“…Fourier expansion of the current sheet is a key step in the analysis of polyphase machines with field harmonics, as emphasized and carried out in chapter 11 of [1]. Formula (4) is a generalization of (5) and constitutes an alternative and easy way to characterize the current sheet harmonics of windings with arbitrary number of phases.…”

Dynamic systems with a finite degrees of freedom number RADOSŁAW ŁADZIŃSKI Taking as a starting point the law of conservation of the total energy of the system, and introducing two basic state functions -the Lagrangian and the Rayleigh function, the general form of the equation of motion for any dynamic system with a finite number of degrees of freedom is derived. The theory is illustrated by considering the rotating -type electromechanical energy converter with six degrees of freedom being the model of all essentially important types of DC and AC machines, including rotating power amplifiers, induction -and synchronous type motors -all of them discussed from both, the steady-state and the transient point of view. In the next part of the paper there is described a simple electric circuit with its model characterized by the holonomic constraints of the velocity-type. Finally, there is presented the kinematics and dynamics of the interesting mechanical system -the gyroscope placed on the rotating Earth.

“…Beginning with the pioneering works of Nikola Tesla and Galileo Ferraris (Tesla, 1888a,b;Ferraris, 1888), much research is devoted to the study of induction machines (see, e.g., (Levine, 1935;Kron, 1951;Adkins, 1957;White and Woodson, 1959;Alger, 1970;Krause, 1986;Ong, 1998;Boldea and Nasar, 2001;Bahram, 2001;Leonhard, 2001;Singh, 2005;Marino et al, 2010;Simion, 2010;Araujo, 2012)). Originally, the theory of induction motors was based on construction of equivalent circuits and their analysis.…”
