    Im using these motors now in my testing and im finding that the low holding torque is giving my problems. The motors seem to jitter because the seat keeps falling back on it self. Any ideas?

    The 25:1s are easily back driven but being jittery could be your design, hardware or settings, so can you please post pictures of all of them.

    Thanks for your response!

    I am using a 12v 50A power supply to a MM with Arduino Controller.
    Its not letting me upload photos, maybe because I'm new to the forum?

    Sounds like an off balance issue? I'm using 25:1 and have had them on a foot mount and a Shoulder mount without issue. When powered on, they are very hard to back drive.

    To stop the motors returning to idle after you stop playing a game, you can remove the "Shutdown" command in the Interface settings of Simtools. Or replace the Shutdown command with the Startup command, so that the sim centre's on Exit. (this is what I do)

    Not at home currently, so can't post screens of my Simtools settings.

    Thanks for the info. I'll experiment a little more and upload some photos when I can. I think I'll start my own thread on my build

    What are your motors? Do you have a questions or are you representing a motor?

    Hello I received my new motors from ebay.
    They look good.
    I try them, and I'll post the result 2015-12-05 14.31.29r.jpg

    Hello, it was a question to know if the motors could be good. Now I bought them, and I'll try.
    Thank you

    I must remove the ground inside the motor.

    The motors are only 50W - so do not expect to much. If the seat is well balanced you should have no big issues, but the moves will be not fast like hell.

    Hello,
    Thank you for your message.
    50W It's a mistake. I try the motors, for 12V I use 26A for the max torque that I mesured 18Nm. P=UI = 320W
    the motors use 50W about 4A without load. I put a controller between the battery and the motors.
    I just finish to control them. I Put potentiometers on the back and they look like good.
    but 18Nm it's about 1.8Kg at 1 meter and 40kg at 4.5cm. Perhaps it's not enought.

    Please can you upload a better photo taken by the specs?

    These motors are rated as 50W motors. Even if I would use the rated current of 10A ("Nennstrom") seeing on the specs for my calculations I would not get more than 120W. The 50W is the estimated continuous power, the other values stand for peak and braking. Sorry to say that and you can hope that I am wrong (which is pretty seldom...)

    Hi nikitojm
    extends the power of the motors in your project?
    i´m still searching for a motor that fits.

    I got a worm gear 50:1 12v hallow shaft, having trouble finding the shaft, don't know the correct name. Do you happen to know? Thx.

    @Ryuuken29 - Most members (myself included) have used 12mm threaded rod as a shaft. I think the motor shaft hole is 1/2" imperial, which is about 12.7mm metric. I just inserted 12mm threaded rod, tighten two bolt and spring washers on either side and it's not moved a mm in the year I've been thrashing my sim. :)
