General discussion

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:

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
