Well done, otherwise.

If all I need to do is pay attention to spell-check then I think I'm doing OK.

Any comments on location for the document, or if it can be a WIKI with pictures and video embedded?

I am a newbie in the subject and I think it would be useful before a brief description of the reason for owning a programmable controller (I suppose that in order to use different battery pack, different voltages, different currents, different motors).
I also think it would be convenient to have a scheme that indicates all the external components and an explanation of each one (controller, relays, preload resistance, DC-DC converter or battery charger,etc ) and then start with Paul's contolador also with another scheme that indicates each of its parts .. controller unit , igbt's , converter encoder / resolver, interface to PC, igbt desaturator,etc ).

my humble opinion is that it would be ideal a WIKI with pictures and video embedded .

Regards !
Pablo

That is quite an undertaking for a single document. A group of related documents may be able to address such a broad topic.

If you were looking for this document, where would you expect to find it?

There could be a link in Paul's forums, but I don't think ECOMODDER would host the wiki. Is GITHUB a suitable open source repository? That certainly deals with version control, dealing with edits that may have SPAM sales stuff and the like

https://en.wikipedia.org/wiki/Compar...sting_services

OurProject.org looks like a good place to start. But it would be nice if someone who actually USES this service was to recommend it

When I figure out where to store it, I'll post a link here. I don't really expect others to submit a lot of content - the topic is technical and kinda dry reading. But who knows?

Any advantage to google cloud services? Over on diyelectric cars the forum has destroyed the archives due to new ownership and posters are retrieving data that way.

Hmm. Any idea what google's product would be called? Their cloud services offer a bunch of stuff ... one of them sounds like it stores documents .. but not a wiki sort of thing?

Hi everyone,

I've just put in an order for the AC board (along with a DC board as well for a future project). Wondering if anyone has successfully mated any HPEVS motor to the AC board? I'm considering to use the AC35 on an 800Kg city runner.

Cheers,
Bogdan

I have not read of one of Paul's AC controller's driving an HPEVS motor, but that doesn't mean it hasn't happened.

An AC35 should be a good match for an 800 kg vehicle. What gearbox are you using? A quick google search gave me a couple of vehicles actually called 'City runner' and a whole bunch that were described as city runners.

[BogdanT]

I was also just describing it as a city runner ) With the meaning that I won't be doing highway speeds with it.
The car is a Trabant 601. Gearbox and diff ratios below:
Diff: 3,947
1st gear: 4.08
2nd gear: 2.32
3rd gear: 1.52
4th gear: 1.103
Reverse gear: 3.83

Given a max speed of 45mph, the AC-35 might actually be overkill, but I can't seem to find a forklift motor that will fit the tiny bugger (transversal mount and huge wheel wells)

I'd like to push AC35 or AC50 beyond Curtis voltage range with this controller. Would it be possible to parallel IGBTs for 1000 phase amps? Even that 650A amps would do, like Curtis low voltage model is capable. 650A and some 200V to a single motor. Then double motors/controllers for real fun.

[without being an expert] Speaking of the AC-35, on the easy&safe side one could use 600V/800A IGBTs to push 650A (with proper cooling) at maybe 156V. Going to extreme, in theory, sharing the load per phase between 2 IGBTs is definitely possible (that's what the DC board does).
