Cmon mate, Its only 100vdc, barely tickles :lol:

It's not the 100vdc that's the issue, it's pumping 240vac into it :lol:
But yes, a nice gift for a theif. A remote dead mans switch of sorts

Even an IEC jack wired exclusively to the frame and labeled "Charge port" isn't a bad security feature

LOL

On a different note I just can't seem to make the XPD software work :?
I don't know if I have an EB 2 or EB3 controller but its a pretty recent purchase from Lyen so probably EB3 ?
Everytime I try to save my profile with v 0.3.2 I just get "Failed to save profile 18 FET Default Sensorless Preset:
[Errno 13] Permission denied" ...... tried with 2 computers now, same result.
When I try with v 0.2.1 I can save profiles but get "upload failed invalid reply byte fd" when I try to flash the controller.....

spewin'

any idea's, anyone ? Please

 

[oldhaq]

It'll be v3.

I couldnt get xpd to flash bretts v3 controller either

Try to flash with keywins eb3 flasher after (re)installing drivers. I've sent what u need to your email.

Thanks rob, that did it alright, flashed the controller and took it for a late night test ride up and down the street, awesome, it really gets going now, I'm rapt

What changes did you end up making to your controller config?

 

[thewmatusmoloki]

I raised the phase current from 80a to 150a and the rated current from 40a to 67a and the block time setting down to .8 seconds.

I noticed on the CA that the max amp draw was only 39a, these 18 fet controllers should be good for 65 or so amps so I dialed it up.

Pretty exilarating ride now, even though the rear wheel is way out behind me, I still have to lean forward to keep the front wheel down. These old school 8x8 1000 watt golden motors (purchased in 2008) are quite heavy duty compared to what they seem to sell nowadays, not sure if anyone still makes 8x8 wind motors.(more copper fill, harder to fit in,more expensive to make) anymore. + the stator and magnet width is 31.5mm compared to most direct drive motors being 28mm now such as 9c, mxus, Conhis and currently sold DD goldens.

Is that the "Real highway" 18fet lyen model? That's what I ended up going with. I just realised I forgot to order the USB interface thingy, oops.

yep, that the one, it's got the 4115 fets. You can borrow my programming lead if you like....

Thanks for the offer. I'll likely order one, since I like being able to mess around with settings. I think it's already setup for 100V and 45A, so that'll be good to start. I'm not sure how much current the HT3525 can take before becoming saturated/over-heating. I'd assume 60 is about the limit.

Cheers

 

[thewmatusmoloki]

Wow, is that actually a freewheel or a fixed cog ? Looks too small to house freewheeling mechanism.

Amazingly, it's actually a freewheel albeit, fairly hard to turn, prolly a cheap shitty freewheel really ..... not to worry mate, it'll be easy to abstain from using it 8)

I'm not sure how much current the HT3525 can take before becoming saturated/over-heating. I'd assume 60 is about the limit.

Have had a bit of a play with those motors actually, not bad, but the wires and generic hall sensors seem to melt pretty easily within the hub.
I totally recommend drilling some vent holes in your side covers straight away to avoid the "oven effect" when you stop.

Meh, 60 amps rated, it all depends on how much you stress the engine out in short bursts in the end, it'll take a lot more than 60a in an emergency situation or for a short burst, but they won't handle 60a continuously.

Trouble is, once you've tasted the high amp power.... it's too hard to resist

I'm a bit unclear regarding the disassembly of the 3525. Do I really need 3-leg jaw puller tool just to get a side off and drill some holes? Can I just unscrew the disc side and the plate comes off? The screws are in crazy tight and made of cheap metal, so I don't want to molest them if it's not going to work anyhow

The puller's are handy but in all these years I've personally never owned or used one.
To disassemble a direct drive hub motor : first, remove all the axle paraphernalia (nuts, washers, torque arms) on both sides then take off the cover on the wire side by unscrewing the bolts then hold the wheel by the tyre with the non-wire side still bolted up and facing downwards, find a block of timber and holding the motor firmly smack the axle on the non wire side into the piece of timber, you can screw the nut on a couple of turns to protect the end of the axle if you like, but you'll have to take it off to get the stator out. The first couple of hits usually loosens the cover that's facing you (the one with the bolts removed) at this stage remove this cover if possible. Another hit usually pops the stator 1/2 to 3/4 of the way out so you can grab it and pull it out from there. Be careful as it's a powerful magnetic field and people have lost fingertips You can then remove the bolts on the non wire side and remove that cover from the magnet ring.

One of the problems with those particular motors from crystalite is that they glue the bolts in with some kind of epoxy (dickheads)
And if I remember correctly they sometimes use Phillips head bolts instead of Allen head bolts (another stupid idea), so you will probably need an impact driver to get them out.

Hope this helps, it's quite difficult to explain, but if you see someone do it , just once, it all becomes clear.

Good luck,

Matt

Make sure you remove both covers before drilling, you sure don't want to get metal shavings all over the neo magnets, that'd be a right bastard to clean up I would think.......

Actually, that explanation completely clears it up, thanks!

Yeah, mine are phillips-head screws held in with something. Luckily, I discovered you need a very specific sized bit to un-do them without stripping the heads. It's fine once you've got it, but I went through more than 10 other bits that would've easily trashed them. They're more of a flat + shape than standard phillips screws.

