  • Thermal Problems in Electrical Machines

    Thermal analysis of electric motors is in general regarded as a more challenging area of analysis than electromagnetic analysis in terms of the difficulties in constructing a model and achieving good accuracy. There are only three types of thermal resistance for conduction, convection, and radiation. Thermal network analysis has become the main tool used by many researchers involved in thermal analysis of electrical machines, both for steady‐state and transient analyses. Network analysis is used to calculate conduction through the electromagnetic structure while computational fluid dynamics (CFD) is used for convection at the surface. The thermal network analysis can be sub‐divided into two main calculation types: heat transfer and flow network analysis. This chapter discusses the main characteristics of analytical software packages used in thermal analysis of electrical machines. Finite element analysis (FEA) is now a standard tool for electromagnetic analysis.

  • Thermal Design

    Knowledge of the temperature distribution in an electric machine is extremely important for its design. This is especially the case when the machine is designed to operate at or near its thermal limits. To determine the temperature distribution in an electric machine, one must have a good estimate of the machine electrical (losses) properties of the cooling fluid and thermal characteristics of the magnetic, conductive, and insulating portions of the machines. First, the distribution of heat sources has to be found based upon the machine geometry and dissipated losses. Typical geometry in which the heat convection takes place in an electric machine is a heated tube through which a cooling fluid is flowing. The heat convection coefficient is dependent on the geometry of surface on which the heat is transferred between the solid medium and cooling fluid, on cooling medium thermal parameters and on its velocity.

  • Porous Media, Permittivity, Fluid Permeability of Shales and Seismic Coda

    This chapter discusses the characteristics of porous media and seismic coda waves. One of the important examples of a porous medium is oil shale. One is the permittivity and conductivity of the porous medium as given by Archie's law. The other is the flow of liquid such as oil through the porous medium as given by Darcy's law and "fluid" permeability, which is different from the "magnetic" permeability concept we commonly use in electromagnetic studies. The study of porous media is closely related to the "percolation theory" and the "fractal". The permeability of a porous medium such as shale is a measure of the resistance to the flow of a fluid through the medium. The chapter shows typical seismic waves observed at the receiver. The study of the P‐coda, S‐coda, and Rayleigh‐coda is critical to the understanding of the total seismic radiation.

  • Thermal Detectors: Mechanisms, Operation, and Performance

    This chapter discusses the mechanisms, operation, and performance of thermal detectors. Thermal detector mechanisms are easily understood and the responsivity easily predicted using only a coefficient that tells how the observable varies with temperature and the formulas of classical thermal engineering. The thermal detectors of importance today are highlighted; they include Golay cells, microbolometer arrays, thermopiles, and ferroelectric and pyroelectric detectors. The Golay cell was a very early, simple thermal detector. Infrared (IR) detection by bolometers and microbolometers depends on the change in electrical resistance of a material as the temperature of the material changes. An important class of thermal detectors depends on the Seebeck effect, the direct conversion of temperature differences between two junctions of dissimilar materials to electric voltages. Pyroelectic and ferroelectric detectors differ from the other thermal detectors in that they depend on a change of the detector temperature, as opposed to the temperature itself.

This means that wet processes and flexible are strongly required and related to the generation change of organic electronics technologies because wet processes and flexible give new value to products and low cost.

  • Recent Advances in Power Semiconductor Technology

  • Textile Antennas for Body Area Networks: Design Strategies and Evaluation Methods

    This chapter presents the design, development, and evaluation procedures for textile antennas. It overviews the types of textiles (conductive and non- conductive) and explains the characterization procedure using a commercial setup prior to the proposal of a systematic antenna fabrication procedure. In experiments, measurement of the reflection coefficient is performed using a vector network analyzer (VNA), whereas radiation characteristics, that is, patterns, gain, and efficiency are evaluated in an anechoic chamber. Antenna performance is assessed in the proximity of either a human user or a phantom and must lead to sufficient design information to guarantee this performance in the simulation-based design process, where the proximity of the human body also has to be taken into account. Finally, the chapter also describes the evaluation methods used for the fabricated antenna prototypes, that is, in terms of reflection coefficient, radiation characteristics, efficiency, and specific absorption rates (SAR).

  • Fault Calculations

    Fault calculations are an important element of power engineering, as they provide information necessary to properly protect the power system, meaning both the equipment comprising the system and the personnel who work on or near it. Fault current calculations can be done for first-cycle current magnitude or interrupting current magnitude. The theory of symmetrical components and the synthesis of sequence networks for three-phase power systems are instrumental for solving most unbalanced problems such as asymmetrical short- circuit and open-circuit faults. Symmetrical components and sequence networks are also vital for understanding the unbalanced operating conditions of an otherwise balanced system, and the behavior and influence of harmonic voltages and currents. A short-circuit fault occurs when one phase is electrically connected, either solidly or through impedance, to another phase or phases and/or ground. The three-phase fault is the only symmetrical short-circuit fault on a three-phase system.
