Jigsaw Motor Uses PCB Coils For Radial Flux
https://hackaday.com/2019/07/16/jigsaw-motor-uses-pcb-coils-for-radial-flux/
Electric motors are easy to make; remember those experiments with wire-wrapped nails? But what’s easy to make is often hard to engineer, and making a motor that’s small, light, and powerful can be difficult.
