The paper deals with parameter optimization of a sliding contact equivalent diagram for a DC machine by the methods of artificial intelligence, especially by a genetic algorithm. The emphasis is put on reaching the maximum of sparking and the minimum of losses. Firstly, the equivalent diagram of DC machine sliding contact used is described, and its mathematical model is analysed. Secondly, a numerical calculation is performed. In conclusion, the sliding contact is optimized by means of genetic algorithms. The parameters are selected for the optimized solution, a purpose (criterion) function is created and the results of optimized values are obtained and discussed.

This paper is focused on the optimization of a DC machine constructional design using the optimized methods which are based on the artificial intelligence algorithms, mainly a genetic algorithm. The optimization should find a compromise between selected constructional parameters and the requirements for properties and operational functions of a machine to be designed. A machine design that was carried out by the "standard" method and a design of algorithm that performs the optimization using the genetic algorithm are described in the paper. In conclusion, the optimized calculation itself is performed and discussed. Results are presented and assessed, and the evaluation of a possible use of artificial intelligence algorithm for this specific optimizing task is carried out.

Single - phase commutator machines are usualy working in high speed and therefore the vibration analysis becomes to be very important. It has been observed, that the machine resonance range should be under the nominal speed and therefore the problems of starting procedure increase. The contribution deals with a problem of single - phase AC commutator motor mechanical resonance. The magnolie forces between slator and rotor were taken into consideration during analysis. The relation between forces of magnetic origin and of excitation current and nonuniform air - gap between the poles and rotor surface was analysed.

Reluctance machine belongs to perspective machines and this is the reason why not only construction but also the ways of analysis of its qualities are followed. In this contribution the results of the work devoted to the usage of the finite elements method for the study of qualities of its magnetic circuit and optimalization of our construction are presented. Classical construction of reluctance machine and the latest construction - ALA rotor are compared. Moment M was taken as the comparative criterion.
