I'm having trouble getting my underwater thruster to operate smoothly with the Flipsky Single 6.7 PRO ESC 60A Mini and the VESC Tool software.
The thruster has no bearing, a thin waterfilm is created as soon as the rotor starts to spin and this serves as bearing. It should be in sensorless mode as I don't have any hall sensors.
I've run the FOC setup wizard, and the motor makes really nice fast and slow rotations, but when I write the motor config and when I try to control it myself, it struggles to start at low RPMs, and the rotations are not smooth at all.
I'm wondering if anyone else has experienced a similar issue ? Is this issue coming from the type of motor itself or did I do something wrong with VESC tool ?
Any help or suggestions would be greatly appreciated. Thank you!
