VESC Settings help, sensored motor

I have a 5095 motor and a FSESC 4.12 50A Based on VESC® 4.12. previously it worked fine but suddenly it has knock issues and sometimes it won’t turn unless you spin it a little, i tried reprogamming it with VESC tool now it won’t turn completely (see video https://streamable.com/w9t55 ).

It seems like a sensor problem because it has hall sensor and it is connected but once i do the auto detect it says sensorless.

Thanks for the help in advance!

I would check all the sensor wires using a voltmeter, just open the can and check using the piping tester, if it makes noise, it means it has current going through, if it is not making noise, then you have a cut wire to replace…Before doing that, check the JHT connector , male and female, sometimes the pins move or get cut in the joints…hope it helps…

Also, you could ride sensorsless, do detection in BDLC, and just use it like that…

i will try sensorless first, i just need to reprogram it without the sensor wire connected right?

I have always run sensorless to avoid issues like this. Pushing a bit to start doesn’t bother me

The VESC ™️ Tool reports everything not VESC 6 as sensorless, you have to manually set it to FOC/Hall Sensors.

Cheeky - thanks for the giggle

am not really familiar with setting the motor manually, can you help me with what i need to setup

i tried the FOC wizard without the sensor wire connected it detects fine but when i try to run it with remote the result is the same as the video.

when i try to set it with BLDC it says detection failed

It’s almost impossible to walk someone through the VESC tool setup without at least video. I’d suggest trying, this. It walks you through the entire process.

FOC+hall sensors is the way to go! Couple things could be wrong.

#1 use usb and a PC. Phone app is impossible. Make sure you run the FOC settings sense procedure, test run it in FOC mode with no hall sensors, then run the hall sensors sense. The hall sensor sense is important for VESC to know where it is when starting.

If FOC doesnt run with board upside down, and with you on it with a kickstart, theres a vesc issue. If the hall setting sense doesnt work, or if it doesnt run after that, it’s probably the hall sensors.

Could be hall sense wiring.

i’m doing it on my PC, i ran it with hall sensors and without. without the motors run normally upon detection but once i do the fwd/rev setting and remote acceleration it does the video.
with hall sensors it does not spin at all and does the video.

will have the wires opened and checked. if that did not work will need help with Arc (i bought it from them)

Thanks!

How do you mean the phone app is impossible? I have used it with great success.

:rofl: it’s just complicated compared with the pc app. Once you know the menu flow it’s super effective

Did you run the hall sensor sense?

not yet, i will check the wires first i feel like it’s a hardware problem. will do it on the weekend

Need to run the hall sensor sense for the vesc to know how the order of the hall sensors corresponds to the order of the phase windings.

i tried running the motor wizard again and this is the results.


this is the result with the sensor wire attached. the motors rotated but still have glitches, and when i tried running it normally it won’t move.


this is the result with the sensor wire not attached. the motor did not spin at all.

any help will be greatly appreciated!
