Hello,

i have an 10s battery and the limit output on vesc 4 hw 412 is 25v

Hi all -

I joined and tried searching through the old posts, but could find anything particular to what I want to do.  I would like to use vESC to control a BLDC motor for low speed operation for a piece of machinery with a pot/rheostat and possibly later with an Arduino via PWN/PPM for more granular control.

The current motor is a AC/DC Universal motor, 1.2Amps, 1/15hp. Its like 150Watts computed electric power. Think sewing machine motor.  

Howdo,

I've two VESC 4.12 boards and will be connecting them via CAN and controlling them using a VESC Wand.  One thing I realised only after buying the latter is that it doesn't have a deadmans switch and that it'll be using the UART.  My previous plan was to make my own remote and that there'd be an Arduino connected to allow for other things like light control (brake lights for example) as well as data logging.

I'm looking to use 18650 batteries to power my mountain board and can't figure out if I'll overload the VESC controller if the voltage varies. The voltage required is 22.2v - if I use batteries which can produce between 25v and 45 v does the controller handle the greater than needed voltage input ?

thanks for any help!

I had a strange fault on a makerx A200 after the hubmotor sheared the key and rotated the axle ½ a turn, shorting out the phase wires.

After fixing the motor it ran really poorly and having trouble starting the right way (sensorless) and often cogging like crazy. I checked phase outputs, gates, current sensors etc. with an oscilloscope and to my limited knowledge everything looked good or at least the same between phases.

Why my VESC TOOL did not have "balance"?

where can I find it?

thank you.

I am trying to repair a friend's dual motor Trampa mountain board.... He managed to trash the CAN and comm cables and ripped the power connector off the battery meter.

I don't know what if any damage he did to the actual electronics, although I don't see any obvious issues like burned / blown components...

So it's my understanding that, ideally, regen braking intensity should reduce or be entirely eliminated under several conditions, such as: batteries too cold temperature, batteries already full.

In these scenarios, it would make sense to actively brake by applying negative throttle and using battery power to reverse the motor against the natural flow.

Hi 

I am new to use VESC and I know that the ppm input is used in VESC. As my RC receiver is CPPM which is not support by VESC, I hope to use PWM as input for VESC. Can I write a cutomer app for PWM input? and how to configure PWM pin and c code for it?  

Thanks in advance.

My VESC 6 produces 0.8 Hz current oscillation on level ground with FOC at max speed.  I've tweaked the Observer Gain from the default 17.8 to 9 and 35.  I think 35 was worse, but 9 didn't fix it and I feel like I'm tapping in the dark.  Maybe someone has seen this behavior and knows the cure?  Also, oscillation feels stronger when the battery is full (41 V) vs. 37 V.
