Shinsei corporation made a (macroscopic) electrostatic motor that operates on that principle. I guess they did it just out of curiosity because I don't think it has many advantages. It required high voltages and all the active surfaces had to be highly polished to prevent electric arcing. If I recall correctly it had to run in vacuum as well, for the same reason. But it was a pretty cool project.
- userbinator 5y agoElectrostatic motors have been around in some form ever since the earliest experiments with (static) electricity, so they predate even electromagnetic motors. The high voltages required and their relatively low torque has kept them from gaining much use. https://hackaday.com/2017/10/03/ben-franklins-weak-motor-and-other-forgotten-locomotion/ https://hackaday.com/2017/10/03/ben-franklins-weak-motor-and...
