Third Party Hardware

Hi all,

I ran my FSESC 4.20 based on VESC 4 through VESC tools, updated the firmware, changed configs as I saw fit and configured input all good. After disconnecting, the ESC seemed to be working fine, it controlled the motor just as intended and reacted quite well to the input commands. However, when I tried to reconnect it to test a different input method, the PC wouldn't recognize the FSESC 4.20 anymore.

Hey all,

as you know, i build a custom pcb for my DPV (something like https://www.carbon-scooter.de/scooter.html#mono). I use a outrunner 60kv motor with 40A maximum motor current.

In BLDC mode, it works fine out of the Box. I reach a maximum eRPM about 25k @95% duty cycle and 23A motor current in rpm controlled mode. The DPV is fixed with a cord, so i measured a static maximum power. But in BLDC mode the dpv sounds under water like a kitchen aid and i want to use FOC

Hello,

we are currently testing a slightly modified version of BESC G2. 

While testing, we faced a strange behavior. Under certain conditions, the PWM input signals of the gate drivers gets some kind of "unstable". In detail, the duty cycle is suddenly incorrect (too long) for individual pulses.

The circumstances under which this happens:

This is proof of concept design that im going to use later do make 16s (hopefully over 50a) Vesc for my e-bike.

I have a VESC from Maker-X Tech and it seems a certain part has gotten damaged.  I want to know what this component is and if it can be replaced.  Any guidance would be helpful.  Thanks.

Hi

ive been crawling through but are unable to find any leads !

i looking to purchase a plug and leads to fit the comms port so as to run an analogue throttle and brake.....any leads or links greatly appreciated !

Hi, I own a Tenka and I can't make the motor setup work.  I tried with focbox UI and vesc tool for android.  Anyone made the tenka work with which app? Thanks

Hi all,

i started adding LoRa support to the vesc fw. Maybe someone else is interested in this and is more familiar with the firmware code :) and can help me to improve it.

It could be interesting for a long distance remote, maybe for some glider winches

Hi all,

i tried to change the maximum input voltage parameter for my custom board. i defined the MCCONF_L_MAX_VOLTAGE in my hw_conf.c file of my custom firmware, but vesc tool still truncate the voltage to 50V. is there some other place to configure the limit ?

thanks

Hi all,

once again a question about current sensors :) I read a topic about current sensing here in the forum. Someone used the ACS71240 as current hall sensor.

I like this kind of current sensor and looked around  a little bit on the allegro web page. Two devices looks interesting to me

- ACS72981KLRATR-050B3

- ACS71240KEXBLT-050B3

but both are difficult to buy. are there any places you know where to buy ? Or some other chips with the same function and the same package ?

Thanks

Georg
