I have been testing Vesc controllers for a couple of years now on my ebike and I have ran into issues when using dissimilar motors connected using CAN.
the problems all stem from VESC using ERPM as its basis for all the calculations, so when using 2 different motors or even 2 different sized wheels as it causes problems they don't match.
Hi,
I am having hard time understanding what does macro MCCONF_FOC_SL_OPENLOOP_HYST and m_min_rpm_hyst_timer variable do?
what is the meaning of hysteresis here?
what does the section of code given below do?
Hello,
I am looking to better understand the difference between ERPM and Duty cycle, when I log data on my board and overlay the Duty Cycle and ERPM, they seem to be doing the same things. What is the difference between these two parameters?
What is the difference between "Duty Cycle Current Limit Start" and "ERPM Limit Start"?
Hi,
I'm new in this forum I would like to replace my motor controller of my step (Joyor f5+) with a VESC.
Which one do you recommend and how do I choose the right VESC ?
Regards,

trying to find a suitable controller for an electric motorcycle I build.
Installed A Golden Motor 108 (quite similar to a MY 1020 motor).
it's an Inrunner (approximately 110KV), on a 48V.
Votol and Kelly did not synch with the motor well for some reason.
anyone have experience or estimation as to how well and smooth this combo will be?
I just watched Benjamin's tuning video https://cloud.vedder.se/index.php/s/jpm9Soiq68HBbdw and learned a lot.
But there's something I have been wondering all along: Why use sensorless mode when the motor has sensors?
In my case, it's a Golden Motor HPM5000 which I imagine was originally intended to be run with trapezoidal communication. As such, it has 3 Hall sensors.
We're trying to control the VESC Duty Cycle via CAN.
The controller responses perfectly as expected, until big input changes happen and the controller starts to oscillate and continue to output maximum Duty Cycle.
In this example we limit the Duty Cycle input data to send out a maximum of 81000, corresponding to 81%.
This image shows it follows the maximum 81%, until rapid changes happen and the controller outputs 95%, the absolute maximum?
I'm struggling to run a brushless motor via my VESC 4.12 controller in speed control, however, this was all working fine a few months ago. Now, when I command a speed via vesc tool GUI, the motor just grinds and I get the current/RPM sensor data linked below. When I tried to update the FOC parameters, during the process, the motor is spun up beautifully with no problem. Can someone explain how that might be, and/or help me figure out how to get speed control working again on my controller?

I don't see any type of setup process to do position control in any of the forum posts, Can someone please post and document the steps to do position control from vesc tool?. Many Thanks
VESC 6MKIV suddenly will no longer turn on. When the power switch is pressed it lights up blue as expected but only the red LED flashes once. The blue LED never turns on. Any ideas on how to trouble shoot?
