That $300 price tag is a bit too high for me right now. If you think you may go for higher power and performance levels in the future, then money spent on a quality controller is well worth the investment. At modest power levels throttle control and being able to tune various settings doesn't matte...

To calculate power in using phase amps I think you'd have to multiply it by the "apparent voltage" that the motor "sees", something I have no idea (or need) how to measure. It's simple... battery Voltage while running times battery Current. Since no load current is so low the copper losses are minus...

What motor to use really depends on how small a diameter tire you can live with. Gravel roads, scrub, desert and forestry tracks, badly surfaced roads, to me means 20" will be too small, so 24-26" outside diameter? Thinking fatties, at least 2.5" tires? > You also have to look at the top cruising s...

Sounds like a great setup! Feedback from anyone in the below most welcome dual 12F Nucular controllers on my 98kg workhorse scooter. The perfect throttle control and variable regen on it makes the others unpleasant to ride in comparison Is that because the Nucular is true FOC? Are these features / ...

The Nuc seems to have it running more efficiently in terms of iron losses, and your extra copper will definitely help current handling while under load by reducing copper losses. What's the Nuc display saying is the new Kv with the rewind, so we know the rpm to go with the 6A no load? Were you worri...

why the little hole and hacksaw cut from the clamping area, is that to help in clamping pressure or a controlled stress crack? The hole was to prevent a stress crack, but I haven't done the drill holes, since the 2 earliest pairs of torque dropouts, as they're probably unnecessary with steel. The c...

What's your current setup like? How do you go about charging? I pretty much stopped using my other ebikes since installing the dual 12F Nucular controllers on my 98kg workhorse scooter. The perfect throttle control and variable regen on it makes the others unpleasant to ride in comparison. It's run...

I still think you're making the same mistake as the big car manufacturers who are trying to maintain the status quo but with electric drives powering the same heavy wasteful cars. Electric transport should better meet the actual transportation needs while also making better use of the world's resour...

This is a case where the proverb "It takes a village to raise a child" comes to mind, and we the village should be allowed to do so. We were proceeding nicely with a number of villagers stepping in with calm and reasonable posts before the lock and hack job on the aftermarket motor for SurRons threa...

Charging a 40ah pack in 10min requires 240A of charge current, which just isn't realistic. Long distance trips by electric require a different approach to travel. That is to stop and do something interesting while your battery is charging. I used to take the drive straight through approach to trips....

When did the idea of the original thread poster having control of who and what gets posted in the thread come from?...

That's a new concept to me too, and one I completely disagree with.

Instead of the doghouse, out them in the Octagon. Their own private thread where everyone else can watch them burn themselves out o...

... "better pissed off than on"..

True, but it sounds like your brother got both.

That motor is a nice motor for direct drive washing machines, because it's large diameter makes it capable of delivering enough low speed torque to get a heavy load of wet clothes moving without a gearbox, and because it's cheap. Plus it's capable of high enough rpm for the spin cycle, that you coul...

how petty can one get.. just call you Richard?? it's not about supporting anyone, but operating without the forum rules and etiquette;) Spoken as a true ElectricTrump fan. Are you sure you got the wording right in that last sentence? Throw in some whining about being attacked to go with your weak n...

Also, just to clarify something now. Since he insists his chosen name was done in jest, then jokes related to that name can't be personal attacks. On the subject of personal attacks I don't think anyone other than ElectricTrump himself has posted language worthy of threadlock in any of the numerous ...

Ok, plz feel free to go outside and play with yourself for awhile lol..

..and in pops the only type of supporter that ElectricTrump has...LOL. Please tell us more.

John in CR. You are a very valued member of ES with a long history of posting valuable information based on your real-world experiences. You've been asked politely to avoid posting in EG's threads (I saved the PM's), and EG has been politely asked to avoid posting in your threads. And yet you just ...

Is anyone running dual Nuc's and having issues with crazy wrong stats for some of the line items in General and User stat pages that they can't reset? Does the "Master Controller" setting do anything if you're running the inputs directly to the display?

I'm running dual 12F Nucular controllers on a stock sealed HubMonster at 20kw peak input (pushing a 110kg bike geared to a max speed of 130kph), and a single 12F Nuc at 10kw peak on my son's MUXUS 3k speedier wind in a 23" OD 18" moto tire (geared to a 95kph top speed). Both bikes have 21s packs, an...

If all settings equal other than phase current limit, then current is ramping up at the same rate, so the higher current takes a longer period to reach there. Also, some motors are wound in a manner that they work properly in only one type of termination. I remember when some guys were exploring Sta...

Thanks for sharing all that great info. I looked at the thread just in time, because silly me was actually considering building an 18650 pack for my son's ebike. Now I'm going with my original plan which includes having to do a bit of cutting on the Phazor frame to make room for automotive grade cel...

So to clarify, the Nucular controller requires DC input, and will output a voltage higher than that input voltage, boost conversion only? And let you arbitrarily set a custom voltage? And let you de-rate current amps? So a pair of PSUs each 3kW outputting ~48Vdc, gets converted to say 90A @58V, or ...

Now the thread is locked again with only quite civil discourse in the new posts...what gives? If you want a child to learn to play well with others, then you have to let him or her actually play with others. This nervous mommy stuff will never work, whether it's the mommy being overly protective or ...

Hubmotors for wheelchair already exist, though a pair of hubmotors designed for golf cart size vehicles may be more suitable for your off-road mobility unit, including really wide tire selection. There's no need to pull off some axle conversion.
