    I have no idea how matters have progressed in this area but for those who are interested in using electric battery operated drills and/or car jacks might well find the following jack a very good starting point for their platform.

    I have removed/modified a gear to increase the speed and managed to mantain sufficient torque to move a balanced experimental platform quickly!

    I have not persued this solution as I have some other alternative in development.

    We had an old motorized wheelchair come in to be demolished and I took the 2 motors from it. They are 12 volt motors and they should provide plenty of torque.

    wormgear reducer and motor from china

    Hello everyone,
    I am new to this site. I am glad i found this forum. I am been dreaming of motionplatform for a long time. I made some queries to China about wormgear reducer with motors. Prices ranged from 67 us dollars to 135 . motor ranging from 025kw to 2.2 kw. Output speed ranging from187 to 23.those same wormgears witout motor where from 37 to 67 usa dollars.
    what price range is westernmade motor wormgear reducer units.
    could someone shed some light to question what kind of motor reducer unit would be optimal for 200 kg to 300 kg payload platform.

    "Pipe Dream"

    Hi guys, I once thought about building a full motion sim but it always ended up in the too hard basket where it still is today, but I am an engineer employed in the water industry. (pressure control valves, chlorination, chemical dosing). I appreciate fully what you are up against and offer this idea. My pit is on a steel frame and I guess it would be approaching 500kg with two people on board. If you have this type of weight balanced on your pivot point it doesn't take that much force to move it as I'm sure you all would know. I once contemplated using an inflated tractor tube as a pivot point and linear actuators (hydraulic rams) to move it. Not the hydraulic type, just simple cylinders made out of 6" diameter PVC pipe with a chevron and piston. These could be actuated using water pressure from the house with 24v retic solenoid controls. Imagine the lifting force of average domestic water supply at approximately 30metres/head acting on a 6" cylinder, this could lift a car for a tyre change. Speed could be controlled by flow control valves on the cylinder lines and construction would be relatively cheap. Exhaust water could be fed to a tank for recycling. There are water powered actuators already being used to open farmers gates etc. I know it's not a good idea to have water near the electronics of a sim but it may be a plausible idea, who knows. Good luck to all the 'motion' crew...

    Hi Simppa,

    Not sure if this thread is still active. Those prices you quoted are fantastic! Can you tell me the China source? Thanks.

    Cheers,

    The following link is to one Chinese manufacturer.
    http://www.jiaoxing.com/ep3-04.htm
    They quoted the following

    NMRV050-25-F1(OUTPUT FLANGE)-0.25kW motor USD67.05/SET
    NMRV050-25-F1(OUTPUT FLANGE) USD37.05/PC

    NMRV050-10-F1(OUTPUT FLANGE)-0.55kW motor USD78.05/SET
    NMRV050-10-F1(OUTPUT FLANGE) USD37.05/PC

    NMRV063-20/30-F1(OUTPUT FLANGE)-0.55kW motor USD91.56/SET
    NMRV063-20/30-F1(OUTPUT FLANGE) USD50.56/PC

    NMRV063-60-F1(OUTPUT FLANGE)-0.25kW motor USD80.56/SET
    NMRV063-60-F1(OUTPUT FLANGE) USD50.56/PC

    NMRV075-7.5-F1(OUTPUT FLANGE)-2.2kW motor USD135/SET
    NMRV075-7.5-F1(OUTPUT FLANGE) USD67/PC
    I am not sure if those applicable to motionplatform. My platform is still under planning stage.

    Thanks simppa. Have you bought any thing from them? I know that most China manufacturers aren't interested in small volume sales. There are only interested in container size sales

    Hello all,

    I'm following Ian, Jim and Roland's platform development closely. Yep, the bug has bitten me as well.

    Would washing machine motors be suitable for a motion platform?

    Thanks in advance,
    Gerhard
