Beginner Question Thread! 2023 Edition

There is a gap in the noise it makes for about 40-60% of the rotation, I was spinning the wheel since it’s easier to record the noise when it’s moving faster.

I’d be a bit worried about it causing more damage if it was left as it is; if a piece of hard dirt or metal got caught in whatever is grinding and gouged out a bigger lip or something. Though it might just grind and clear itself

Oddly enough, it seems to have fixed itself?
I tried yesterday to get a video that better shows the spot in the rotation of the motor that makes noise but for some reason after leaving it alone for a few hours it seems to have gone away…
I’m hesitant to trust it’ll stay like that, but I’m gonna call it luck for now :sweat_smile:

I have a Tynee Mini 3. I liked being lower to the ground, so I removed the riser pads, got wheel bite, and broke my arm. Does anyone know of any wider CNC trucks that I can use that are wider so I can keep the riser pads off? I use Mad Wheelz 105 v2

I got a pair of @moon gear drives I want to mount with mbs wheels but the instructions are nowhere to be seen. Does someone still got the PDF?

This?

I loaded Vesctool onto a computer not built in 2008, and have established a solid connection, and am getting acquainted with it.

I’m getting results on test rides, that are not great.

Trial and error with FOC then BLDC are less than ideal, and ridiculously noisy on both.

Im wondering if I am setting the motor poles correctly on detection

I saw one hub motor yt vesc video that says leave it at 14, but my motor documentation says:

Motor poles, what should I set them to?

Pole pairs has always worked as magnets divided by 2 for me. What are the symptoms of not working well? I can’t remember if your motors have sensors or not, if they do foc has always been good to me

Look closely at the gap between between your motor cans and their bases. I’m guessing the little brass spacers on the motor shaft have worn down and the slack they create causes that noise when your motors slow down. You need to remove the circlip off the shaft and replace the brass washers. Or at least that’s my guess…

They do have sensors.

They are super noisy, compared to the Puaida/Lingyi esc. stuttery.

Is it the high pitched noises at startup or is it the resonance at higher speed noises?

low speed sounds like something is grinding stuttering within.

Higher speed is the electric motor whirring that sounds a bit like belt drive

Correct me if I’m wrong but you have it set up with VSS correct?

I’ve only tried foc and bldc so far

How are you setting up your sensors during motor detection?

Sensored, HFI, VSS, Sensorless…

I haven’t had coffee yet.
Im thinking as clearly as this photo of the last detection when one motor was 10 amps higher than all previous detections

Yeah something is off about this detection. One motor detected with way lower resistance

ill start over in a bit

I can better walk you through the vesc tool setup if you’d like. Discourse has a new chat feature too

I got a few things to do before i can hook skate to desktop, but id love to be able to ask questions during.
