After approx 700 miles my DIY project:
http://www.pedelecs.co.uk/forum/electric-bicycles/6859-my-diy-electric-brompton-project.html?
has developed a fault.
The symptoms are that the motor judders a little but then goes silent when pressing the throttle button.
Actually it did the same thing about 300 miles ago but came back to life without me doing anything and has been fine since.
I have got a spare motor and spare controller etc so could try swapping them but it's quite inconvenient given I'd need to sort out connectors etc.
The motor is a brushless/sensorless tongxin. Would I get the symptoms described above if, say, one of the 3 motor wires had come undone or broken somewhere?
I wondered if it was a broken controller but thinking about it, since the fault occured before but then recovered it feels more like a dodgy connection.
My suspicion is the mini sureseal connector I used to connect the motor is not making a reliable connection. Everything got very wet last night when I cycled home in the rain/sleet/snow so this may have something to do with it.
Failing that, is it possible/common that a wire could get broken within the motor itself?
