General discussion

Hi all!

I'm building a dual motor electric scooter. I have an Ubox V2 VESC, with an ADC adapter from spintend. Using the VESCTool it could detect the motors and the throttle, and I can see the voltage change in CH1 (0V - 2.5V) on ADC Mapping tab.  However the motors are not spinning regardless, completely ignoring the throttle position.

Throttle is working https://ibb.co/x5mZgj1

My very loose plan is to connect my handlebar inputs, such as throttle, break sensor, turn signal and buttons to my vesc, read the handlebar switches-ctrls from Lisp¹ and send CAN frames to my lights[^2] and horn.

How do I connect my handlebar switches to the vesc? In my example I'm have a Ennoid vesc and these wires from my handlebar:

Hi, I have a question, is it possible to upload a vesc to the motor driver which is based on stm32, it only has measuring resistors that measure the current from the battery, how does it look with uploading such a software, is there any pinout to define for it to work? Any of you guys tried something like this? Controller: Sabvoton ml60 in the programmable version, of course. Thank for answers!!

Is it possible to configure VESC to ignore the remote control signal, for example, depending on the state of a circuit coupled to a REED switch?

Is there a command I can issue to VESC based on the state of REED switch, so I can disable VESC response to the PWM control signal?

Hello, I have built this contraption of a vehicle we call the "tot rod" it has dual brushless motors a controlled by an 8 channel radio transmitter. I have an unnecessary amount of 20v power tool batteries at jus disposal, I've been running up to 4 of these depending on how far we are going.  20v get this around 12mph @ 20v with 4 batters at 20v it will drive around for hours. With 4 batteries at 80v it did wheelies and immediately burned up the ESC... this began my learning curve that brought me here. Ideally 40v is plenty. Can i rebuild these smoked esc units?

Is it possible for this software to control via an analog input instead of a pwm input? 0-5v reference signal. Not looking for complicated but this is the signal i can produce in my project. 0-2v %20 power, then a variable rate from there on increasing power to 100%. This will be a steady state application. Motor will stay on for long periods at low power then for short burst (max 10-20secs) be pushed towards full power.

Folks,

Which twist throttle and break lever works better with the VESC tool? 

Regards,

Hi everyone,

I am using a vesc 100/250 with an internally geared QS138v3 on 22S

Thus far I have the phase current at 320a and it is plenty of power. No issues.

I am wondering if I can get more RPM through the use of field weakening. There is no question that it will work but the question is if it will kill the vesc.

I am unsure about the inner working of field weakening however I was under the impression that it may increase the BEMF voltage at peak to above what the mosfets in the vesc are rated to and cause a melt down.

Good afternoon all,

I've a VESC 6 Mk5 that I am using in conjunction with a Teensy 4.1 in an escooter application.

To provide a robust and reliable emergency stop, I have a big ol' red e-stop button hooked up between the VESC and Battery via a solid state relay.

I had a bricked vesc that failed to program via swd then failed to even connect via swd. I did a fair amount of searching and came across a tip on the spintend website that deserves to be posted here for all to find more easily. First check if your vesc to vesc swd connection works the normal way. Watch the video: https://youtu.be/PFFiVxFHDM4 starting at 5:40. If that doesn't work, try this:
