Opis:: A special type of a two-phase permanent magnet stepper motor with asymmetric stator was constructed for the specific purpose. The structural design was based on a modified geometry of standard stator and a functional motor prototype was built. The measurement of the step uniformity reveals irregular step size for half-stepping driver. This paper presents the approach to find proper stator pole dimensions to achieve uniform step in half-stepping regime of permanent magnet stepper motor. The simulation of a magnetic circuit was used. The measurement on the prototype and the simulation of the motor angle for different stator arrangement are presented.

Opis:: The paper presents a simulation model of the hybrid magnetic bearing dedicated to simulations of transient state. The proposed field-circuit model is composed of two components. The first part constitutes a set of ordinary differential equations that describes electrical circuits and mechanics. The second part of the simulation model consists of parameters such as magnetic forces, dynamic inductances and velocity-induced voltages obtained from the 3D finite element analysis. The MATLAB/Simulnik software was used to implement the simulation model with the required control system. The proposed field-circuit model was validated by comparison of time responses with the prototype of the hybrid magnetic bearing.

Opis:: An accurate way to predict the behaviour of an RF analogue circuit is presented. A lot of effort is required to eliminate the inaccuracies that may generate the deviation between simulation and measurement. Efficient use of computer-aided design and incorporation of as many physical effects as possible overcomes this problem. Improvement of transistor modelling is essential, but there are many other unsolved problems affecting the accuracy of RF analogue circuit modelling. In this paper, the way of selection of accurate transistor model and the extraction of parasitic elements from the physical layout, as well as implementation to the circuit simulation will be presented using two CMOS circuit examples: an amplifier and a voltage controlled oscillator (VCO). New simulation technique, electro-magnetic (EM)-co-simulation is introduced.
