General discussion

Morning all,

Interested to know if VESC - or an alternative open firmware - maybe capable of driving a sensored 540 sized 13.5t motor?

Class restrictions specify zero timing, 1s batteries, and selectable Forward/Brake or Forward/Brake/Reverse.

Ultimately I'd like to move from the typical high frame rate PWM control signals over to DroneCAN - or similarly capable open digital protocol and resolve a few minor issues around braking and reverse controls.

I have 3 motors / controllers operating the same way. When I set them to Current mode everything works as expected. Duty cycle will never fully stop spinning and I don't know enough to understand what it's doing. Here's a video of what I'm talking about:

Any ideas on how to make it work correctly would be awesome. Thanks!

Hi, has anyone used a resistor to help brake the motors through the VESC? 

My plan was to wire the resistors in parallel with the power supply and use an electronically controlled transfer switch to switch over to the resistors and use the regen braking function.

Here is a simplified diagram of what I am trying to do.

Greetings!

First of all, I need to clarify several things. We're building different 3 phase linear induction and linear permanent magnet motors in our lab. We used;

completely discrete h bridges (3 pieces for each phase)

bldc motor driver from amc (using fake hall input)

and all motors work flawlessly ! of course using sinusoidal or ramp changes motor characteristics but it is another topic.

For our last robotic application, we want to use vesc for linear induction motor.

everything works fine except when ERPM is between 48000 and approx 60000 then the motor is out of sync....(FOC,BLDC,sensored,sensorless...same probleme) !
PLZ Help!!! :)

Hi all 

Does anyone know if its possible for vesc to read more that one input from the controller ?

for example I’m trying to set up an tank style control i need

right stick - forward - brake - reverse  

left stick - forward - brake - reverse

my board seems to only have one channel input 

(Dual FSESC4.20 Plus(Pro Switch))  ?

Hi,

I am user an older original 4.12 hardware on a ebike with BionX rear motor and 48V battery.

It works pretty well, but after 15 to 20 minutes the motor seems bugging a little bit, current is not stable anymore.

Any idea to investigate this issue ?

Thanks

Anthony

Hello everyone. I have a question about operating a BLDC motor in FOC mode with the Flipsky 4.20. What type of hall sensors is this controller compatible with -- analog, digital, or both? I've wired up everything correctly but am still getting "bad hall detection results." I'm pretty sure the last time we oscilloscoped the hall sensors we got an analog (sinusoidal) signal. Any help would be GREATLY appreciated!

please delete！

thank you！

Hi guys.

Im having a problem with my VESC 4.12 

The Firmware is up to date And im getting the folowing fault code 

Fault : FAULT_CODE_HIGH_OFFSET_CURRENT_SENSOR_1
