, but its an industrial plastic, not nylon based. As long as you do not have a huge load on them, they will be fine.

the other motor is showing only 35 inch lbs vs the ones above I bought at 30 -40 n.m or 22 - 29 ft lbs. Before we get others confused, is 35 inch pounds enough?

thanks David

I read the link, thank you Dave. But the link does not say either the motor RPM nor the mechanical advantage of the gearbox. It gives only the output RPM. Again, thank you very much for your input.

sorry, my mistake, I am guessing and that is a guess that the gearbox is probably 25:1 maybe, making the motor itself about 3000 rpm ish.
Mechanical advantage of gearbox is you "hope" its stronger.
Realistically with sim use, things will wear and break after time, metal, plastic or any internal or external components.
People need to treat a sim like a real car, expect maintenance from time to time. Loose bolts, broken welded, glue come off, parts failures, rod ends flogged out. But overall, a LOT cheaper than a real race car and if you crash, you hit reset.

Thanks, I was estimating around 3800 or so myself. I have a feeling that the motors on both sets linked are actually the 90watt Chinese unit found in many if not most low cost assemblies, including the three different types of winches that I have. I wonder how accurate the 12amp claim is.

not sure how to convert this. Maybe @Historiker can help, he is a teacher. Nut if there is 12 inches per foot, then 35 inch pounds equates to 2.9 foot pounds per torque.

lol, I teach college history. My math ability is limited to the number of digits on my hands and feet.

I know I' m not bsft but for a 2dof it probably won't make any difference which way you go with the moving or static screen for roller coaster simulations. But for 3dof with heave you would definitely benefit with a moving one. Here is my 3dof with heave and a moving screen with nolimits for example. Sorry for its low resolution.

Correct! Not much power or torque there at all!

Thanks for answering this

funny enough, I was just listening to a science talk back program on radio and they talked about the current numbering system is basically based of that fact we have 10 fingers.
