Novel differential linear electrostatic motor with light weight rotor

The paper proposes a new type of linear electrostatic motor operated on a principle of the electric field effect on dielectric material. The proposed motor has a simple structure that simplifies the production process. Moreover, the motor is designed with very light weight rotor. As a result, the friction and power losses of the motor are reduced. Additional advantage of this motor is that it is not influenced by external magnetic fields. Furthermore, the proposed motor has advanced motion control options that allow precise control of velocity and position profiles. Extensive simulation results of the proposed motor at different operation modes are presented and analyzed. The simulation results demonstrate proposed control methods and show the practicability of the motor.
