Obviously, hardware protection means VESC hardware designs, not VESC software. Prove me wrong, but I have not seen a single VESC design with hardware OC protection. It won't protect against everything, but I have seen industrial controllers that can catch phase shorts without a damage.
That is...
VESC does not have true high speed hardware OC protection. Only software control loop one, witch is at least half or equal PWM frequency reaction time.
Badly tuned VESC or bad hardware design can blow-up if the connected motor winding current is capable to rise quick enough to escape mosfets SOA.
I have searched that FB group/pile regularly. Unfortunately still nothing on any of Shul ESCs even remotely close to full spec.
Those kawasaki log is just 250A max PhA which is not even half the spec.
Very light load from independent party.
I am mostly interested in CL1000 and CL1400. At such high currents lots can go wrong.
At least I need more info before spending $1K on the thing without a warranty.
Thanks, I have seen that. It is not independent and it's least powerful CL300. Most problems arise on high currents.
Can anyone open the cover and make a photo of the power and logic board with part numbers visible?
Or just write down the markings on the mosfets and mosfet drivers, so I can...
Did anyone independent torture any this controllers to full VA specs? All I have seen since are no load or very light load which tells nothing about the controller design quality.
Can you read the microcontroller markings or it is brushed off?
If it is an ST or one of it's clones, it can be VESCed :flame:
Even if it's flash programming is blocked, it can be replaced with a fresh one with the same package real easy.
EDIT: It is LQFP48 and VESC uses STM32F4 in LQFP64...
It is a similar chromoly skeleton design to Vertigo: 4 tubes + 2 crossbeams welded to the headtube.
I am more concerned they did not publish any power/torque specs yet. It is 15kg lighter than EM with the same battery capacity.
Also does it have a flywheel? Clutch without a flywheel is a waste...
Latest firmware solved my issues with LR measurement on QS138 70H
Vasili, since you are very familiar with QS138 70H, what extra settings do you recommend to make after auto setup + LR for best performance with Nuc24f?
Picked up barely used Vertigo R2 300 in october. 68 kilos and 26Kw 52Nm @crank, what a petrol beast!
By my calculations this translates to 1800Nm wheel @1st gear minus 3-4% for the gearbox and the chain drive losses.
Clutch drops on the 2nd and 3rd feels brutal even at mid RPM.
Injector mapping...
No, it is the same.
Looks like DCR and Flux linkage measurements are correct: 4-5 mOhm, ~0.02 Wb?
Only inductance fail.
PITMIX, if I am not mistaken, you have Nuc + QS138 too.
Can you share your measurements of d,q, and Flux linkage?
