    I have a pair of Formula 3 tubs that were raced back in the 90s

    One of them was raced by an ex F1 driver and is very authentic.

    The plan is to use r factor with an arduino and some h bridge motor drivers

    The plan is to mount a universal joint under the driver and have 2 linear actuators attached to the rear of the tub.

    The questions i have are :

    Should i use 12v or 24v ?
    What linear speed do i need in mm/sec
    What type of stroke is suitable ?

    If you're planning to use the motors behind the green one, you'll have a field day!! ;)

    Hi Guys

    i weighed both ends of the tub today

    the rear is 19 kg
    the front is 16 kg
    total weight 35 kg

    with a 16 stone driver inside

    rear 92 kg
    front 47 kg
    total 139 kg total

    is this heavy for a sim ?
    does this limit the type of motor we can use ?

    I have 2 x 300w motors from electric vehicles that have a sprocket on one end and could be mated to some chains and drive sprockets to drive an arm up / down

    they look the same as this -- http://thumbs4.ebaystatic.com/d/l225/m/muWSzKtqxWx9_x-6SKDRsBA.jpg

    why not just remove the sprocket and replace it with a lever. BTW those tubs are DOPE.

    139 kg is a fair bit and you still need to add the weight of peripherals, but enough power and leverage anything can be made to work.

    Is there any other specs other than 300w listed on the motors, like rpm and torque?

    not sure the motor will have enough torque to drive a arm without a gearbox

    --------------------------------------------------------------------------------------------------------

    I will find out more about the motors rpm etc

    ah.......
    you will probably need gearboxes.

    Do you know how fast they switch direction when you reverse +/- ? I find the more powerful the motor it seems to need to come to stop before going the other way. Not good for a Sim.

    I can't see a nm rating on the motor specs.

    I know you already have the motors to hand, but if you are thinking of buying, consider these ones from a UK supplier:

    http://www.motioncontrolproducts.co...-motors-and-geared-motors.php?cat=1.php?cat=1

    They match what the majority of us use on here. Anything around 200W with 50:1 / 60:1 boxes and you'll be sweet.

    Given the weight you wanting to move around, I'd steer away from 25:1 boxes.

    thanks for the advice from everybody :)

    i am leaning towards the motioncontrols motors and a 50:1 gearbox

    i found a little more info on the motors i have - they may be 200w or 300w and run approx 2750 wth no load
    http://www.petrolscooter.co.uk/elec...-volt-280-watt-11t-chain-sprocket-zy1016.html

    the motor sprocket has 11 teeth and the larger sprocket has 52 teeth so i will need another reduction gear to get it working i guess.

    Good luck with the PSUs. Please tell us if your still alive when you're done connecting everything;). This looks like a cool project though. Keep us updated!!

    The short term plan is to get one working and let my son have some fun with it.

    The long term plan is to use them as training simulators with a professional driver who logs in to advise the students

    Attached is a pic of a kart sim i built for my lad over a year ago. The plan was to motorise it but he was not keen

    Just to clarify, is the long term plan to possibly use them commercially?

    If so your thread would need to move to the commercial thread section and the Admins @Historiker or @Race Ray can help with that.

    @Gadget999 is it your intention to create some type of for profit enterprise (selling or instructing) with this project?

    No the driving trainer is a friend of mine who lives abroad.

    He can give my son some coaching over the internet :)
