DerpBike

DerpBike was the electrification of a dirtbike with hybrid vehicle parts.  The project was disguised as an undergraduate thesis which allowed me to devote about two complete months of my existence to it.

1: housing a hybrid car motor

2: sensing rotor position in that motor, making it spin

3: making a spline coupling and a sensor housing for the motor

interlude: visualization of rotating current vectors

interlude: chainsaw driven generator concept

4: FOC implementation

5: Acquiring a dirtbike frame and attaching a powertrain to it

6: building a 400V battery, testing, moving on
