Hi jaykup,
I am drifted from eFoil channel into this forum (however, I have a DIY eMountainboard) and seeing some issue with my Flipsky VESCs. I was wondering if you can enlighten me. I have quite a big inrunner motor with 120kv and 10pole on a 14S 36Ah Li Ion Battery:
driven already by a 75200 (old version with white potting, watercooled) and now the new 75200 watercooled which is i guess same to the VERSION 75200 Aluminum PCB. I have stock FW installed (75_300_R2) and I have trouble to run my motor at higher duty. Here is a log from today:
The issue is, that the motor starts to desync / scratch / make noise and is not going higher speed at certain duty / rpm. I also have that behavior in BLDC mode (and FOC ofc). I have done several detection and tweaking on motor parameters but there is no effect at all. The motor does spin in air fine at fully duty. Also in start phase in water I can easy pull 200a to lift. Once flying with the Efoil the current drops (less drag) and rpm increase to certain point where it shows the issue.
Does this correlate with the low / phase shunt FW topic ? What would you recommend to me for trouble shooting? I was going to test your new FW this weekend. I spent already hours in and outside of the water to fix it, but I was not successful. Your support is very much appreciated,
best
Jan
