    Hello,

    me and my friend are working on 2 DOF simulator, that would be used together with Oculus Rift DK2. We want to make full frame design (chair, pedals and wheel on frame) and want to use the following parts:

    -Motor 90ZYT-155 with MCP4 gearbox (2x):
    http://www.ebay.co.uk/itm/12V-DC-Ge...al_Components_Supplies_ET&hash=item58b2cd2323
    -Controller Pololu Jrk 12V12 (2x): https://www.pololu.com/product/1393
    -Hall sensor Magnepot 6120 (2x): http://uk.farnell.com/bi-technologi...sensor-hall-0-2v-20v-to-10v-180deg/dp/2319661
    -Power supply 12v 40A (2x)
    -Universal joint (1x)
    -Linkage ball joint (4x)
    -Thread Rod (2x)
    -Wheel Thrustmaster T500 RS

    We have a few questions, I hope someone can help us.
    -Is Jrk 12V12 powerful enough to drive 90ZYT-155 motor? It says on page that it features 12A maximum continuous current (30A peak) and motor is rated at 23A.
    -How much does point where rod is mounted on frame affects movement. We were thinking of mounting it to middle of back.
    -How long should be lever on motor, around 80mm?
    -Your opinion about setup in general.

    We will be posting updates and pictures as projects progresses.
    Thank you for your help.

    I've just bought that exact motor to replace my damaged drift motor. I will be using a JRK to drive it so will let you know how I get on!

    Those motors have been used successfully with Arduino and Moto Monsters but with a base 23A it could be pushing with it a JRK. I will be interested in your real world tests @SimonUK.

    I hooked up my new 90ZYT-155 motor to my sim at the weekend and its working great! Was really easy to tune the JRK's PID values and its working fast and smooth with no overshooting at all. Really pleased with it :) and am debating upgrading my other 2 motors to the same!

    Great news @SimonUK, that expands the motor options even further for use with JRKs.

    Could you please post a video or screenshot of the JRK graph viewer as I made here to compare your results with mine ?

    My sim is at my parents house so I only get to work on it 1 day a week. I'll try and get a video for you next Sunday.

    @SimonUK Thank you for the update. Nice to hear, that these motors are working good with JRKs. We just got motors few days ago, but still have to wait for JRKs. I'll update thread, as soon as everything is connected and working.

    I have a 2DOF simulator and Oculus Rift and I must say I am not disappointed you going much fun.
    I look forward to seeing your project in your future photo and video simulator, good construction yours

    Is there any other supplier for these motors other then the UK one. Shipping and duties to Canada might be a tad expensive.

    Thanks, had a look and I think I will go for these. Whats the best ratio to go with or what is the most common to used?

    What ratio really depends on what type of sim you plan to build and what weight you are. You plan a full frame so without knowing all the details to be on the safe side I would suggest 50:1.

    Yes he wants a full frame, he's about 220 lbs. Probley 260 lbs max for the motors to move. Were going to try to build it as solid as well as lite as we can. Where would you put the rods, close to the top of the seat, like I see for some of the linear actuators, or mount them lower.....it seems to me that the higher up would be better??

    Yes higher would be better.
