Voltage Constant Measurement Using VESC Tool

Using a lab power supply and VESC Tool, you can observe the voltage constant of an electric motor.
How do i measure internal resistance of each group in a battery so i can tell the BMS so it take it into considération ? Probes on each side of the group ? Do i need to isolate anything ? Thanks
Thanks. Simple and helpful.
Now can you deminstrate why i keep having fucking issues with my bs fucking vesc i understand the entire software and hardware but my shit just randomly foesnt fhcking work fucl
Hi! I can't understand why use batteries with low number of series blocks and high number of parallel cells, if higher voltage gives us more speed potential even if we have a speed limit, and the battery current decreases due to voltage increased. Maybe its about peak currents in PWM of the controller?
What is the best mode for a bike with a mid drive, duty cycle or current motor?
I have a VESC controller. I have everything hooked up . But don’t have any regeneration. Any chance you can show me how to turn it on?
Великолепно товарищ! Я рад лаконичному и чёткому обучающему видео. Хорошего дня!
These videos are a god send. Thnak you so much for doing this!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Your videos are great. Thanks for the quality content.
Voice too low cant hear you
Voice is fine thru earbuds
hello, can you make a video about the saturating of the stator, in my case each brake the observer looses the position of the stator and so i have litle cutouts and no smoothly brake. I am using 20s liion battery with 60v1200w 10" hub motor. battery regen current 25amp and motor max cirrent 85amp, absolute current 150amp. Trying to adjust the observer or make stator compensation didnt helo
What do you think would be the best settings for the scooter's 52v23Ah 1000w motor, hopefully I would like to increase acceleration and speed.
Great,, Informative 👍🏻👍🏻. Keep posting
It does not work at all. Motor stops with Over_current when current goes to limited value. For example I set 90A (abs max current is 450A) and I have overcurrent. But chart shows that maximum current is about 90A. Scheise... Limitations work only if I set it about 3 times less than nominal power. It's very bad.
happen to find fix?
Cool stuff subscribed. Quick question how did you log current data?
Awesome thank you! I wish there was a Video like yours 3 Years ago.... would have saved me ton of money and time.
Hello, great content. Just a quick question, why is the "current in" on your graph so much lower than "current motor" on your graph? I noticed the VESC draw at the battery is a lot lower than my other controllers.
It would be interesting to see the results of field weakening graphed.
Thank you for this!!
This is why Debodge said that its best to have your controller as close to the motor as possible because motor in torque mode means high current and u dont want to have long phase wires.
I think I will have to either learn Python or C in order to better understand VESC!
Thanks for the video 👍🏻. would you be able to speak either closer to the microphone or a bit louder I can’t really hear you that well.
Thanks for the feedback. I'm working on upgrading my audio setup.
Can you explain Cycle duty?
Definitely. I'm working on that for a future video.
@@understandinglightelectric3946 great, thanks
Sharing🤙🏼🤙🏼🤙🏼
Excellent thanks alot🤙🏼🤙🏼🤙🏼🤙🏼
Good info, I ride eskate and there is always a confusion when asking g people. They all have their own opinion but no proof. Thabks for sharing new sub Here bro.
Appreciated, I'll keep slinging these graphs.
@@understandinglightelectric3946 and I'll keep sharing them Bro, thanks, very helpful 🙏🏽
do this video again with brushless motor or 3 phase motor and how those currents relate or are calculated.
Great suggestion. I'm working on a good explanation for a later video.
