The paper presents a technique to optimize electrostatic micromotors. The finite element technique is combined with different types of optimization strategies, one of them, a version of the evolution strategy is discussed. It further involves an auto

This paper presents a computer-based method for finding the optimum geometry of very small electrostatic motors based on the variable capacitance principle. Not only is the geometry taken into account, but different excitation schemes are studied, in

Miniaturisation and integration are the key words for future technical developments. They enable savings in space, material and energy. The accurate prediction of the physical behaviour of such micro devices is required to enable short development ti

The paper deals with automation of an extrusion-based 3D mesh generator to adopt it for optimisation of electrostatic micromotors. It shows that it is possible to generate relatively complex motor models very fast and reliable. Limitations of this te

The application range of micromotors leads from systems for the maintenance of fine tubes in power plants to inspection of blood vessels in the human body. One of the requirements for implementing motors in such applications, is that their outer dime
