Hello,

I use the VESC 75/300 for my future electrical go kart. I have SMPM 20 kW. I would like to measure and calculate psi angle (angle between emf and current). To do that I measure the angle between hall sensor and emf/current. My issue is when I measure the angle between my current and my sensor, my current is very polluted by a 5th harmonic. Is it normal to have one ? Is there anaything I can do to avoid it ?

Thank's in advance for your time.

Hi all,

I would love if someone could briefly explain the "Stator Saturation Compensation Mode"  setting in VESC tool V.6.00

Specifically if I choose "Lambda" as the compensation mode which is described in the help box as "This requires that one of the observers with Lambda Compensation is used"..

Does this mean the setting is dependent on another setting I have to tweak such as the 'Saturation Compensation Factor' or something else, or is the Lambda mode kind of automatic?

Thankyou,

Pete.

I am working on an engine driven, hybrid generator for a drone. The primary power source is my BLDC in regen braking mode. I have an 8HP engine driving a Flipsky 80100 7KW BLDC. I have a 12S2P LiON battery in parallel with the BLDC regen output and the load. The battery is intended to soak up voltage surges, act as an emergency power source in case the engine dies, and in general be a very large capacitor. I am intending on starting with the battery nearly at nearly 100% SOC, and have made a circuit to limit the max output voltage from the BLDC to about 48 volts.

Is it possible to programme a VESC to flatten out the discharge curve of a battery? For example when the battery is fresh there is plenty of power so you dont need full throttle, Perhaps the VESC could compensate for this, whereas as the battery voltage depletes more throttle is needed. 
Is there a way of adjusting the throttle calibration/ introducing a limit and then adjusting that as the percentage of charge drops?

Does anyone have any experience of doing this? 

Thanks

Hey all-

I purchased two of these in early 2021, and one has been sitting on my shelf since then. Was used once for testing, in the aluminum housing, never been opened or modified.

looking to get $400, or best offer (unsure how much these sell for).

send me a pm + thread reply because I probably won't see a thread reply :)

I need some help with reverse button. I have an "Ewheel ADC adapter V2 for diy ebike escooter with vesc". Everything seems to be working well, except the reverse button. I read many threads here, from what I understand, if you select ADC as the APP, the firmware will use the RX to GND to reverse. Tried that and it did not work.

Also tried to use ADC+UART as the APP, in this case, I saw that the servo pin connected to GND will reverse the motor direction. Also did not work.

Hey there,

Hoping someone can help me out with a postulation.

What happens if the voltage of the battery drops below the HFI start voltage? Does the HFI adapt and only apply the voltage it can or does it throw a fault?

Thanks

Hi guys

This will be my first post. Hopefully not my last one.

First I would like to write some facts about me.

42 yrs old, 2 kids, located in Zürich region directly at the lake. Mechanical engineering background. Lotus freak and DIY man.

I am developing Jetsurf Boards for over 10 years now.

Actually all the boards are equiped with Lehner TorQstar 7040/50 and MGMs 20563-63. And a self developed remote (togehter with a Software engineer).

4 Boards are running and all is good.

Hello, I have a Flipsky 4.20 plus with a VX1 Pro remote setup running as a replacement ESC for a MEEPO NLS.  I am able to set everything and run the setup in VESC but my remote always ends up disconnecting for some reason?  The remote looks like it is still connected but the wheels just stop responding.  I have tried to change several parameters with no luck.  I have noticed in Tools, console that there is a Binding loop detected for property error.  Does anyone have any recomendations for this situation?  Thanks

Hi All,

I recently got back into using VESC's after a number of years out of the game. I have a very particular application this time around.

I would like to use the current control scheme for most of my operations, however, I would like to switch it into position control when the throttle is brought to zero. To hold the motor in a particular orientation.

I am aware this can probably be done by creating my own app. Is there any existing way of achieving this functionality?

Any insight is welcome!

Thanks!
