Question Need help with a DD DIY Wheel I'm planning to build

Sorry mate. Didn't miss it. Was just gonna respond when I've got the dd wheel up and running. As I'm a bit undecided on which one to settle on.

At the moment I've been using a 600w 24v power supply but I've only found out from this forum recently, that it's the current that provides all the torque. So I could go back to 12v 600w power supply and get the same torque, while using less power, which I guess will generate less heat.

I'll let you know when I've bought the 12v power supply, if it's any better to use. It's just a big waiting game at the moment, as it's Christmas.

Sure man
From what I've understood, most people go with 12V 80A or 12V 1000W if they're going the Direct Drive route BUT it's too expensive for me, so I would love to know if 600w is enough

With 12v its 50amps, why not? But that also will depend from the motor too not only from the power supply.

I think I will be using a MY1020 36v 500w motor, what would you recommend?

i advise to do yourself a favour and read finaly the manu79's complete thread the forum i mentioned. It has all.

And try to take the lightweight wheel itself. Say, 1kg max. The lighter the better.

So 12V 80A? I found a cheaper alternative to finding the components for cheap, which is Ali Express, including the 48v 1kw motor, so I will be going that route, since I do plan on gaming for long hours

Does anyone know any good model names for a 12v 80a power supply?

The only cheap and reliable solution is to find a server power supply

I did a search on those model numbers, all 3, and couldnt find the exact one he was using, based on his photos at least

then you can find the PSU first and before buying it, ask question if the pinout is known in a new thread of this RC forum

I think in the Cousin of OSW thread, someone mentioned that a 1000w motor can handle about 200w of heat at stall. I guess that a 500w motor will handle about 100w of heat at stall, which is too little. I have the 1000w my1020 and a fan sucking air through, and it gets mildly warm after driving for a while. If y0u go with the 500w, i think you need to have real good cooling or use little torque (but then, what's the point?)... so, go for the 1000w.

For the power supply, I'm using a DL580 G2 HP power supply 870w. I believe there are 2 versions, and the one i have is the big and heavy one (so, it's off the rig). The wiring can be found online on the rcgroups. I have the 1000w my1o20, and it runs it without any problems (i use 2 ibt-2)

I don't know if you have considered this, but you need buttons on your wheel. You can go the wires or the wireless route (for example, buy a cheap wireless controller and mod it on your wheel). I went the wire route with something like this:

Ahhhhhh I can't get the link to post... it's a replacement mic cord that is coiled.

It only has 6 wires, so I have 4 working buttons including the shifter.

Ah, so yes, you also need to figure out how you are going to make the on-wheel paddle shifters working. What I did was salvage a used wheel with paddles, and rewire the insides with the mic coil cord. I'm sure there are other ways to do it...

Here is a pic of what the mic cord looks like:

Brother drive link is not opening and I want ot see the process
