Newer #dielectric fluids and #powerelectronics now allow #electrostaticmotors to be better at some applications than their electromagnetic peers.

> The main advantage of electrostatic motors is their reduced critical materials use. In particular, electrostatic motors don’t require copper windings or any rare earth magnets which are getting more expensive as demand grows for electrically-powered machines.
