    about to buy my first set of motors !

    what sort of mm/sec and stroke do i need

    i am planning on a 2 motor rig first time round

    any suggestions greatly appreciated

    What motors depends on design, budget and availability in your part of the world.

    Motors need enough torque for the anticipated load, given the inherent leverage of whatever design is chosen, and you want speeds above 150mm/s for good motion: https://www.xsimulator.net/community/faq/speed-needed-for-good-motion.218/

    Best to post your design first, then decide what is needed to drive it.

    You have not stated the mass of the tubs nor the intended design for movement, though foot or shoulder mount would be the best. You also need to know the specs of the motors you intend to use to work out potential suitability: https://www.xsimulator.net/community/faq/calculating-basic-linear-speed-and-forces.89/

    My best guess would be that wipers are likely not a good choice, given the additional mass of the F3 tub, plus user, plus peripherals. I suspect that once you work out the actual design it would likely need powerful DC motors where you have a choice of ratio from 25:1 - 60:1 like these:

    www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html

    Or these:

    http://www.ebay.com/itm/GEAR-MOTOR-...hash=item5684db6428:m:mp3J8Jo4s_uQ5iKL4cWuspA

    Though a bit noisy another cheap and powerful option would be winch motors: https://www.xsimulator.net/community/faq/dc-winch-motors-for-motion-simulators.151/

    Or alternatively high efficiency DIY actuators tailored to the load and design: https://www.xsimulator.net/community/faq/diy-linear-actuators.248/

    Hi Noorbeast

    thank you for the information, there are a good few options there

    i will weigh the tubs later and find out the mass

    i have some 300w 24v dc motors lying around from an electric kart - they have a sprocket on one end and if i had a gear attached to a threaded bar i may be able to build a powerful actuator (i also have some hydraulic rams but not sure i want the complexity of hydraulics !)

    i will get some weights and pictures up soon
