Vesc 4.10 "failed motor detection" in BLDC tool

Does the motor make any humming noises? I found with my 4.10 from enertion i had to re flash the firmware before it would work. I think it was pre programmed for the type r and wouldnt play with my sk3.

Unfortunately no humming noises or movements from the motor. Not even a measure of voltage from the phase wires.

How did you re flash the firmware?

Thanks a lot for your help. I re uploaded the FW and corrected all my settings and still no luck :frowning:

I guess there is something going wrong on the output side of the VESC then if you can read and load firmware ok.

Go over all the soldered wires to ensure everything is well soldered, double check motor wires to make sure all connections are good. no cold solder joints.

Not sure if it’s applicable in your case since you managed to ride it for a while before it happened, but one of my vescs had a shorted pin on one of the big chips by the motor leads, might want to check if that’s the case. Posted a pic of it in my build thread. Might be worth a shot.

I finally found some time to check out my vesc. I replaced motor wires and resoldered connections. visually inspected the board and everything looks normal. No signs of shorts or anything for that matter

still no luck with motor detection in bldc tool

Im getting the same error message, when I try to detect the motor is jerks once, then again 10 seconds later and it gives me this error. Im using the 4.10 VESC’s with the 2.3 BLDC, both have the blue and green lights on. The other motor is fine and its the exact same assembly.

Has this been resolved, if so how?

@jonathanngkh This is a symptom of a variety of things. What do you have going on, any fault codes?

@chaka I posted this on my own thread earlier at http://www.electric-skateboard.builders/t/diy-electric-penny-board-first-build/992/30

Hi guys, I made some progress today. Soldered the nyko kama nunchuk receiver to the jst connectors and they connect just fine. Soldered the vesc to the motor connectors too, and soldered leads for my zippy batteries.

But I think I fudged up my vesc, really hope not. I was having a lot of trouble with the BLDC, but eventually i got it connected. Motor detection wasn’t working, but then I realised that was because i had my receiver plugged in. So I unplugged it, rebooted and reconnected and ran motor detection.

VEEEEEEE the motor starts going, slows down just like in Vedder’s video, then VSH it starts up and chokes. Next thing I know, the VESC is no longer connected, and the LEDs on the VESC no longer light up, so I can’t connect it.

I had my space cell connected to the VESC, VESC connected to motor. Did it short? Is it fudged? Should I get a new one? If so, how do I prevent the same thing from happening?

So close, yet so far

Did you solve this problem yet ?

And now I find myself here…

@ckaka or any who know how used VESC TOOL not BLCD TOOL hi do you know anything about Vesc tool I need some help to program my Vesc it only works with Vesc tool not blcd,I copy some set set up on YouTube but my brake don’t work down hills image

your setup is incomplete… those boxes should be green

@Ebisane9 that’s what I am saying I look on YouTube to program my vesc so that’s why I am asking for help and who used the VESC Tool before.

If you have a 4.10 hardware, I DO NOT RECOMMEND using the new firmware, specially in FOC, it won’t damage your esc but it will do some false DRV error. If you want to use the newer firmware you need to add a 4,7uF cap in parallel to C18.

@JohnnyMeduse hi I have spoken to the supplier and they said the Vesc software don’t need updating,I just want to know how to program it so I can drive and when going down hill it brake
