Hello o/
I got to the point of just guessing and changing values randomly (which is bad of course), so at this point it's better to share tha pain and see if someone have any new ideas.
Dear Forum members
Hi All,
Maybe this is a bit off topic,
After doing a lot of testing trying to figure out what exactly was causing roughness during transition from sensored to sensorless mode, I noticed that currents were not smooth in sensored mode and especially bad during sensorless transition.
There is a clear indication of deadtime distortion happening during transition to sensorless and, in fact, most of the time while running in sensored mode. Motor phase graph was showing bumps and troughs as well. As shown on the pictures below. Once past the transition, the currents and phase line become smooth.
Hi everyone,
This is a real newbie question but I was woundering is the VESC 6 MK/V would be appropriate for a motor such as NEU 1509/1.5y /F/fan 6.7 (https://www.espritmodel.com/neu-1509g-series-motors.aspx)
Thanks
So, to supplement my DIY Onewheel, I want to build a "siren" that increases in volume and pitch with increasing motor duty, being fairly quiet at 50% duty and absolutely banshee at 80% duty. I'd prefer to implement it outside the VESC because I don't really want to mess with the VESC software, I'd rather leave it 100% dedicated to motor control.
Two questions:
Hi all - I've spent weeks searching this topic - everyone explains what regen *is*, but nobody seems to explain or know *how it works*.
How would my VESC take the voltage from my motor, and then use this to charge up my 58.8volt pack? - especially given that when I am using my brakes, I'm going slower and slower - *way* slower than my motor KV, so my motor is never going to be making anywhere near enough voltage to charge that 58.8 pack with ?
Please help i can not put the proper firmware on my vesc need file for version 4.0
Hi everyone. I purchased a Raptor 1 four years ago and got so fed up trying to program the Vesc that I put it in the garage for 4 years. I recently began reading articles to try and revive my 2 boards. I recently revived my Trampa mountain board after 4 years in the garage and that is working fine! I got the new VESC tool and found a bad drv chip on one of the the Raptor VESC, purchased a new VESC and updated the firmware on both. During motor set up I get a quick COG followed by what sounds like a "spinning or ringing" sound but the wheels are not moving.
Some of the cheap brushless ESCs have an option to control "Top Speed" with one Pot with another Pot controlling acceleration. Given there is no good way to know motor RPM on a sensorless motor I'm wondering how this is achieved? Given these cheap brushed 550 motors double their speed going from 12 to 24v, I'm wondering if there is a way to cap voltage (top speed) while not impacting the acceleration.
I'm using Duty Cycle in the ADC Settings and DC settings are all default.
Thanks - Kirk
