I’m working on a project for a slow-moving “push” vehicle and have issues gettiing the motor to spin. I’ve using a FSESC 4.12 ESC, BDUAV 6384 120kv motor and a 12v 20Ah SLA battery.
For starters, the BDUAV motor has only 5 for a sensor wire. From some research, I found that it does not have a temp sensor, so I’ve changed the motor sensor wires to reflect the following: +5v(red) TMP (blank/no wire attached) H1(orange) H2(white) H3(yellow) and -(black).
From there, I ran the VESC Tool and attempted to set up the esc. I’m using a hobby grade Futaba T14 radio and FMR-02 receiver. I can connect to the esc successfully, choose the PPM input option (with the icon of a RC radio) and see the PPM mapping when I move the proper stick on the radio associated with that channel. For this application, I wish to use the esc as FWD-REV, as such I tried to use the PID speed control option. When I’m finished with setup, the motor will not spin, only a bit of a whine and what seems like an attempt to move in either direction.
I’ll add that I tried to do the SETUP Motors FOC, where I also set up the battery type and 3S with 20.0Ah but cannot complete as it gives an error that there is a connection missing when attempting to spin the motors.
Tried “current mode”, got slight movement and then stop. Not quite one motor rotation and then motor will not move afterwards. Cycled power on FSEC and same thing happens again.

Have you been able to do a successful motor detection in the welcome and wizards tab? I see BLDC tab so it doesn’t look like you have done a FOC motor detection, and that would explain why it won’t spin
To be honest, I’ve never seen anyone use large motors with a 3s nor a 12v battery. You said something about FOC not working; have you tried sensorless set up on FOC? I don’t know what you meant by “missing connection”.
Silly me… I think I neglected to connect to the FSEC before doing the FOC motor detection. It has just been completed. Will try to proceed from here and report the results
