metallic parts. Based on the assumption that only moving, metallic parts of a turbine cause echoes indelible by standard filtering used in radar signal preprocessing, a method of preliminary evaluation of such maximum potential clutters was developed. The method takes into account how great a part of a turbine is really illuminated by a radar beam and for this part calculates a RCS (Radar Cross Section) and its equivalent radar reflectivity. A very detailed description of the model is given in this article in order for it to be easy to implement in any calculation system. Discussion of the influence of the main simplifications assumed in this model, as well as a comparison of the theoretical results with example data in operational mode of radar work, are included in this article.

The work presents the design calculation and measurements of the Rolling Rotor Switched Reluctance Motor (RRSRM) for large torque/low speed applications. The design calculations for different motor constructions are made. The best model of RRSRM is finally determined. The static torque, no-load, load and thermal characteristics of the prototype motor were measured. The analysis of calculation and measurement results is presented. In addition, numerous suggestions for industrial applications are put forward.

Static torque characteristics and influence of the geometrical parameters of four phase 8/6 SRM on torque ripples coefficent were presented on this paper. The Switched Reluctance Motor is being considered for a numerous applications, which require variable speed, high efficenty, fault tolerance and low torque ripples. Design of efective machine require using of FEM model to estimation of the set of geometrical and material parameters. Electromagnetic torque of four phase SRM was obtained in result of solving FEM magnetostatic model. Dependence of torque ripples of the internal stator diameter, breath of the stator pole and the breath of rotor pole were presented and no extremum in that characteristisc was found.

Switched Reluctance Motor (SRM) is an electric machine, which produce torque as a result of variability of magnetical resistance (reluctance) for magnetic flux excited by current flowing in stator windings. SRM could be economically well-founded alternative for commutator DC machines in domestic and industrial applications from regard on many profitable constructional properties: simply construction, high efficiency, easy technology, low cost of driver, easy regulation of rotational speed, large reliability. Idea of SRM is not new. It was already well known former to first constructors of electric machines, but only development of power management technology, and CAD methods, allows to take advantage of SRM proprieties. At first, SRM had many of disadvantages, which were gradually eliminated. Improvement process is not finished at all. Currently this young branch of electromechanical engineering is quickly developed. Construction, operational principles, controller, switching arrangement, geometrical structures, FEM model and torque characteristics were presented in this paper.
