So just a quick side question.
Which VESC Switching Frequency do you guys ride / prefer ?
I currently ride 34000 hz on my Longboard.
The higher the frequency the less of the usual BLDC Noise you will get - however it will be harder for the VESC to switch so fast - even though I did the Capacitor Mod I still don’t feel comfortable going too high.
I wonder if changing the frequency will have an effect on the can ringing / resonance noise of my 6384S Motor
Pole pairs is 7 unless you’re running hubs or something weird. Gearing is the ratio between the large pulley/gear and the small one. For example 32 teeth on the large and 16 on the small would be a ratio of 32/16=2/1 or 2-1.
It shouldn’t. The switching frequency is so SO much higher than the audible resonance frequency (an order of magnitude at least) that it should have basically zero effect.
The main noticeable difference other than the sound, will be efficiency loss/heat generation in the motor’s iron core at very high switching frequencies, where skin effect and eddy currents start to become more significant.
Honestly I never even messed with mine while I had it. I just went straight to FOC for the buttery smooth quietness and never looked back.
I see
I just fear the FOC Mode because I have a maytech VESC and they are not known for their good FOC Compatability.
What do you guys discharge your Pouch LIPOs to? I’m think in between the safe 3.7 and lowest 3v, going to say 3.5/3.4?
I run mine with soft cutoff 35V, hard cutoff 33.5V
Whole thread for this subject
Thanks
anyone got the weight of a 6x2 tire
dont mind which one just need a rough weight
What do I do? Middle of my ride and packs given up… Don’t wanna take it come because it can combust at ant moment…
Dump it in a bucket of sand?
Probably, before it starts a fire in the open. I’d come back later and try to salvage the cables/connectors because i’m cheap
Getting a bucket now
Same – cut off the wires, put it in a bucket of sand, and drive to your nearest dangerous trash handoff location Would be irresponsible to drop this at your local grocery store’s dead battery box
50 PSI, Bluepenguin gave me some good advice for the situation, I’m gonna mess with the “throttle ramp down” setting
Yeah that’ll simulate less rolling resistance
I would still recommend playing with the PSI a little more first. I think you’ll probably like it a little more with a slightly higher PSI. Plus better range
yes. You can continue to the site or skip until it’s fixed
