VESC FW 5.x - Beta Testers wanted [SERIOUS]

@Deodand What is the word on motor detection with belts and drivetrain attached? Do you think it matters? I’ve heard both ways over the years.

I just did an experiment and it’s not really changing the numbers much at all, having the belt and wheel connected. However, changing the firmware version changes the numbers a significant amount.


these are consistent with or without drive train connected

TB6380_3 new values detected at commits a8ccdba / 12a7106
I: 22.51A
R: 14.0mΩ
L: 6.01μH
λ: 4.335mWb

these were the average of several detections, all with no drivetrain connected

TB6380_3 old values detected with firmware 4.2
I: 23.37A
R: 12.20mΩ
L: 8.98μH
λ: 5.013mWb

Both of these were the same physical motor, ESC, and wiring. The enclosure hasn’t even been opened.

The drivetrain didn’t seem to affect the numbers at all on the experimental version but I hadn’t tried that test before.
