Okay so I just started using FOC mode on my Vesc and I noticed something odd. My motor RPM spins faster when I am at a lower throttle than when I am at a higher throttle according to the real time data graph. I am in current control mode.
I tested it using a different remote so it isn’t a remote issue.
I also tried using @Ackmaniac firmware, same issue.
Here are the images of the RPM graph below, the first one is when I am at full throttle and the second one is when I am at around 20% throttle.
I assume this is on the bench since your motor current is under 3A? May have something to do with your Battery amps being higher than your Motor amps, but I am not the expert on this. @Ackmaniac?
i’m using a focbox, actually i did never feel that when ridding…weird!!
in another setup i have this doesn’t happend in bldc, did you have this issue in bldc?
Both pics are at 95% duty. Throttle in current control doesnt work like most other esk8 brands. Throttle in current control controls acceleration NOT speed. So without a load even a tiny bit of throttle will ramp the motor up to full speed. The two pictures are essentially the same.
HOWEVER, there is a bit of weirdness with FOC on 2.xx software where sending more current at max duty will cause the motor to change in tone (and in this case lose ~1000erpm). I’m not exactly sure what causes it but the problem doesn’t exist in f/w 3.xx.
