Cogging and unstable battery voltage measurement

Submitted by Mastersam on Thu, 2022-08-25 11:03

Hello,
 
I bought a Flipsky FSESC 6.6 60A more than a year ago, but I began to use it on an eBike this week (with a 1500W wheelhub motor).
 
The motor has a lot of cogging even with the auto calibration, and first of all I noticed that the battery voltage measurement is not stable at all, even when stopped the voltage can oscillate very quickly between 47 and 51V (12s 20Ah 12C Li-po battery).
 

Flipsky 75100 with Flipsky VX1 remote -- do I have the wiring right? (VESC4 connector)

Hi all. Did a search and didn't find anything about this specific issue.

First time setting up an ESC so sadly I don't have a lot of experience under my belt.

For an electric snowboard project, I'm using a Flipsky 75100 with a VX1 remote. It didn't explicitly state anywhere what type of connector it needed, so I guessed VESC4 and it seems like it's the right type? Connects to the COMM wire.

Custom 75_150 board noise and not synchronized

Hi, i'm making VESC 75_300 based 75_150 board with smaller form factor.

 

It was very hard to just run motor few weeks ago, but after some parameter tuning it can run motor in sensored FOC mode.

I'm testing with T-motor U5 400kv, 6S lipo, AS5047P in Sensored FOC Mode on FW5.03.

BUT I am stuck at some point.

The problem is that when I increase duty over 5% at a time, motor screams and stop running.

FSESC75100 Doesn't Work When Unplugged

Hello,

I've got a 75100 and it works perfect.. until I disconnect it from my computer. When I do, the green light indicating it's receiving a signal from the controller dims, indicating it is not. I have the VESC connected to a microcontroller and can move my motor completely indepedent of anything I do on the computer.

It works fine even when VESC project isn't even open on my computer. But as soon as I unplug it stops working. Any ideas? Thanks.

Flipsky 75100 rebooting under load

Hello guys, first post here!

I’m trying to use a Flipsky 75100 and at the beginning everything seemed to be working fine, I was able to detect the motor parameters, the hall sensors, and to spin the motor through the keyboard.

However, when I tried to apply some load, the VESC entered in a reboot mode! I read that it was regarding the 5v 1A BEC!

Third party Android/iOS app

This mobile app was developed originally for a non-Vesc controller but later on was adapted for our 25kw version controller now running vesc firmware as described here: https://vesc-project.com/node/1477

The app has a bunch of original features such as weather forecast, moving map, online telemetry logging, and a few other things mostly geared towards ebikes and other light vehicles.
