Re: QS 3000w midmotor

My 1000w qs middrive motor came with this 8mm pitch timing belt pulley. I think the 2000W and 3000w motors will also ship this way unless you plan otherwise with the supplier. I ordered from Alibaba but see no real advantage of doing so. Special requests would likely have to come from qs motors dire...

Re: Calling all Belt Drive Experts

Can you design your bike motor to not need an idler? I'm planning to avoid them if I can. It looks like the same 825mm belt can be used both with and without an idler. And the belt is only $10.98 at V belt supply! Belt Length a.jpg FZBob Nice Cad work. I forgot about the black background. Do you ha...

Re: Calling all Belt Drive Experts

FZBob That does look like the pulley. Can you design your bike motor to not need an idler? I'm planning to avoid them if I can. It would be easier to add the 2nd flange as a seperate part. It would need support printed with the model in the tooth area, that area is too small to work. Could be a bash...

Re: Calling all Belt Drive Experts

lets try it It feels very strong. I had to slow down the print infill and put tape on the bed leveling screws as the printer shakes like crazy when printing the teeth on the pulley. A good challange though nonetheless. So one failed print attempt. Actually printed in 7hrs 49 min. Remember larger pri...

Re: Calling all Belt Drive Experts

I use ViaCad Pro 9 for my CAD work. I sliced the 120 pulley and it came out to 9 hrs and 22 mins. This is with a .3mm layer height and a solid fill for strength and machinability if needed. 60mm/second for all but first layer, PTEG. This would be $140 using my pricing scheme. I'm sure I can do some ...

Re: Calling all Belt Drive Experts

Qs motors are now selling motors for mid drives that were originally set up as belt drive. I’ve ordered the smallest 1000w version. I’d expect to see more belt drives in the future, at least for the primary reduction as mr magnets states. In the market for a 3d printer look at the alfawise U10 from ...

Re: new cyclone 3000 w mid-drive kit?

I don’t think anyone is selling decent, proven cyclone mounts. Sick bike parts and Luna cycle have versions but they are untested and reviewed here in ES. Sick bikes looks like the standard mount that maybe just does not come in the kit. Luna’s looks promising just not my thing. I got my hands on on...

Re: What's the deal with ordering from QSmotor?

Saw a $50 difference from one to the other as one had high shipping for the kit and the same shipping for just the motor ,$150 extra...

The controller is what comes with the motor, GB7280MF Sine wave controller, it states.

I hear you on the motor sizing, baby steeps. And the budget is always a constraint doing personal R&D. Trying to keep it a bike at this point.

VasiliSk Just ordered the qsmotors 1000w motor and controller from alibaba. It would probably take one of your smaller controllers as the max amps is relatively low.

Re: Made for each other?

Use a domino throttle. Easier. Simpler than the controller upgrade. Worth the $100 to have the best. Use a trim pot to limit the input voltage a little or max throttle gives to much power and shuts the controller down on you. Drop the 5v to 4.8 if I remember correctly. Still has some dead spot in th...

Re: new cyclone 3000 w mid-drive kit?

Tommm Are you trying to limit or govern the speed of the cyclone motor? I had to install a trim pot or adjustable potentometer to a domino throttle to get it to not cut out at max throttle. Was sending 5v and I needed 4.8v if my memory is correct. The input 5v voltage to the throttle was lowered jus...
