Greetings, I am having some issues with VESCs and need some advice. Originally I had a 2 motor board that was geared a little too high (16 tooth motor-36 tooth wheel) but it was fast and fun. One of the DRV chips burnt out and I had that replaced. While I was waiting for it to be replaced I took the second motor off and road as a 1 wheel drive board. This quickly burnt out the second VESC. The VESC control software isn’t showing any faults so I don’t know if its repairable. Is there a way to improve reliability? Any help is appreciated. Setup: 16 tooth motor, 36 tooth wheel 2 6355 230KV Torque Boards motors 2 VESCS from diyelectricskateboards 1 6s battery and 1 12s. I would switch back and forth.
Only first you burning your drv has nothing to do with your gearing ratio and more to do that u ran 230kv at 12s and passed the erpm of the vesc and blew the dvr
The gearing is fine, its the KV rating of your motors, for 6s its okay but 12s no.
It’s hard to say what problems you’re having without knowing your VESC settings. The VESC is only as unreliable as you make it.
What symptoms is the second VESC having that is not showing any faults? Does it power up?
I wouldn’t use 12s on motors with more than 200kv since they could break the erpm limit. Could be the reason why.
Where you runing in FOC? Of you blew on VESC why you kept using the board? Why you didn’t stop, uses the 6S battery and try to replace your motors for a lower kv one or you battery from 12S to 8S?
Eboosted. When the ESC blew, I did only use the 6S battery. This is a commuter board and my bike got stolen so I was trying to use it until I could find a decent deal on a bike.
ThermalM16. The software connects to it and thinks everything is fine. When I try the throttle, the red light blinks three times and the motor does not turn.
For settings, I was running the VESC stock settings that it came with but I adjusted the voltage cutoff to be higher. I was thinking about running FOC but I heard it was hard on the VESCs. I was also running dual using a servo splitter and not CANBUS because I couldn’t get that to work.
It sounds like in the future I should only run 6s and that will solve most of my issues. I was wondering if someone could help me with the ESC settings. I seem to set it to exactly what others have and it doesn’t work. I am probably making a mistake somewhere. Any help is appreciated.
Is it possible he got the bugged firmware with the ramp up speed too high?
