    HESC V1 150v 600Amp VESC based motor controller

    Sorry, I was wrong then. I have only seen original VESC hardware schematics.

    HESC V1 150v 600Amp VESC based motor controller

    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...

    HESC V1 150v 600Amp VESC based motor controller

    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.

    HESC V1 150v 600Amp VESC based motor controller

    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.

    HESC V1 150v 600Amp VESC based motor controller

    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.

    HESC V1 150v 600Amp VESC based motor controller

    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...

    HESC V1 150v 600Amp VESC based motor controller

    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...

    electric trial bike

    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...

    Nucular electronics - complete kit for ev!

    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?

    Observed trials bike designing

    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...

    Nucular electronics - complete kit for ev!

    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?

    Can you tell d, q values for QS 138 70H? I can set them manually for now.

    Nucular electronics - complete kit for ev!

    24f v0.8.5 Not sure is it a bug or not, but after I do Motor LR auto-setup on my QS 138 70H the inductances d and q are still zero. And right after auto-setup the FOC mode runs very noisy at low RPM and the Trapezoidal mode does not run at all, the motor does not spin, only knocks. But if I turn...

    Sur-Ron - New Mid drive Bike

    Guys, anyone tried the Sur-ron version of the Nuc 24f controller on non Sur-ron bike? I have found the pinouts from another Sur-ron direct replacement controller (Sintech). If I connect Halls and Throttle to the 9PIN connector and Ignition (3rd pin) to the 8PIN connector, will it be enough to...

    Nanjing far driver controllers

    You can see there is no release delay under the load: https://streamable.com/3bwxfc If you hit the throttle at no load it will instantly overshoot over the max RPM and then any throttle input will be ignored until it falls under the max RPM. You can see the actual throttle on the dashboard screen.

    Nanjing far driver controllers

    It the same as I have posted earlier in this thread. I have only limited the max RPM and turned on motor braking. If Throttle rate is maxed out to 224 it is instant response. Also found out ECO throttle curve can be tuned by ECO coeff parameter. 8 - is closest to the linear (but still very...

    With Throttle rate maxed out, I did not feel any delay at all on my QS120. On throttle release it's instantly free wheeling with motor braking and recuperation turned off.

    Interesting, is it a new company? do you have a link? I would assume it does not have the standard trials 21"/18" wheels+tires, shock and fork, or 42kg would not be possible.

    Nanjing far driver controllers

    Yes, it is with no load or in low traction like mud or snow. If the wheel sleeps it'll spin like a mad dog. Today I have tested it on snow, it is hell crazy comparing to the old Kelly on the same current settings. Low RPM, Mid RPM params should provide limiting points as I was told, but it...

    Nanjing far driver controllers

    ECO is slightly better, Sport is even worse as expected. I believe it is the speed loop issue, throttle curve will not solve it. ~2000 no load RPM on 1.5% throttle is insane. I am in contact with the engineer through aliexpress seller i have bought the controller from. All the things he...

    Considering what they replied when I asked for torque curves I will not expect much.

    Nanjing far driver controllers

    I've tested 72530 on my trials bike with the QS120 motor. It works well with the same parameters I posted earlier for the QS138. At a first glance it looks more effective than my old Kelly, and the throttle response is very fast. The only problem I cannot figure out is the throttle position...
