pF: adding sensors
I skipped talking about the sensor part. Here it is: (Lots of thanks to Shane for explaining this to me and creating the diagrams below.) Hall effect sensors are glued in between the stator teeth and they detect the pole orientation of the rotor magnets as the rotor spins. The magnets alternate N-S-N-S etc, so […]

pF: hub motor complete, mostly
Lots of stuff happened between that and the last post, here’s what: Last time we finished machining the rotor mostly, so now onto the stator. I confess that it crossed my mind to put the stator adapter in a mill, indicate its center, and CNC the screw hole pattern. But who am I kidding, clamping […]
