Teaser Speed Controller

This looks very Burly Gwhy,
I am anxious to see your results. Are you going to post up the artwork for us home hackers?
(i still need to assemble my JH simple controller LOL) but this does look fantastic.

Thanks Thud.

I hoping to have some results on how it really performs mid next week. The artwork will be posted up as soon as Im happy with it ( but so far so good ) the pcb's are done in such a way that it has minimum drilling ( which is something I have always hated about making pcb's) it is exactly the same setup (components) as the JH simple controller its just a different layout. Once I have tested the power board stage and make sure that it still performs when the boards are stacked ( for more output power ) I will be adding a few functions to the controller stage ( i.e battery voltage monitoring, some throttle mapping and a few saftey interlocks ) I may need to look into phase current limiting ( I have thought of a way of implementing it using minimum alterations but dont want to jump in just yet ). My requirements are to have 3 powerboards stacked ( 300A ) output. I have no plans to have regen on this controller but if this one works out ok I may make a new front end for it.
 
Regen would be great as it really saves on disc pads and is safer when used in conjunction with a disc brake.

CA connection would be great but not essential I suppose but even if it could be used just to show watts/volts and AH used would be great.

Some sort of speed switch for switching to legal mode maybe when needed.

I dont own a CA so I dont really know how they are connected to a controller but I think it could be installed pretty easy ( :? ),
Also a speed switch will be easy to implement ( It could be incorporated with the throttle mapping that I need ).
The next controller chip in the series will do motor braking ( not regen ) so this would be a very easy upgrade just by replacing the controller board.
 
Amasing work mate, cant wait to see how it works out! and you wern't kidding when you said tiny!!!! :shock: :shock:

regen would be good, as others say its really useful on long descents, saves the breaks for when they're really needed. And ca would be good, if you can mate, since I (will be soon) use the 'current' throttle option they have. has heaps of other usefull stuff too...
 
Great stuff GWhy! Capability to plug in CA
Would be fantastic, wouldn't bother with Regen
myself, engine braking for the fellas building race bikes would be a bonus!

All the best GWhy

CA is worth it for the current throttling alone.....if I ever get around to setting it up.

Any idea on price for the these controllers?

Not sure on total pricing yet. But the price for a set of 3 pcb's( only ) will be around £30 - £40, for each additional power pcb will be around £10 -£15 this is based on me making them as I have looked into having them made and it works out very expensive as 2 of the boards are double sided and they are quite long ( unless some one can point me to a place that I can get them made cheaper ).

sorry mate I dont understand the math, does it mean about 30-40 for each set of 6 fets? seems too good to be true, witch makes me think im missing something...

ah durrrrrr. whats the normal cost? im guessing less than this, so we can expect these to top 250 or more?

I have totted up the cost of all the boards and components including 6 fets and other hardware, what I paid for these items it all comes to around £100, I did not shop around for the cheapest suppliers, It takes around 3-4 hours to assemble from start to finish so I expect you maybe looking at around £180 to £200 uk pounds this will be much cheaper if I can get the parts cheaper. The spec would be 120A cont for the 6 fet .

:shock: :shock: :shock: :shock:
im in. particually if you can get ca and even regen too!
 
WOW Gwhy!! Put me on the list!! I may need to get a bigger motor!

quick! get in on the 540x buy! its half the reason im interested in these monsters!
 
Lol, I was thinking for my RC drive! I figure I could run lower volts and a bit higher amps than the controller I have can do... lol!

What the hell does Whiplash want with a boat anchor weight motor on the ass of his bike
when he's building reduction drives for RC motors that run through the bike's 20 plus gears :-S

im asking myself the same thing! mainly its becasue frocs are simple, and 'reliable' :p .
soon as HK get around to restocking some bigger motors ill be going the rc route too! :twisted: either that or ill start looking to brushed motors :shock:
 
That's awesome! If it has lots of CAPS on the PCB to make it pretty much bulletproof even with extremely-low-inductivitiness motors, that's awesome!
 
Freakin badass Gwhy! Too bad all your prices are in british pounds though. :x

It's funny how AJ is all nice and encouraging when he wants something from you. :lol: When did you swtich over to the darkside AJ? I sense ( get it :roll: ) a disturbance in the force.

What?! where aren't encouraging etard? (Hyena excluded) ?
And how do you figure i have switched? i have always had a
non-frock setup...both sensored and uncensored, would still be using the
12fet if i had configured the bike originally for 9 packs not 8 so i could
run 66v setup, on 44v sensored 12fet is poo...

And FYI etard, I like anyone else wanting a controller will pay for it when/if made available.

update,
I have bench tested the controller using the 6.5kw turnigy motor in its current state from zero to WOT loaded to around 20A and I also ran with a cont load of 10A for 15mins (no heat sink) while I was scoping all the signal. All the signals at this power level looks very good indeed, startup of the motor is very smooth and slow running is also very good. After running for 15mins with no heat sink @half throttle @ 10A the fets barely got warm so this is another good sign :) . The next step is to fit the heat sink and fit into the box so I can put it on one of my bikes, so basically all the same results that JH was getting with his controller 8) . I'm aiming for mid next week to have it up and running on a bike so I can field test it as a 6fet controller running at 120A, both of my bikes have the 3250w motors at the moment but if the controller behaves with my small motors I will swap it out for the bigger one, I have also ordered some more fets to make a bolt on upgrade (the controller with then have a 200-240A limit :twisted: ).
 
I was just blowing wind up your frock there AJ, I know you are a fan of only quality components, that's why we all value your opinion.

Gwhy,
You have taken Jeremy's last gift to us and run with it, that is to be commended. This controller should be manufactured and sold with an official ES emblem of sorts and hand signed by the man himself and then trials tested immediately to failure along with quality video of Kevin doing some sick trials manuevers over logs and rocks. Now that, I would be willing to pay for! :mrgreen:

Yes I have :mrgreen: I thought what was the point of re-inventing I'm just putting my own slant on it and maybe a few extra's. :lol: I dont know about me doing some slick trials manuevers ( Im am getting on a bit now mind :shock: ) But I know a guy that can :wink: All I can do these days is fall off in style :mrgreen:
