Regardless of its seemingly abstract philosophical nature, historically the relation of mind and body has found a surprising variety of forms in the changing “mirror of machines” (Meyer-Drawe, 1996)—perhaps because the “invention” of abstract theorizing and knowledge coincided with the construction of tools and machines. Friedrich Nietzsche brought this articulation of knowledge and machines fa...

This paper introduces the new FundemantalWave library which is included in the Modelica Standard Library 3.2. The presented Modelica package provides models and components of rotating electrical three phase machines. The presented electrical machine models are fully compatible with the original Machines library of the electrical domain but rely on the concept of the magnetic potential and magne...

Condition monitoring of machines working under non-stationary operations is one of the most challenging problems in maintenance. A wind turbine is an example of such class of machines. One of effective approaches may be to identify operating conditions and investigate their influence on used diagnostic features. Commonly used methods based on measurement of electric current, rotational speed, p...

Electric circuit analysis determines the voltage and current distribution in an electric circuit due to applied source voltages or currents. In a static (DC) electric circuit analysis, the voltage and current distribution in an electric circuit is determined that is subjected to applied DC source voltages or currents. In a harmonic (AC) electric circuit analysis, the voltage and current distrib...

Switched Reluctance Machines are receiving significant attention from industries, because of its simple structure; inexpensive manufacturability and reliability make it superior to other electric machines. The objective of this paper is to achieve desired speed performance of 6/4 Switched Reluctance Motor (SRM) with reduced torque ripples. To achieve improved speed performance, PI+FUZZY control...
