Help! the motor can't handle the board weight

I’ve attached the VESC settings, thank you


i clicked the motor detection, the wheel is spinning but in the BLDC tool appears the message detection failed, any idea?

About sensorless in the BLDC 5th screenshot i selected sensor less.

After… You need to do apply and write

You have A problem… Specialy I you try to run without detection

Do you have any Picture of the motor connection. And have you send a e-mail to enertionsupport

hi again,

i’ve tried some vesc settings to check if BLDC tool can detect the motor.

settings number 1

i get this settings from this thread

motor detection result: detection failed (the wheels are spinning with the tool and the controller)

video skate on the floor v1

Motor settings v1 - BLDC motor detection

Motor settings v1 with controller

settings number 2

i get this settings from @onloop youtube vídeo (i think his motor and vesc are the same as mine)

motor detection result: Detection results: Integrator limit: 108.62 BEMF Coupling: 699.49

Hall sensor detection failed: -1, -1, -1, -1, -1, -1, -1, 3

video skate on the floor v2

Motor settings v2 - BLDC motor detection

Motor settings v2 with controller

@JohnnyMeduse this is a short video of my setup

some questions

1- about the settings 2 what does it means the error “Hall sensor detection failed: -1, -1, -1, -1, -1, -1, -1, 3” ? what i can do to solve that?

2- i’ve tried to stand up on the board with settings 2 and i don’t feel safe, it’s normal that the skate starts running so fast? what i’ve to change from settings 2 to start slow as the settings 1?

3- can i burn/break the vesc or motor with the settings 2? which are the best vesc settings to prevent that and be safe?

thank you so much! i’m happy today to see some progress :smiley: a few days ago i felt like i put the money in the trash haha

Thanks and on problem et are here to help :blush:, and you did most of the work :raised_hand_with_fingers_splayed: Also, try the batt max at 45, batt min at -12 and max Erpm at 70000 (this should help Protect the vesc)

No problem there, you have sensorless motors, thus no hall sensors. Nothing to detect

sorry, one more question…

if i change the max erpm to 70000, i have to change the min erpm to -70000 ?


Only if you want to be a wild card and use it in reverse :stuck_out_tongue_winking_eye:
