New Puma Controller Lid Off

[deecanio]

hey jozzer,

at least you got a spin - im trying to wire up now and having no luck at all.
i've tried every combo of phase, nothing
i've checked the halls and their colour for colour , continuity test back to the controller board checks out ok?
looking at the throttle i have on the controller side, red ,black,white on the throttle side i have red,green,yellow?
not sure what to try now i haven't had a murmur from the motor at all ?


cheers

[Jozzer]

Err, not sure, cos I left the bike at work, but I think the black from troller should go to the yellow, white to green. It would make sense the throttle was the culprit, since you would get something however you connected phase.

At least yours might still work!!

BTW, this is Knoxies test controller right?

yeh this is the one knoxie was running and i think it was all straight connections apart from phase as his is front and mine is rear.
i've tried all combos on the phase all with absolutely nothing from the motor, the throttle is black to yellow and white to green and i dont remember paul mentioning anything was different apart from the phase.
ALTHOUGH...... im testing on the stamped puma rear as are you,i think.
knoxie was testing on the new pumas, could be totally different as far as halls or phase are concerned?
i suppose we will find out if your second test works - not sure i like the sound of the throttle being on even in the closed position as im testing the wheel in the bike.





cheers

[Jozzer]

Swap the 2 throttle connections that ARN'T the same colour...I dont think anything else would stop it at least trying to run.
oh...and always test first with the wheel up! And rev it out to check the no load amps arnt too high too..

 

[deecanio]

i could give it a try - are you sure i wont burn out the throttle is i swap the cables?
i dont know dick about it really, maybe i'll hold on till knoxie gives us the the low down of how he set up?
just dont want to blow anything as ive waited so long to test.

As long as the red is right theres no danger, and even that might not matter. Thing is, Knoxie had the same colour Phase wires and halls...if its not the throttle then something is BrOkE. If you want to wait, then tomorrow I will be testing the 72v controller with the New Puma motor (brother of Knoxies). I'll report back on all connections then...
One thing, I understand he had to cut the blue wire that leads out of the controller and then back in (or from your standpoint, 2 blue wires coming out that once were connected). These are for reverse, but even if that needed connecting you'd get something! (you'd hear the motor spinning backwards, if this happens then try connecting the 2 blue wires :lol: )

 

[deecanio]

Hi Jozzer,

yeh i'll hang on and see what results you get, i'm not sure what the hell that looped blue wire is but it is looped at the moment, can't see anywhere that knoxie tampered/fixed that, although there is a couple of other cables thin like the blue that are grey and yellow? i thought these might be brake inhibit ?
At the moment these are not connected so i wonder if thats why im getting nothing, maybe, i dont know if the brakes work by closed circuit and when you brake it goes open circuit? maybe paul just shorted them to make contact, i removed the plug from them and then just taped them for now.
Anyway i'm not sure so i'll hang on and then press on once we (read you and knoxie) have it figured out - i'm too close to running 72 to risk breaking anything at the moment!! hehehe

good luck today!!!


cheers

[Jozzer]

Yeha, the blue is for reverse, and the odd 2 wires are brake and needn't be touched. I'm off to the workshop shortly...

 

[deecanio]

ok good luck steve, post up later and we'll see whats going on.

cheers

[Jozzer]

heeh..so much for the luck...i just sliced my hand whilst trying to strip the wire ends of the female phase plug...the sharp metal connector flew out and passed between thumb and forefinger, thereby ending my chances of doing anything dexterous for the day (including my gig tonight...me looks for replacement saxist).
its a pretty deep cut, and I got no first aid kit here yet....so back home to nurse my wounds!
Sorry Deec...i'll be back on it tomorrow morning I hope

OK, after deciding I was being a wimp, and having nothing better to do today, I carried on in a dazzling display of onehanded soldering, and finnaly got the wheel going mounted on the bench, using a regulated PSU (just in case).
Seems to work fine, no sign of the troubles I had with the 48v controller...
Throttle wiring is
Motor red to red,
motor yellow to black,
and motor green to white.
phase and halls are colour to colour.
Seems very smooth, no vibration or jerkiness (there has been in the past with some other controllers).
Ran it up at 70v too (max on my PSU), all good.
The one thing that perhaps hasn't been done yet by me OR knoxie, is to try this controller on the older revisions of the motor, and I havn't tried this new revision motor with an x'lyte motor yet, so we don't know for sure if they have changed the phase colours on the motorside or the controller side!
Paul, have you tried the new motor with an x'lyte troller yet? (save me some work if you have).

Before I can run it on the road I need to sort batteries in the bike, so maybe late tomorrow for a road test...

What is the dc current at 70V from the PSU?

 

[Jozzer]

Ita a very old and heavy Farnell TSV70 MK2, 35v10A or 70v5A.
Though its very big for its power, I reckon it may well live forever. Got it very cheap from ebay a while back.
Why do you ask?

Like to know what is the current taken by the Puma motor at 70V running at no-load when fed from the PSU when you said it ran smoothly.

hi mate,

hehehe i'd have been off home muttering f****** bike
yes i think that i have trouble/wrong connections for exactly that reason - the new controller in any guise hasn't been used with old stamped puma, a bit of a pain as i think i'll have to ask mark to get in touch with the factory maybe and find out if there compatible.
longer term i will get the 320 and a higher amp controller but i had hoped i could ride the old puma on this controller until then, oh well.
lets see what if paul knows anything to try for me and at least you can ride the new motor and controller
in any case i'm sure it'll be sorted and i do still have to make my seat by the time i've done that and finished the cages all will be clear.

cheers for testing,

[Jozzer]

the7, its still set up on the bench at work, i'll give it a run tommorow and let you know.

Deec, Actually, I remember when knoxie first got this controller he had it mounted on the bike with the x'lyte controller too...if there are any differences he might have mentioned it in that thread. If the old controller works with the new motor, or visa versa, then they are compatible. Even if they wern't, you would still get SOMETHING I think.
Can you handle a multimeter? Check power into the controller just in case (open it and carefully probe the power wires at the PCB end), and check you have 5v on the red wire of the throttle out too.
Have you checked everything (throttle/motor) still works with your old controller? (which version do you have btw?)
theres something fishy there, its a little strange that it doesn't want to do anything at all.

 

[deecanio]

i dont think paul checked the xlyte with a stamped puma though and the bmx motor isnt the same.
it could be that it's something silly,i'm not great but i can check power at the board and the throttle - maybe i'll get on those tomorrow, haven't checked the xlyte either as it has different connectors now (din on the halls).i have the xlyte 36-72v 35a?
i will do the checks and post up, im not sure when though as i have loads on 2moro and tuesday might not get any bike time this week as i'm having a new bathroom in thats why i was miffed i didn't get a ride this weekend hehehe.
i'll try and check 2 moro night and see whats wrong.


cheers

[Jozzer]

Weather forecast looks good for the week, might be the last chance before "winter". :lol:

 

[deecanio]

yeh was hoping to have it running before the cold really starts :lol:
i'll have another look tonight and give paul a bell see what he thinks.
I'll post up later and see where we are.


Cheers

[Jozzer]

For the7, no load @ 50v=2A, at 70v 2.4A..

Good luck Deecanio! Your about the most patient ebiker I know, you've been at this for years :lol:

 

[deecanio]

hehehehe i know seems like i've been trying to get to 72v forever :lol:
nearly there mate and the bike is looking good, i'll have a little play with it tonight and see if i can get anything to run, just hoping to get a ride before the winter kicks in but i can see that the bike will be living in my spare room until next spring hope the mrs doesn't want the space !!!!
i'll give knoxie a ring and see if he can help us out although i dont think he has a stamped pums period?


Cheers

[Jozzer]

What do you man stamped? The ones with the numbers pressed into the side? Or with a sticker saying 250w etc between the flanges? I think I had one of most of the prototypes, and all had the same wiring untill now (and maybe even now)

 

[deecanio]

it has the numbers in the side and the 250w sticker between the flanges ?
i know this as the stamped puma as it has a large BMC stamped on the side too?
check out my thread for a good picture?
i think you have this motor too - but you haven'y run a new controller yet?


cheers

[Jozzer]

Idd, I don't fancy chopping all the wiring up on 2 working bikes to try it! (sorry:)

The new controller is testing out fine, smooth and powerfull. The new motor is very nice, (260RPM version). VERY torquey in a 20" wheel! 48v gives around 20mph.
Over the weekend i'll beef up the brakes on the bike so I dare rev it out at 72v...feels too scary ATM (bit of a silly chopper, I should have tried it in a KMX!)

Motors and controller on order now, Mark should be selling and shipping before christmas...

Ciao all...

[Microbatman]

Shipping them before Xmas
Sounds great.
Who will be distributing them in the US?
