    Hello everybody,

    Could anyone tell me/point me to a tutorial on how to turn these actuators into a simulator?
    I just need the tutorial on how to connect these actuator to a pc, I already figured how to make a platform I just cant find anywhere how to connect these bad bodys .

    Can you please give a link to the the full data specs of the actuator, particularly the max speed.

    In most cases such actuators are way too slow and hence totally unsuitable for motion simulators.

    This is all I could find about them

    • Max. Thrust: 6,000 N in push application
    • Max. Thrust: 4,000 N in pull application
    • Max. Speed: 13 mm/s

    Forgot to mention that I just wanna try out making the sim with these ones so it doesnt matter if theyre fast enough. I can easily change the motors later if this works out

    Anyway I got some DC motors that have 3200 rpm, 0.73m/A. Guess thats fast enough to go flying through the rood hehe.

    The problem with using those actuators to test with is they are so slow it wouldn't prove much. Maybe with the right linkages they would provide marginal performance for gentle flight sim, but not racing. Then even when you have that working, replacing them later with appropriately fast actuators would require different geometry, even if the actuators were around the same size. Since the actuator is so critical to the design, I would start with the actuator you want and design around it.

    I'm not sure if you were serious about the DC motors, but if you provide some specs we can let you know if those would work. At a minimum you would need a gear reduction to get the speed down to something usable - probably no more than a few hundred RPM. I'm using 41 RPM myself, but most people use something a little faster. If you are saying the ones you have draw 0.73 mA (0.00073 amps) there is no way those would be powerful enough for a simulator. Even at a more reasonable 0.73 amps and assuming a high voltage (24 VDC or higher) that still wouldn't be enough power for a sim.

    Yes I understand that. Anyway what Im trying to figure out is how to connect the motors to the pc so I can use the xsimulator, how to set it up etc. I saw somewhere that I should get arduino board and a bridge for each motor but I need a scheme or a tutorial on how to connect all that and program it. The geometry doesnt really concern me at this point. I just need to figure out the electronics. Later I will draw the geometry in Inventor.

    I already have the gear reductor for the other DC motor, Ill just post the pics so you can check it out.

    I see that your DC motor is 300W, so that should be plenty of power. Your gear reducer is a 50:1, so that should work well also since you will end up around 60-70 rpm.

    Using an Arduino and a Monster Moto H bridge is a common setup, and pretty cheap. But the Monster Moto only goes up to 16V so for 24V motors you will need to use a different bridge.

    This is a good place to start: Here are some options for 24V bridge/drivers to use instead of the Monster Moto: http://www.xsimulator.net/community/threads/24v-motor-driver-where-to-buy.6987/

    I didnt know that. Thanks for the links.
    Do you know anything about the racing cube and setting up that wheel? Would xsimulator be compatible with that?

    RacingCube was designed to work with SimTools, the software available here on XSimulator. I think SimTools comes with RacingCube. @T frank who is a member here makes the RacingCube. I don't know anyone else here who has tried it.

    What type of simulator are you trying to build? Unfortunately those types of actuators normally use a simple acme thread (not ball screw) and nylon nut which will bind and fail under the speeds and dynamic loads required for a simulator.

    Just for the record, Simtools 1.3 is DIY only. No commercial entity has rights to offer it to their customers, period! They must wait until Simtools 2.0 is released so they can purchase the appropriate license from Dustin (aka yobuddy).

    Hi there, what type of 12v motor could I use to replace my 24v motor in my g-loc arcade? is a 300w dc motor enough to run it? thank you in advance
