    Hi, i already burnt 1 of my dodge ram motors just during the first tests of my rig.

    Its a pretty heavy full frame rig, around 100lbs with the car seat, foot mount setup.

    Can anyone recommend me some good motors?

    I run a VNH5019 dual motor driver and a 650w 54A PSU.

    Thanks in advance!

    Already did that, but i guessed my motor specs as i dont have them. And i was probably wrong.

    Looks like i need some 50nm torque motors at a minimum to have my rig move as it should.

    Any recommendations for some 12v motors with that kind of torque?

    Thanks!

    Design also comes into it but for more mass you need greater torque, so likely the 50:1s.

    But have a play with SimCalc to check with your intended rig dimensions: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    Thanks Noorbeast, ill get those motors.

    I know there is a Faq thread about fixing levers and pots on the pgsaw but i cant find it.

    A link would be appreciated if someone finds the thread.

    Thanks :)

    When using simcalc, if i have two motors i imagine the output force should be half of the weight of my rig + driver at minimum am i right?

    See the last section of the SimCalc mathematical assumptions explanation: https://www.xsimulator.net/community/threads/simcalc-by-tim-mcguire.11277/page-2#post-140469

    Disregarding mechanical loss, to know what Newtons it will take to move something it will be Mass (kg) x Acceleration (m/s) = F (N). So to move 100kg at 0.7 m/s needs 70 N. It takes 9.8N per kg to counteract gravity. Keep in mind there is significant mechanical loss in things like the gearbox, depending on the ratio you may want to allow between 10% to 50% loss for worm gears and the greater the gear ratio the higher the % loss is: http://www.meadinfo.org/2008/11/gear-efficiency-spur-helical-bevel-worm.html
