“…The observed deformations are illustrated by the curve u(t) (see Figure 5). The experiment described in the paper is a continuation of the research aiming to verify measurement methods presented in Zycki (1991Zycki ( , 1995 and Zycki and Sokolnicki (1994) as well as calculation methods of permanent magnets described in Pawluk (1998a, 1998b) and Pawluk and Zycki (2000). Both statements that follow are related, first of all, to the considered magnetic system and to examined magnetic materials.…”

CHAPTER 2 ELECTROMAGNETIC DEVICES Introductory remarksA knowledge of electromagnetism is necessary for understanding the operation of electromechanical converters and electronic systems in general, such as sensors, solid state devices and integrated circuits; also electromagnetic compatibility represents an increasingly important topic. There is a quite high degree of attention to applied electromagnetism due to the increasing number of new topics. One could mention subjects like mechatronics, superconductivity, microelectronics and biotechnologies among emerging fields in which electromagnetism plays an essential role.The complex geometry of devices and the non-linearity of magnetic circuits of electromechanical converters represent unfavourable factors for field calculation. A very small air-gap with a different number of slots in primary and secondary parts of a converter causes high gradients in the field. Therefore, a fine discretization of the field region and, sometimes, the coupling of different methodologies of analysis are necessary. The first group of papers is focused on applying field theory and advanced software to the analysis of steady state and transient performances of induction motors. Computer simulations of starting process are carried out by means of circuit and field method and compared with laboratory tests, leading to the interpretation of phenomena as motor parametric resonance. The field-circuit calculation of output characteristics of a four-speed induction motor is also achieved. Special attention is paid to skewed-cage induction motor for which a quasi-3D finite element method is proposed. The study of anomalies in magnetic field distribution due to broken rotor bars is performed for different load conditions. The use of electromagnetic software linked with electric circuit equations enables determination of motor output parameters for voltage supply. Such an approach leads to an accurate estimation of the magnetic saturation of the core.
