DESIGN OPTIMIZATION OF AN ELECTROSTATIC MICROMOTOR WITH AXIAL FIELDHistorically, the idea of using electrostatic phenomena to produce motion has long stimulated the activity of scientists. Although the power generated by electrostatic motors is modest, the absence of windings and ferromagnetic material makes this kind of device competitive for applications characterized by low levels of torque and reduced volumes. During last years a renewed attention app... ...

INTERACTION OF ELF ELECTROMAGNETIC FIELDS WITH VARIOUS MODELS OF THE HUMAN BODYThe interaction of ELF‐LF electric fields with the human body is examined with a method based on surface charge‐integral equations. The evaluation of the electric field intensity on the body surface is performed for a realistic model of the human body. Two examples for different postures of the model are given.

The use of affine arithmetic for thermal state estimation of substation distribution transformersThermal protection of mineral‐oil‐filled substation distribution transformers is of critical importance in power systems. The failure of such a transformer is a matter of significant concern for electrical utilities, not only for the consequent severe economic losses, but also because the utility response to a customer during outage condition is one of the major factors in determining the ... ...

Comparison between finite element method and magnetic equivalent scheme to model an induction machineProposes to compare two models ‐ finite element method and “magnetic” equivalent scheme ‐ for numerical modelling of electromagnetic systems. Both these approaches coupled with electric circuit equations take into account saturation effects. Uses a machine of 5.5kW as a model to show the validity of these approaches. Compares the results obtained from numerical calculation with experimenta...

Fast analytical model of induction motor for approaching rotor eccentricityDeals with the problem of the electromagnetic torque calculation in the case of either nonuniformity of the air‐gap or eccentricity of the rotor. The electromagnetic field distributions have been evaluated for drag‐cup motors. An analytical model has been introduced for linear motor based on the variation method for magnetic flux density magnitudes. The total torque and its components have... ...
