An Extended Model for Ripple Analysis of 2–4 Phase Resonant Electrostatic Induction Motors

Electrostatic motors are promising forms of actuation for future robotic devices. The study of their different implementations should accelerate their adoption. Current models for resonant electrostatic induction motors were found not to be able to properly describe their behavior, namely, with rega...