As the name of this thread suggests, I thought I might add some better suspension ..Went AIR with this new DNM shock off ebay, couldn't resist the sub 100 price, it works really well keeping the rear end firm for decent handling but dissolving the bumps on a cushion of air. 40mm travel.

[thewmatusmoloki]

took it for a rip 2 nights ago and burned out a hall sensor, not surprising really as I was giving it some stick.
Fixed now but made me think that maybe I should move forward with some kind of 21st century type frock motor.

I was unsuccessful in my attempts to purchase a cromotor in OZ, but not to worry, I don't give up that easy.

Got one of these motors coming from China ...
http://www.aliexpress.com/item/205-spoke-motor-3000w-Electric-Bicycle-Scooter-Motor-BLDC-hub-motor-Enhanced-Edition/1329786841.html

interesting that it has the x5 type stator inner and the 50mm cromotor type mags, dual halls. It'll likely need a wiring upgrade.... thought I'd give it a go.
Not sure how I'm going to deal with 190mm dropout width, but I'll think of something :wink: The one I ordered is the right hand motor in the first pic... View attachment 5

I'll keep youse updated

Ganbei,

Chester, my Golden Retriever/ Labrador is dead. I had to have him put down an hour ago. He died in my arms.

He developed problems with his rear legs over the weekend and I rushed him to the emergency vet this morning after staying up all night with him, only to be told that his spinal nervous system had shut down and there was less than a 1% chance of survival even with expensive surgery.

I've never been married (not gay!), got no kids and as the big 50 draws closer I don't have many friends anymore, so he was my best mate, don't know what to do to ease this pain. Thought I might just type at this screen for awhile.

I got Chester from the rspca 7 years ago, they estimated that he was about 7 at the time.
Somebody had fed him up to 66kgs then driven him across town and kicked him out of the car with no I.D.
Not sure how anyone could do that to a dog.
After years of walks and good diet he was 36kgs when he died.
I just hope that I made the last half of his life more comfortable and nicer......

Lots of dog lovers on this forum, just wanted to say treat them like you love them all the time, every day.... I did.....

 

[trevc2]

Damn it... I remember seeing pics of him enjoying the trailer attached to your bike. Seemed like a great dog. Really sorry for your loss.

 

[thewmatusmoloki]

Hey thanks Trev, he sure did love going for rides in that trailer !!

He was one of the gentlest and kindest souls I ever met, and will never be forgotten....

Good to see that you got the demo9 going.
Looks awesome man !

Matt

 

[trevc2]

Can't believe they got him to 66kg (the same as me!), that takes some effort. Glad he found someone better.

Yep, about 250k's on it now. 1 pack (4x8ah) can go up to 38k's, discharging to 3.6V ish, and that's without being gentle. I've went after some of the steepest roads I can find around here, no issue with overheating unless you repeatedly WOT them I always keep it under 100C in extreme cases, but under 65C 95% of the time.

I actually have a "secret" spot where I can do speed runs on a long stretch without any danger of pedestrians or cars pulling out. It's fairly hidden from view too. I've reached nearly 75kph on a full charge. Of course, I never go that fast anywhere else since I'm only wearing shorts and a t-shirt, plus it would attract too much attention. 40 ish is a great speed for not getting noticed.

Entire bike weight is 35KG including battery, some bike tools etc. That's not too bad. Cromotor looks awesome, but it would end up a lot heavier especially in the rear.

I'll likely hide the 18fet and wiring up behind the front fork mount to increase stealthiness and shift a bit more weight up front.

Great work with the bike, it looks like a nice plush ride.
I'm sad for your loss, Chester's a lovely looking dog, good on you for making his life so much better.
Cheers,
Matt.

Thank you.
That means a lot to me actually because I have a great deal of respect for your builds.

Many thanks to voicecoils at Glow Worm Bikes in Marrickville for his excellent work in putting together my cromotor and fancy gold rim.
Unfortunately whilst trying to find the right phase and hall color connections, two of the phase wires touched and my lyen 4115 controller blew up fairly spectacularly Meh, shit happens .... Just ordered a new one thru EM3ev
Here's a pic of the v2 cromotor laced in with a Pirelli ML75 tyre on.
In the meantime I need to get my ebike fix from somewhere so threw together the old headway and a spare golden motor on the last of the surf chopper frames, got 5 of theses frames for $300 about 8 years ago, this is the last one, I'll be changing the rear wheel for a 20" rim on this as soon as I get some more spokes

 

[trevc2]

Oh wow, that Cro build looks awesome. Nice tyre too

How much power are you going to push through it? No vents?

 

[thewmatusmoloki]

Gday Trev, just haven't got around to the vent holes yet but they are coming. According to EM3ev, the max amps safe amps for these controllers is 50 amps so I'll probably just go with that.

BTW does anyone know the correct phase and hall colour connections for an Infineon 18 fet to a V2 cromotor ?
I tried searching but came up with nothing, thought It'd be an easy search actually, but nay. There's just got to be a ton of members out there running this combination by now I would have thought.

Any help would be greatly appreciated....

Cheers
