So I’ve got a problem: I’ve recently noticed a bad clicking startup on my motors… It only happens when accelerating and isn’t there when i get rolling a bit faster. Since then i swapped the hanger and put some new belts in (since one motormount was loose, but that’s another story). Conclusion: It’s not beltslip.
The startup feels like unsensored motors but they are sensored and the vesc tool detects the sensors.
Motor detection works fine.
Setup:
Trampa 6364 136kv sensored motors
2x flipshite 4.12 vescs (originally running in split ppm but now I’ve added a can-bus cable for the metr pro to work)
12s6p 30q battery
APS mini remote
Trampa 2017 pro belt drive
belt is tightend and wheel pulley alinged when wheel is put on, don’t worry
Moving stator is not good, seems like you will need to take the motor(s) off, check how is the stator fixed on the mounting plate… Might need motor disassembly.
EDIT: Also, how is the motor mounted to the mount? Are the standoffs secure enough?
Moving hall sensor board with some tweezers…
Weird thing tho: the stator is not rubbing against the magnets and the can isn’t loose like in @malJohann s motor.
Also both motors have this problem and I think it’s pretty unlikely that the screws broke at both motors
So I just rethightend the screws and the hall sensor PCB doesn’t move anymore
Now I’m gonna do a motor test to verify and then put a shit ton of locktite on these screws
I have had that happened to me and it turned out to be a loose phase wire connection between vesc and motor “bullet”. Check all of them and make sure they’re properly seated
Edit: they can become loose even when they have heat shrink wrap insulation
Haha. Yup. Mine were also tigh “or that’s what I thought” but While riding I managed to put enough strength on the phase wires that one of them became undone to the point that it was still making contact but motor would have the same behavior as yours during take offs
I wasn’t so wrong
