I believe we are going to have lot of these in the near future since our president vision of year 2020 is to make Maldives carbon neutral. I guess this would make good business for me, eh! So now I am starting and I too have a vision. To fix the Motor drivers. hehheheheh... Below is the spec of a typical motor controller of a Battery operated two wheeler we have here. From the label it is clear that china is already carbon neutral ..I mean they are the guys responsible for making the PWM. My goal is to fix the driver at a cheap price. I got my hands on one of the faulty one, which by the way came to my, as usual, after the infamous wannabe's says it cannot be done. My diagnostic relieved that the MOSFET's need to be replaced. The drive config I believe is 3 phase induction motor control type. Cycle uses two 12V batteries ( the info I got, as I haven;t yet seen the battery compartment of a typical cycle yet ). According to the controller the motor is around 800W. By looking at the wiring of the conroller leads me to believe it is a 3 phase induction type. Customized for cycles.
