Question regarding VESC over current faults and broken motors:
My brother ate street just now because of his âmotor locking upâ. Donât know if it actually locked up, or if the vesc just shut down, because if I type in faults in the vesc console I get multiple ones like:
Click to see fault codes
Fault : FAULT_CODE_ABS_OVER_CURRENT
Current : 118.5
Current filtered : 112.6
Voltage : 35.30
Duty : 0.296
RPM : 5552.0
Tacho : 52
Cycles running : 875
TIM duty : 2489
TIM val samp : 2
TIM current samp : 4200
TIM top : 8400
Comm step : 0
Temperature : 20.67
Fault : FAULT_CODE_ABS_OVER_CURRENT
Current : 141.4
Current filtered : 119.0
Voltage : 36.22
Duty : 0.166
RPM : 5377.1
Tacho : 18688
Cycles running : 948
TIM duty : 1395
TIM val samp : 2
TIM current samp : 4200
TIM top : 8400
Comm step : 0
Temperature : 21.98
Fault : FAULT_CODE_ABS_OVER_CURRENT
Current : 145.5
Current filtered : 117.6
Voltage : 36.14
Duty : 0.173
RPM : 5375.8
Tacho : 22264
Cycles running : 1018
TIM duty : 1452
TIM val samp : 2
TIM current samp : 4200
TIM top : 8400
Comm step : 0
Temperature : 22.35
And I can seem to trigger them consistently by going full throttle from standstill, which makes the motor make a clunk noise as if it had a loose magnet or something inside, and then the vesc will restart quickly (the motor stops spinning slowly, unless I pull the trigger again, so I assume the fault gets triggered, and vesc shuts down, and back up in half a second to recover).
I would open the motor up, but the pulley on it is stuck, and I have another mount and pulley anyway, so donât feel like bothering if you guys have had this experience in the past and could confirm that a loose magnet could trigger an over current fault.
Board settings/specs if needed:
10s4p
single TB vesc
Maytech 6374 170kv motor
Motor limits: +60A -80A
Battery: +50A -24A
Over current protection: 130A (default value)
Running sensored FOC
It was not a lock up. It was an esc cut off since you hit over current value of 130 or above.
You can change this value to 150 max I believe.
Now as to why you hit this value with just 60 motor amps thatâs another question. I guess it is just a spike from the sudden demand of amps and the esc isnât fast enough to limit that.

prepare for lots of reading my friendâŚno other way around it.

Abs over current faults are most often caused by a cold joint, or often a broken cap leg. I would search for that stuff before ripping the motor apart.

Alright guys what are the best Esk8 Slide wheels???
Been dicking around sliding on my normal board for awhile now and wanna try it with esk8.
Not the best slide lol
Mabye the venoms? Speed vents? 80mm kegels? Or the 76mm kegel core wheels I forgot the name too.
The regular orange levels are really good for sliding
Iâve heard the evolve stoneground wheels are really nice eboard slide wheels

Yeah, but evolve charges a shit ton
100$ for the stone ground

I was thinking these?

In turns of sliding on a push board you want harder rounded lipped wheels. Most esk8 wheels are squared edges. You could probably lathe them to a rounded edge and then the 83 kegels should go nicely

Yeah, ive done that with sand paper and a drill a few times lol.
Thats ideally what Im going to do.

Here we go againâŚ
Got me some 7" tires from @Ace for my build. I can clearly see on his pics that they are mounted on superstars. But when I put them on mine, i end up with a gap between the hub and the tire?? Is there something Iâm missing?
Damn. I am not even Noob question thread ready⌠°If your down, get up again, I WILL BE BACK GUYS°
â That was the last we heard from RazZerblade for months, but when he came back, we couldn´t believe his expertise and his gold plated esk8 with diamond shaped trucks and glitter griptape, and the integrated smoke machine-- (Comment from an esk8.news user in January 2020)

Unfortunately I physically have them. From China.
I hope theyâre comparable. The thing thatâs worrying me is 1.9Nm vs 7Nm of torque, which is substantial.
Slightly more disappointed in myself because I also need to bore out/purchase new pulleys because I didnât realize these motors have 10mm D-shafts, and I have 8mm round drive pulleys. And guess what, the superior variant of these motors come with 8mm roundâŚ
Hmm thatâs rough, ask FS if you can send them back or something? You can use them but they will cap out on amps so less torque for more heat

If only you knew that the cool thing wasnât grip tape but glass frit.

Iâd take the torque ratings with a big pinch of salt.
