Has anyone tried using one of these esc's from ebay before?

No, you can’t.

It can’t, but it won’t fry it either. They’re set up for different speeds basically- I have the dual belt ESC, and I gave it a try with hub motors. It works, but there’s basically no torque, since it’s expecting a 3:1 gear reduction. But again, still worked, and had a pretty terrifying top speed. I had it on a short board…so many wobbles. So, so many wobbles.

I think the other way around might work better? Because then you could play with the gearing a bit to fine tune it. It felt like it was pretty close to being functional, but not quite good enough to want to ride it around too much.

The esc type won’t affect how much torque it puts out it depends on you hub motors, which were you using?

I got the dual belt setup from DIY eboards, and I’m comparing it to the the dual hubs on a meepo (same ESC in hub mode). I hooked the belt ESC up to some koolwheel hubs I had around, and that’s how it rode- super high top speed (but perhaps part of that was just how it felt being on a short board?) and no torque at all; very slow start, couldn’t really handle hills. Same ESC is now driving a belt setup and feels much better.

I think they do something with the current regulation depending on type of motor used? Sensored vs unsensored motors might also be an issue? I’m not saying I’ve performed definitive experiments or anything, but it was a pretty noticable difference

Ok. The reason it was so fast is because the rpm limit is set higher on the belt at around ~6000 where as on hubs it is lower because they use a lower kV

Didj someone tried this dual ESC but to use it only with one motor? The plan od to build first single setup and add second motor later on.

@LukePL You would destroy the ESC if you would use it like that… you can buy single motor ESC and later add another one with motor and just use reciever signal amplifier :slight_smile:

The seller said that it would work with one motor. Well according to a post a while back

Thanks guys but now I’m even more confused :smiley:

Currently using a dual one with just one motor. Everything is fine

Okay, I am probably wrong, sorry :confused:

Any idea where to get larger motor gearing (say 20tooth) and the subsequent larger belt from, for reducing the gearing ratio?

pulley just change to these grub screws

What pitch pulley is it?

This is great, thanks. Any idea on the longer length belt?

use this calculator and input your pulleys, pitch, width and center distance(for this you need to have a motor mount). then just google the belt or ebay or aliexpress

I am debating on buy a dual version and used it as a single motor too. Do you see any issues using the dual as single?

Theoretically it should be the same as using a single. Just leave the second set of phase wires disconnected. And make sure the set of unused phase wires don’t short together while you’re running it, it’ll probably kill the ESC if that happens. The cooling might be slightly better on a dual cause it’s designed for 2 motors, so you may see slightly better performance under high loads, or climbing hills (if this ESC can even manage that), but other than that, should be the same as a single

Nope, should be exactly the same. As pennyboard said, just be sure to insulate the unused wires from each other; a short would be bad. I wrapped them in electrical tape and have continued to ride without issue; and when a new motor comes this week, I’ll just plug it in and go back to the dual setup

Me too - ebay dual esc with a single motor. Worked fine out of the box - took <60mins with a roll of duct tape to get out riding. Bargain.

Now to find a decent build plan for an evolve gt type setup.
