    Hello
    Great project Sebastian2
    Is it a good idea to use 48V motors?
    Do higher voltage motors need lower currents on the regulators?
    Will they work properly?
    Best regards

    So you have 48v regulators? So why not. I think the psu will get more and more expensive? Maybe at some point you get fried if the rig has a malfunction and a Short to ground or you

    Yeah, I think 48V PSUs, drivers/regulators and motors will be harder to find (and more expensive?) than if you used 24V (or 12V).

    If you manage to find some and run into trouble, you are much less likeley to find support by users that have experience with the parts you use (or similar ones).

    So what are the advantages of 48V? You can run cables with a smaller diameter. Can't think of much else. This might make setting up the wires a little easier. But the type of insulation on the wire also affects that (silicone insulated cable is much easier to bend than regular cables).

    All in all, the risk/reward balance for 48V doesn't seem good to me. If you stay in the range of roughly 250...750W per motor, 24V makes much more sense (in my opinion).

    Thanks for the tip

    I was guided by a smaller current and therefore smaller problems with reverse currents

    Sebastian2 your project is perfect for me.
    Do you have a recorded video of the platform in action?

    Would you be so kind as to share the electrical diagram?

    Best regards
