FSESC running rough recently

Hi forum,

I have a FSESC and just recently all of a sudden my Ebike motor (Mac/Puma) runs rough at speeds less than 18kmph.

I don't know why this happened. I didn't change anything.

The FSESC is about 4yrs old and ran perfect before. I did motor detection again but it stays the same.

It's a flipsky unit. Could it be that the capacitors are bad? I need 63v low ESR types right?

Should I just replace those?

best,

oger

Check all wire connections. If things like that happen it can be a bad solder joint on the phase wires or a connector that became loose.

Checked all that.

I even replaced the input power caps.

Also did the Motor recognition again.

Might update the firmware just to see if that helps. But I first wanna get a replacement. You never know with updates :-)
