I just bought a brand new electric scooter and wanted to test how steep a slope it could climb. It seems the scooter didn't like the idea and after 200 m the throttle stopped working. I thought that perhaps it was some sort of current cut off protection mechanism to avoid overheating, but in fact it never worked again. Since the battery seems ok (the lights work, the battery level reads fine) I guess it must be either the motor or the controller what has stopped working. The motor was actually hot after the failed attempt to reach the top of the slope. May the heat have melted the Hall effect sensors inside the motor or something like that? Or is it more likely that it is the controller what has failed? I'd like to know what your guess is or if there is a way to find out, so that I decide whether to buy a new controller to try and replace the old one or not.
The scooter is a Huasha 50QT-17 with a 1500W motor and some JH-A48150-T3 controller. I have been unable to find the manufacturer website (JH from China?). I bought the scooter from an online dealer, and my guess is that it will be hard to get any information from him. The scooter has a brushless DC motor (Huari Group).
