Re: Looking for a strong headlight

Two expensive but very good lights: Supernova M99 Pro (449€) https://supernova-lights.com/en/products/e-bike-lights-45-kmh/m99-pro/ Daytime running lights, low beam/high beam 24-60VDC (75V max), so you might need DC-DC converter if pack voltage is too high. From my own experience, it's better than l...

Re: new cyclone 3000 w mid-drive kit?

From pictures it seems the new kit doesn't have second bracket connecting rear of the motor to BB.
So IMHO they made it worse.

PS. That poor sprocket engagement will only become issue on the "walk of shame" scenario :wink:

Re: Portable snow tank for towing skiers

Cyclone 2-6kW is peak power. With some modification and depending on cooling, you might get up to 8kW peak from these.

QS 3K mid... Folks here have pushed beyond 20kW and still haven't overheated it. So far haven't heard any cooked motor.

Re: Portable snow tank for towing skiers

VESC should be capable of either with custom app or external controller. Custom app running on VESC CPU('s), keeping both RPM's equal, except when steering. Input through ADC or PPM/UART/CAN. Or VESC constantly reporting to master controller RPM/Amps/etc, which then controls VESC's. Comms through UA...

Re: Portable snow tank for towing skiers

Hall senators give you that feedback, right? Motor hall sensors give feedback to motor controller (vesc) for timing. Not (servo-like) position you need for your master controller, which has to keep the speed exactly equal. Also, what do you mean by “hall sensor signal noise?” Cyclone motor-specific...

Re: Portable snow tank for towing skiers

With PWM you'd need some kind of feedback of the actual RPM or you need to correct your steering constantly to compensate one motor going faster than the other.

Re: Portable snow tank for towing skiers

With QS-mid you'll need reduction, possibly two stages (unless you mean the one with internal 1:2,35 reduction) to get the rpm down, unless you want to go really-really fast. IMHO two Cyclone 3k/4k motors with it's internal reduction of 1:6 would be enough but not sure about pairing those with VESC'...

Re: MY1020 Oil or Water Cooled

Use thermal potting compound (I'd suggest polyurethane) to pot the stator windings. Secondly, use temperature sensor and a controller that either dials back power or cuts it when reatching upper temp. limit.

Both, good bonding and good thermal conductivity are important in this ap...

Re: new cyclone 3000 w mid-drive kit?

The cyclone planetary is 5:1, not 6:1 they state that planely on their website. Cyclone 3k planetary is 6:1 unless they have changed/redesigned it completely. I couldn't find any info about it on their website. PS: From experience, I don't agree with your claims about q-factor and loss of efficiency.

Not plug-and-play; you still have to re-solder connectors. But it works very well and has enough power to cook the motor.
Thermo Nucular 24F
Same as above except instead of cooking you'll either melt or explode it (unless you can resist the temptation to crank up phase/bat amps).

Well, theoretically, everything is fixable but it will cost you at least 10x more. http://cyclone-tw.com/motor.html Here it lists planetary gearbox for $99 (6th item from the top). I would contact them beforehand, to make sure it will fit your motor. Make sure to ask, whether it includes planetary g...
