Hello, I have been reading and learning a lot here over the past weeks as I ordered parts and got ready for this holiday project with my son. Great community, hope to give back soon. Right now unfortunately we are looking for help.
So we just finished bench testing and took it out for the first test ride around the block. Wow were we so excited to feel that power under our feet. Really scary but so much fun. We took turns and rode it slowly around the block, no hills.
After about 20min it suddenly stopped working with plenty of battery left. We can still connect to the VESC with the BLDC tool and read/write configurations. However the motor detection fails. There are no errors when running “faults” on the terminal. On the “Realtime Data” tab we cannot see the last line, so not sure if any errors are there. The VESC has a red light blinking, double flash followed by a pause. We checked the wires and can’t see any issues with the motor connection. Motor detection worked fine earlier today, we ran it several times to ensure we use the correct parameters.
Any thoughts on what might have gone wrong and how to further investigate are much appreciated. At this point we don’t know if it’s the VESC or the motor or both. One other test we did was to run motor detection without the motor connected and it looks exactly the same.
Here are our main components:
- VESC from
- Motor SK3 6364 190kv
- Battery 10S - 2x 5S 5000mAh Lipos
