Instant Start 18 fet Infineon Boards are here...

I don't pedal either. I zip-tie the chain up off the sprockets just so it's doesn't clang around. I would need a front sprocket the size of a pizza to even be capable of pedaling at speed, and then I would loose my off-road clearance.

You need parts to fix your piglube? I know where a whole pile of H-piggy2 parts are sitting.

 

[methods]

Me need parts?

phhhhhht.

I can fix that Prelude with nothing but a roll of aluminum foil, some scotch tape, and about 30 hours.
I am the master :wink:

It is an electrical problem - caused by me - and the solution is to pull out everything I have done and return it to stock.
I intercepted no less than 20 - 30 wires and I tapped into 30 more.
There are remnants of an all inclusive remote start system I installed that operated the trunk, windows, lights, locks, ignition, etc.
The entire engine harness is twist-taped together after hacking it for an OBDI ECU
The rest of the harness has no less than 5 splices on every line from all the different sensors and gadgets I tried at different times.
To top it all off I am running a junkyard motor so... yea.

I will fix it
I will sell it
I will buy 100lbs of lipo

I am also selling my ENDYN built block / supercharger, my extra bikes, some high end RC gear, and a few other toys.
I decided that there is no way I am going lead on the car.
Lipo all the way.

I am going to be rolling the most powerful overrated golf cart in Northern California

Hey meth is that a H22 in that car? My brother and I build a turbo f22 and we would like to build a h22 head for it and make a hybrid. Let me know if you want to sell a head!

Hey Method

Can you give me the value of R46_1 ( resistor close to the Uc) on that 18 fets start immediate controller? I accidently destroid it.

i'm rebuilding the first crystalyte I had ( the one that have the missing Uc)

I'll check with Kenny... or maybe Geoff or Keywin.. for the Uc.. I think you dont have this.... IMPORTANT part spare?...

Who could have one 116A Uc ready to send to me?


Thanks

hi R46 is 10k ohm same value on the rest of the family.
good luck with the rest hope that helps.

I posted a schematic (plan) in the 'Mini Monster' thread for the 6 fet controller. The schematic for this 18 fet controller is the same, except for the parallel fets and the 12V power supply section. Even the fet driver circuit is the same. The 12V power supply is already well documented in this thread.

I've got some spray on military spec conformal coating. I was going to spray the inside of the case and the whole board with it once the build is complete but to achieve its full protection it needs to be cured at 200F for 2 hours. Does anyone think this will be safe to do with components already on the board?

 

[methods]

200F should be fine.
I am no expert on the subject, but that is really not that hot -> under 100C
The only thing I would be worried about would be the insulation on the pigtails.
cut a piece and heat it up to 220F to see what happens.
My guess is that they will get hot enough to rip/tear/cut/short but so long as you dont yank on the cables while they are hot it should be fine.

Someone else will surely chime in with a specification on a specific part showing that you will be exceeding its temperature rating but... You know how that goes.
What is documented and what parts will really do often have little to do with eachother.

I also bet that you could cure it at 150F no problem. Perhaps it wont meet is full rating but it will work just as good - and you can be confident that you will cause no other damage. 150F is absolutely reasonable.

I really like the idea of spray on conformal coating...
I have been brushing mine on.
I dont like the idea of what your house will smell like. Conformal coating stinks like hell while it cures.
Better not tell your wife what you are up to.

-methods

 

[Mike1]

The cure temp is stated as 95C. The caps say 85C on them so I think I may do it at 85C (185F) and just leave it a bit longer.
Do you think I need to mask off the inside of the case where the heatsink bar fits before spraying?

 

[Arlo1]

Got my kit today and the CA. Great packaging job meth and thanks again looks good. I just need to take care of a few other things then after I get back from camping this weekend I will start the build!

 

[methods]

Again, no expert but *yes*

You dont want any kind of insulator between the heatsink and the case.
I usually just conformal coat the board
Interesting idea to do the case too... I think I will take it for my own

-methods

P.S. Everyone - please remember: Discharge the main capacitors before assembling and disassembling the board from the housing. When assembled there is isolation between teh +5V buss and +V. During assembly/dis-assembly it is almost certain that you will short the two. Dont be a nOOB and waste a board

 

[Mike1]

I'll also file down the sharp edges at one end of the slot before coating, that seems to be where most of the abrasion is taking place during assembly.

 

[liveforphysics]

Conformal coating the inside of the case is a terrible idea from a thermal standpoint. And yes, as Methods recommended, coating the area you are trying to transfer heat through to the sink would be a critical mistake.

As an example guys, the coating turns 1w resistors into 1/2w resistors, and prevents board traces from heating the air around them directly to transfer heat. A fully coated board would definitely be more failure prone from heating. Coating the inside of the case would be a huge thermal bottle neck for all the parts on the board except the FETs, which are the only parts that don't have to rely on heating the air above them, then that air heating the case it contacts, and finally out into the air around it.

Full conformal coating = Circuit board heat rejection nightmare.

 

[HAL9000v2.0]

I plan to seal the case and fill it with Fluorinert.

 

[no mods]

Fluorinert...? thats what i brush my teeth with.

 

[lesdit]

Basic question, after chatting with Bob at astro again :

Does this 18 fet controller keep the timing the same for all rpms ?
If so, this is non optimal. The sensorless controllers which base the phase on detected back emf, actually
optimize the timing somewhat as a side effect of this method of commutation. This results in better
efficiency that fixed timing.
The software in the infineon could do timing based on rpm, but does it ?

 

[steveo]

Hey Methods,

Have you tried the timing advance features in the software? .. I wonder if they will enable a higher top end speed?

thanks
-steveo

 

[icecube57]

I think the timing is fixed for 95% of the throttle band. The last 5% you feel a jolt where it picks up speed like it has shifted into another gear. So i guess it could be on during WOT acceleration but if the MCU is smart it will kick in above a certain speed... in which it also takes into consideration the throttle position to decide to enable it or not.

Yes - 120 deg tim. inc. top spd

I am having troubles getting the programing software to work on my main computer I am about to try one of my laptops but if anyone else has info on how to get the files to work the help would be greatly apreatied! P.S. I was looking on pages 22&25 of this thread for the download so if there is another place let me know. I am a windows xp based system as well.

 

[Jeremy Harris]

Does the instant start Infineon allow timing adjustment?

I've checked the non-instant start controller and there is no timing variation at all with speed setting, all that going over 100% in the programming software does is allow a bit higher duty cycle for the PWM (100% in the software is really about 90% duty cycle).

Yeh thanks but it still seems not to work. I also folowed the instructions on page 25 of this thread. But I still get The warning "component 'ComDlg32.OCX' or one of it's dependencies not corectly registered: a file is missing or invalid" Then when I try to use the program you sent a link to to extract it it says...
"Command line option syntax error. Type command /? for Help" I will try the laptop once I get home from the shop. I may be missing a program since I rebooted the desktop a year ago.
