I've been following info on these closely as they are about the only off the shelf system I can find for 96V that can push the phase amps I'm looking for at this price point without building something myself (ala BESC V2) But man the software problems people are having are just a turn off for...

It sure looks like 3 turns per, but.. maybe there is a fourth underneath there. Really hard to tell because the bundles are actually quite tight, which is good. I might be able to see more once I get the opposing side plate off- I can't quite get the magnet ring off yet, I need to build some...

Ah yes, thanks for that reminder- I had the scope readings but didn't know the # of magnets at the time... but, now I know they are 32 magnets... Spinning by hand is damn hard because these are so heavy and not much to grab ahold by, but I got there in the end. I don't have a vice here big...

Hi all, So I just got in a pair of QS205 single shaft hub motors for a project.. they are labelled as "72V 3000W" models but that is all the info I got on them.. after cracking them open they seem the be the V3 style and in good condition, but I have no idea on what the kv rating / "T" winding...

I've looked through everything I can find on Infineon's dev kits and such and cannot find anything for this specific type of hybridpack II. The other gate driver reference designs I have found are all for either the 'six pack' style (like what Axiom was designed for) - or, there is one dev kit...

That is super good to know, I was starting to wonder about voltage sensing. That makes sense that it isn't required during enabled running, only current. I have spent a bit of time going over the various control schemes, from how VESC works to the Texas Instruments InstaSpin... I haven't...

Oh I have all of that- 3 lab supplies, two scopes, 500k count meter, various STM boards here and there (will probably spin up something specific for this once I get close with the pinout). This is my first foray into motor control tech, my other electronics hobby is eurorack synthesizers, so...

Also of note... this sucker gets warm, just with the 12v and 5v powered it is pulling about 220mA from the 5V and 280mA from the 12V. Doesn't seem super high, but the driver IC's get warm, I am assuming because they are doing the flyback generation for the isolation transformers and so they are...

Yes! I was able to trace out the current sensor outputs to the main connector. Stuffing about 5 turns of wire thru the small gap it has under each sensor and then just abusing an old junk laptop charger with quick dead shorts on the wire produced about 20 amps apparent to the sensors, which was...

Hi all, long time listener first time caller. I recently acquired a Infineon Hybridpack 2 IGBT set and driver board directly pulled from a full motor controller/inverter for automotive applications. Specifically, I determined it is from a Chinese company that makes inverters for cars and...
