My wife bought an electric 3-wheeled bike. It is kind of a Pedicab with an electric motor driving the front wheel - and you can also pedal. The bike would be quite a bit heavier than a typical two wheeled bike.
The controller for the motor is a generic 800W -48V controller. A couple of times now after using the bike for a bit the motor would cut out. I would examine the wiring, which is a bit of a rat's nest and notice that the wires are very hot and it appears that some of the wire insulation has melted at times, shorting out the wires. This appears to be the green and blue motor phase wire that are the hottest.
Any idea why this would be happening? Would the controller be trying to push too much current for the size of the wires? Any suggestions on what to do to fix this. Is the controller undersized for the weight/size of the bike.
Here are some pictures:
