Please post the pictures of your controllers building process. We want to see more than prices and plastic boxes.

What is the power densiest controller you got (Watts per cubic centimeters)?

Just so you know, this guy reverse engineers controllers and makes his own.
 
Hey, do you plan to make any smaller controllers?
I looked at your lineup and a 200A batt capable controller is way too big for ebike use.

I have no intentions to build a dragstrip-ready ebike 😅
Also i would like a smaller controller for the reduced size.

A C150 or C200 would be pretty desirable for the ebike crowd.

I'm betting the motorcycle users are happy with these though.

Great, a Chinese controller copied and rebuilt by a backyard Indian company, what could possibly go wrong.

You'd be surprised; India has been working on becoming a competitor to China for the last couple years.
Wouldn't judge this company so fast without any collective experience with them

Just so we're clear — 3Shul Motors is not a "backyard" operation, and our controllers aren't Chinese copies.

We design and manufacture everything 100% in-house. We supply motor controllers to the defence sector — including Australian defence companies. We build controllers for eVTOL, go-karts, and provide white-label solutions for one of the biggest dirt bike brands in the USA.

The units being sold in this thread are our scrapped rejects that were sold to scrap dealers for disposal. Someone picked them up and is trying to flip them here as "clearance" deals. That's the issue — not where we're from.

Sorry, we dont make controllers that small

So why you did not shred the units before this and for how much money you sold them?
 
This isn't making any sense. OP says "We're 3Shul Motors — we build high-performance motor controllers and motors. "
Now OP says "The units being sold in this thread are our scrapped rejects"

From what I've seen of people using these controllers, the build quality, hardware design, etc is good, better most of the Chinese crap but not perfect (maybe better though with newer versions). The real reason though why I wouldn't buy one is the poor support, which is whatever on a VESC that is vanilla VESC but unless something has changed these run a modified VESC firmware that has not been released so you can't update them without getting it from the manufacturer which is very hard to do due to poor support.

By all means correct me if I'm mistaken, is the firmware source available? If it still isn't then "Our controllers run on the VESC platform — fully open-source, VESC Tool compatible, no proprietary lock-in." isn't exactly true. VESC is fully open source, your VESC isn't which seems exactly like proprietary lock-in to me.

If you are supplying manufacturers then I can see why they probably don't mind this, you probably provide good support for them and tune their motors. But if I'm buying a VESC I'm going to have to tune it and if I'm stuck on an old version of VESC as I've seen happen with people using 3Shull controllers so I can't fix a problem and you won't give me the updated binary, source, hardware files, etc.

To be fair I understand you want to test firmware updates but that's not how open source works. And maybe you want to keep the firmware locked to prevent the Chinese from reverse engineering your hardware and using it. Although I don't know how effective that would actually be.

Also this all seems a bit weird, is 3Shul still run by hackey? I mean he started documenting the development of these controllers on this forum, like this weird corporate introduction post makes if feel like it's run by somebody else now.

I'm sure this is not the response so far you wanted but I think I've been pretty fair, complementing and criticizing from what I've seen and I'm hoping you can improve based on the feedback.

I was on the fence to request the *.c and *.h header files yesterday, but now that scianiac brought it up, here goes...

@3Shul Motors Pvt Ltd , this is a formal request for the *.c and *.h header files needed to compile the firmware binary.

I would be happy to submit a pull request to Benjamin Vedder's github, for the files to be included with all the other source code files so graciously provided by other controller manufacturers.

As an example, even Flipsky has recently started releasing the source for their controllers:
github.com

bldc/hwconf at master · vedderb/bldc

The VESC motor control firmware. Contribute to vedderb/bldc development by creating an account on GitHub.
github.com github.com

If you are not willing to release the source, can you at least give us good reason why, and be responsive to those needing an up to date binary?

Many of us are more than capable of compiling our own firmware, and I am getting to the point where I won't buy, or recommend controllers (Vesc based) where the source is not available.

Thanks!
Adam
 
On the contrary, many forums, groups, etc are fanatical about "their team", full of fanboys for companies regardless how crap they are. Very hard to break into those places. Meanwhile we only ask for facts, proof their brand is worth supporting and I think in general if you can at least meet us in the middle we will be very accommodating. I rather liked 3Shul controllers when they were new, but that changed over time when I saw real feedback and yet I can change again if there is evidence. At this point the ball is in their court, even if they respond saying why they won't release the firmware that will help them in my eyes more than saying nothing.

I suppose he mean the other guy selling 3shul controllers but without the name and slightly changed model numbers. Not in this thread, but in this subforum.

Well fair enough, if that's the case I stand corrected. But you can't blame me for being skeptical, I know many here want to go into big motors and plow new ground but all I seem to see is threads detailing problems, failures, and lack of manufacturer support. Perhaps it's just people pushing the envelope too far with this stuff, and because the industry is largely unregulated.

I really would love to have a CC1000 controller. But the fact they have ended all US based distributors, coupled with all the other factors have me looking at other options. From 3shul's own admission they stated the US distributors were ended due to a high number of returns/failures. I wish someone would simply provide a "VESC Brain" that could swap a automotive controller's logic. The "brain" part wouldn't be that expensive to produce/sell. And the "heavy lifting" part of the controller would be robust. And if something failed, just buy another unit from a salvage vehicle.
