“Another BLDC motor controller?” you might think ... For starters, he’s closing the loop with a Melexis MLX90363 hall effect sensor to locate the rotor position. Simply glue a small ...

The Hall effect sensor output from motor can be observed along with PWM inputs on oscilloscope. This technical note provides the description of ongoing internal project to setup closed-loop speed ...

The design of the fin took a few iterations to get right, but with a working motor and fin combination he set about tuning the system’s PID controller ... strapping a sensor to the pedals ...
