    I was looking to build a DD wheel, and I found an Indramat MAC 90C-0-KD-2-C/110-B-1 for sale near me, it looks perfect for a wheel, it can do up to 10nM of torque, and it comes with a built in encoder. Now the problem, it needs 100V+ to run by some rough calculations, what controller can put out such a high voltage without breaking the bank. I was looking into building my own VESC with some higher voltage capable transistors, but I would need a schematic that is designed to handle 100V+ and about 17A. Supplying the circuit with power isn't a problem since I'm comfortable with high voltage electronics and will be powering it from the mains.

    My inspiration was from this post:

    Also here is a picture of the plate:

    Thanks for the help.

    you dont need your wheel to spin at 2000rpm didnt you? from the spec i found(is that you? lol) look like this motor has a kv rating(RPM per 1v) of around 16kv for a sim racing wheel rpm that you should aim for should be a round 200-300 rpm so 24v is more than enough current is the biggest part that you should focus on

    link to the spec that i found https://www.reddit.com/r/CNC/comments/yhguvs/looking_for_a_datasheet_or_specs_of_an_indramat/

    Well, after all of that i just want to say that I'm not engineer or anything i'm just a guy all of that come from my experience and me trying to understand stuff oh btw i build myself a hoverboard DD using this firmware https://github.com/o-devices/bldc-ffb-wheel the motor i'm using is a 350w hoverboard motor pair with a 12v power supply it's working great

    Hey, thanks for the reply.

    Yes, that Reddit post is mine, the question on my mind is would 24v or maybe even 48v push enough current through the motor to make decent torque, considering that current is a function of voltage divided by resistance, and with AC motors you have the resistance and inductance to resist the flow of current. But on the other hand I'm pretty sure I saw people use 48 volt power supplies to power the small MiGE (130ST-M10010) which is designed for 220v...

    I am also not an engineer, just a guy trying to build a wheel.
