VESC problem. motor won't spin


#1

I assembled my esk8 last week and I rode for an hour withouth problem. Yesterday my friend was testing and it stopped. When he come back a phase motor wire was loose. I connected again but not response from the motor.
I have check all the conection, I’ve tried another motor and still no response. Also I’ve changed the battery for a power supply in order to check all the component so I tend to think that the problem is in the Vesc but not sure.
My Vesc is a 4.12 turnigy.
There are apparently no burnt or damage component. I can connect to PC and receive response. Light green/blue ON. No faults on terminal. Firmware updated again.
Everything seem OK but when I try to config the motor no spin nor other sound.
Any advice in how to confirm that is my VESC that is broken?

Setup:
sk3 6374 168kv
2x6s 4,5 lipo turnigy 40c
vesc 4.12 turnigy
BMS (Chinese bypassing) -> Removed to test

With everything plugged up and on, check to see if your fet on the vesc is getting hot. If so, its popped inside.


#3

No, it’s cold.


#4

Do you have a voltmeter? If so, check voltage throughout the system. You may have a loose connection on the vesc or leads in motor came off… Not being able to see it does leave us in the dark though.

go on vesc terminal and type fault to check for errors


#6

Yes, I tested in all points and everything seem correct except inside the VESC because it has the transparent insulate. I will broke to test it but the VESC indicates a correct voltage.
I’ve added some screenshots in the first post.

No faults

thats good…no DRV fault. did you try to do motor detection again?..just for the sake of it

edit: just saw that you tried that

@DaniRC
Try to reset the values to default and then give it a try.
Also check by re-flashing the fimeware on FOCBOX again


#9

I did and it didn’t work but I will try again with crossed fingers :relieved:


#10

It think that is a DRV problem. I’ve broken the insulate because it had an sticker and I wan’t able to see the last corner. Although I don’t have any DRV fault, it seem that it is burned.

any place to repair in Europe?

@Martinsp :smile:


#13

@DaniRC These ESCs are not good. Have you tried FOCBOX?


#14

No yet but I’m going to buy a new Vesc. Don’t have focbox the drv issue? It cost more than double with shipping to Spain… Three times if I include the additional warranty :cold_face:
