I would but I am powering the back wheel of a 3 wheeler, and I feel like it would be easiest to go with 1 really powerful motor over 2 strong ones. But if it comes down to it I’ll go with 2


#4326

For a trike you could always go with a bigger motor like the ones from alien power systems. The 80100 motors output 7,000 watts, which is plenty.

i haven’t tested these motors so I can’t vouch for their reliability. I Know that people use their slightly smaller motors for esk8 though.

Alien Power Systems has been delivering some bad quality lately in their bigger motors


#4328

I’ve just seen a maytech 6880 somewhere on here (no words thread maybe)… maytech make nice motors…


#4329

Yes they do, but the 6880 is nothing else than a 6374 with a bigger bell and an extra big bearing.
So you will not increase the power output with them.
But maytech sells 8085 motors, sealed and unsealed.

I skimmed through some of the older threads about these wheels. What I found was these have different offsets. Meaning some of the flywheel pulleys will not work on this.

Does anyone know which ones work?

Special thanks to @KaramQ for letting me grab these.


#4331

The only pulleys I know that will work are on thingiverse, linked from this thread


#4332

Cool thanks. I was just on that thread too

Getting my guy CNC it for me. Hopefully, it turns out.


#4333

You could also just modify some existing pulleys if you have access to machine shop metalworking tools. Get a regular aluminum pulley from someone like @JLabs and go to town modifying it.

The thing I suggest doing that is make sure you only grab wheel core and don’t grab polyurethane at all.


#4334

I’ll try to do that. I have some of @JLabs pulleys. I really like the modular way to change pulleys.


#4335

I’ve never modified for ABEC-style cores, but I have a tip from modifying ABEC pulleys to fit kegel style cores –

I intentionally put the bolts 1 degree too far on each side, so they really grip the core tight. So half the bolts are 1 degree too far forward on the rotation, and the other half are 1 degree too far rearward on the rotation. Really makes it so there is no slippage at all.


#4336

That’s a pretty good idea. I’ll see if I can draw one up.


#4337

If you end up designing it lmk, I got asked about this wheel yesterday


#4338

Will do.

Damn it 10char.


#4339

The stl files are good I guess but they are stl files. I’m not even sure why websites like thingiverse don’t force you to upload a step file.

So trying to do a heap of reading and research before jumping in too much.

Am I just looking in the wrong place or do lowish kv motors, like 50-60kv in something like a 6355 size not exist off the shelf ?
The idea of a direct drive setup seems really interesting to me but not sure I’m game to rewire a new motor from delta to star / wye and don’t really want to just re-purpose hub motors.


#4341

would a belt slip to the motor pulley side without flanges?


#4342

I have never seen low kv rating 6355 motors. generally those low kv ratings are hub style motors


#4343

I have that style on my racerstars and havent had that problem but I do have idlers on it so it keeps tension on it but not super tight tenshion.
