Electric brake issue

Recommended Posts

Hi everybody,

I have bought a Ninebot Segway es2 a couple months ago. Since yesterday, i have an issue with the frontwheel: it doesn't turn well. It's not locked completely, but it severely impede the turning. It doesn't allow to use it, because when i try to start, the system automatically switches off. It's like the electric brake is always on, even when the scooter is off. It looks like a software problem.

What can i do? Reset it?

My bet: Back EMF because of a blown MOSFET. 

In other words the wheel motor coils are shorted by a blown semiconductor.

Happened on my X3 after GF oversped the motor. It feels like the bearings are frozen.
