Greyborg Cromotor Hubzilla motors, Sold Out

[gensem]

Yay... Do I need brass washers for the bicycle eyelets if I'm using 13-14g spokes?

It's going to depend on the spoke head size. The holes were drilled to accommodate up to 12 gauge spokes. A 13/14 is probably OK, but I'm not a wheel builder so I can't say yes for sure.

I have the first generation cromotor, so im not sure if the holes are the same size. But in my cromotors even the 12g spoke that I got for John Holmes would need washers.

[hillzofvalp]

but do your holes look like one of these:

Hi I was wondering where can I purchase one of these motors and is it possible to ship to Australia cheers. oh and if also if the kelly KHB12301,24-120V,300A,Opto BLDC Controller/With Regen would be up to the task to power the beast cheers.

Is that vs a 53xx or 54xx?

Last year I tried to setup a 144v Cromotor vs 5403 comparison test using identical batts, controllers, and Norco A-Lines - but I couldn't get the Cro in a speed wind that would make it worth my while. In the end the IIRC the 5403 winding ended up having a KV between that of a 5304 and a 5305, so the xlyte wasn't the speed wind I was looking for either, I should have asked for a 5402 (and I considered it). Theres a thread on it somewhere.

I dont think that comparing a 10kg motor to a 15kg motor is fair... but imagine what a bigger (1.5 times bigger) cromotor with the right Kv would do to a 5403/02?

[hillzofvalp]

those videos he posted make me nervous about what I'm getting into. I was thinking about getting an 18FET but now i think I should stick with 12 FETs for my 29er.. what do you think?

i ll say it again... 18fet 4110 is the mininum to wake a cromotor!

[ZOMGVTEK]

18 FET 4110, or 24 FET 4115 would be the smallest I would recommend. The route I would take is 24 FET 4110.

[hillzofvalp]

really?...

I am trying to understand the difference between a 12FET controller with beefed traces putting out the programmed 100A phase and 80A battery current and an 18FET with the same settings. So the 12FET will run a little warmer but is there really a performance benefit?

[ZOMGVTEK]

...You plan on running a Cromotor at 100 phase amps? Yeah, a 12 FET would do the job there no problem.

Whats the appeal of such a big and heavy motor if you're not going to run much power?

[hillzofvalp]

Well I was thinking up to 150A.. But I think I read in this thread that the thing is hard to control even at 80 phase amps!

[zombiess]

Pussycat or monster its your choice and is based on your wheel size, battery volts, amps and phase amps.

With a 29er id suggest an 18 fet minimum. The videos of my bike just illustrate what it can do if you build for pure performance. With 29" wheels your bike will be waaay tamer than mine because you will lose a lot of torque to the ground due to the big wheels. Almost all of my riding is done under 2500 watts. I just like having the option to get crazy if i want to.

Advantage of 18 vs 12 fet is more the 18fet can safely output more amps. Im guessing you should keep you setup below 100v fully and then program it accordingly. I can help you by suggesting settings.

Even on a tame setup this motor will work great, particularly if you are after torque and with a 29er thats exactly what you need. If i let you ride my bike at 80 phase amps you might think it was broken because it wouldnt be anything close to the videos i posted. The controller you use makes a difference somewhat as well. All my stuff is modded and there is a difference between the old eb2xx controllers and the newer eb3xx ones.Both work great just differences in phase amp settings it seems, ive posted about this and have received no answers.

[chroot]

Zombiess, Thanks for the UPS tracking and I am looking forward hand of the cromotors even looking forward to be kick my butt during the riding!

Again thanks Jeremy!

Would it be difficult to get the Cromotor by going directly to Croatia?

I tried to contact http://www.greyb.org/data.html, but it seems they are not going to get worried too much about a stranger wanting one motor for a local pick-up

If You have called on my mobile try again. If you have e-mailed me also do it again. There are some 10 motors left afaik and you can pick it up in Zagreb.

Thank you, I just wanted to know if it is possible so I can adjust my trip eventually. I may be going there in July so I will let you know when it gets more actual. Thanks!

Hey, does anyone know anything about silverrich1, apparently hes selling the hubzilla motor :S Looks abit sketchie. His post is here viewtopic.php?f=8&t=39085&p=585129#p585129

I'm assuming in pussycat mode you would get a better range,yes?

looks reeeaaally shady, I know the folks over in Croatia do some amazing work, ill be sticking with them.

maybe i'll tell people you're charging 280%? I wouldn't mind getting one of those motors and keeping quiet

Hi
Why are you selling these motors for $595 when you imported them for $200 or less????
I kindly ask if I may buy one of the motors for cost price $210 + whatever it costs for the shipping
do we have a deal?

I'm not rigging your outfit, just wondering if you could elaborate further on what modifications have been undertaken by greyborg?



Then you need to contact accountant. Its not my place to say. I'm just a distributor.

Good luck to anyone who orders from China. If Greyborg didn't have the machining capabilities they did they would have ended up with a pile of useless motors. Scooter motors don't fit in bicycle drop outs either, you can build a custom frame or swing arm for a big scooter motor though if you got the skills and save a few bucks.

BTW, I wish I was only paying $210 each as I'm sure Accountant wishes he was only paying that much for each motor as an all in cost, just not going to happen.

I am going to try running it between 60-80A at 120A phase amps to start. I understand since it's a 29" wheel it's going to require significantly more power to get the same results. What is the maximum battery current I can run on a lyen 18FET? If I beefed it up, should I only beef up the main big traces or the phase groupings also? THEN what settings could I push it to you think? (4110s)

Really depends, if one of your banks has a FET that's not close in spec to the others then you can't push it as hard as one that has them matched. If they are all matched closely you can push it harder. If you monitor the temps of high side FETs you can get a some idea of what's going on, I don't let mine go over 80C and rarely even see 70C, but I mod all my stuff pretty heavily. A 18 FET 4110 controller "Should" be able to do 100A battery and 180-200A phase. Never tried myself.

Maybe someone else can chime in who has pushed a 18 FET 4110 harder, I have more experience with the 4115 FETs.

Best thing I can do is warn you that when you get too greedy, it costs you. I have one popped EB212 4110 controller to prove that, did it playing with my 9C 2806 in a 20" wheel

Pick your voltage, look at the estimates of amp draw I provided based on wheel size and voltage and target enough battery amps to get you into BEMF so your amps start to drop. With a 29" wheel you probably don't want to run over 75V fully charged because it takes 48A just to maintain top speed on level ground and 105A on a 10% grade. On a 10% grade at top speed that's 7800W.

[hillzofvalp]

Helpful. I understand the FET matching issue. I will run moderate settings for now (60/120) and see how I like it. I really need to start thinking about a super high capacity pack for this rig (high energy density to fit everything where I want it). horsing around I'm probably only going to do 6-7 miles even with 700-750Wh. luckily most of my commuting is not super long.

And btw I'm running 66V. with the 2807 I was seeing 40mph on the flats with 55/100A setting on my 12FET 4410. I rarely need to maintain 35-40mph for long periods. my average CA speed is around 22
