Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

power switch ... It does not work at all although I activated the switch option in the software. No screenshot of the configuration screen, so cannot help. ... the motor stuttered a lot, even with higher power (20A to 30A). The motor spins very very slowly when I press motor when i did the autosetu...

I read somewhere someone was having issues with the PV controller and cyclone motor.
That was me before I got my nucular.
PV works only on trap. mode. IMHO too pricey to get it only because of nice display and some adjustability.

Re: Custom frame for Cyclone Coaxial

Has anyone done DIY motor potting? I have, on cyclone 3k motor. Thermal polyurethane from farnell. Used up one 250ml 2-part bag for it. Mixed and poured in two parts - each motor end in different casting. In retrospect should have done in 3 parts - less messy. 1st casting, made a thin cardboard (an...

Re: I designed a +200A powerstage with 200V MOSFETs

Try flat heatpipes between mosfets and heatsink. I've used those in couple of custom high power LED lights, the heat transfer is amazing.
Mounting will be more difficult - basically; either clamping + thermal grease or just thermal epoxy.

Re: new cyclone 3000 w mid-drive kit?

So I didn't take any pictures but I did figure out what was happening. I took the motor off and took the non drive side cover off and the rotor had somehow slid alone the axle and toward the non drive side cover and so was rubbing on the ends of the windings and the hall sensor mount. It means that...

Re: Nucular electronics - complete kit for ev! [beta]

How well does it work? Is it noticeably better over the stock BT controller? I have no experience with stock controller. I ran mine with PV 12fet (with some issues). Got about a year with alfine 8 speed igh at 70A bat. After upgrade to nuc12fet, igh gave up after a month. Next igh lasted another mo...

Re: cyclone running

I guess it was a sinewave controller, which are sensitive to c3k motor "ghost hall signal" issue, discussed already a while back.
Either generic trap controller or nucular (which filters out those false signals) runs fine.

Re: cyclone running

I'd say it's either controller or BMS issue. No info on either one, so cannot help.
Nothing wrong with motor though.

Re: Non EV LED Lighting PSU Question

I just checked the DRO manufacturers website. All their models accept 15-24VDC ±10%

So 15-24VDC PSU that has input range around 400VAC would do. You could use MR16 socket "halogen replacement" LED bulbs off it as well without problems as long PSU power rating is up to it.

It is 240 vac input
It's the DRO's power supply that has 240VAC input. DRO itself is most probably either 5 or 12VDC in. That's the DRO's PSU output that counts.

Re: Non EV LED Lighting PSU Question

What is the DRO input voltage? Maybe you can switch transformer to one that accepts 300-500VAC.
If it's 12VDC (or close) then you could run your lights off it as well, assuming it's power output is enough.
Here's selection of DIN rail mountable that should work. Just pick right voltage/power.

1) Is there a good current based alternative to stock controller? stock controller controls speed rather than current.
Nucular.

12F if you're bold and do like changing your bicycle drivetrain components.
6F is good enough to destroy weaker links and get maintenance cycle low :D
