Dear All,
I got kicked into a project where they previously used a 2x(JETI controller and a Motor brushless outrunner (Hemotec 105.20 KV135)). Due to my little experience with the VESC 6 I was able to convince them to go for the VESC 100/250 - because and also of the CAN capabilities.
So I am using a VESC for a project where I am re-doing an Kreweser electric trike-cooler-scooter-thing and have done most of the wiring but hit two spots that I could use some insight on:
Hi,
just bought the Maker GO-FOC Hi200 ESC from Maker X. It had 5.02 firmware on it but I could not get the input wizard to run on the latest Vesc Tool. It said something about unsopported firmware. The Motor Wizard worked just fine. So I upgraded(to 5.03) and now both wizards runs fine but something is wrong with the motor settings because the motor is very jerky which is was not on 5.02. So lets downgrade I thought. But I cannot get it to 5.02!!
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,
Joep
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?
