    These papers describe electric circuit analogs for the 2-dimensional magnetic fields of synchronous machines. Although finite difference solutions of the differential equations are introduced to establish the mathematics, equivalent circuits are also deduced from elementary field and circuit theory familiar to electrical engineers. A simple resistive circuit is constructed to represent the static ... View full abstract»

    PART I [1] of this series established a simple resistive analog to represent the static magnetic field. It was shown that by the use of a dc constant current network the magnetic vector potential solution of static field problems could be obtained including the correct boundary and internal field relations. Mention was made of the contribution of Roberts [2] in regard to the use of the RC analog t... View full abstract»

  • A New Theory of Electric Machines

    A theory of commutating machines is presented. Besides giving a new and interesting explanation to the commutation process from both field and geometric points of view, it enables the equations to be derived by a simple application of a differential operator to the coenergy function. This differential operator is the long sought-for extension of Lagrangian theory to the commutating machine. The th... View full abstract»

    The synchronous machine can be represented by a simple and easily surveyed block diagram from which can be derived all possible transfer functions. Because of the introduction of complex representation of input and output quantities, this block diagram is valid for the positive as well as for the negative-sequence system of the stator. These transfer functions for the positive and negative sequenc... View full abstract»

    In this paper, a method is provided for finding the magnetic fields in dc machines on-load and overloads. Mathematically, the problem is that of solving a quasi-Poissonian equation through use of a modified relaxation method. The differential equations are first replaced by difference equations; this constitutes a set of algebraic equations which are solved by a procedure consisting of relaxation ... View full abstract»

  • An Analysis of the Resistance of Sliding Electrical Contacts

    Publication Year: 1966, Page(s):967 - 974
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3539 KB)

    This paper presents the conception of the sliding contact area as a velocity-dependent parameter and develops a method of assessing the variation of contact resistance with sliding velocity. Results of experimental work on sliding point contacts between carbon sliprings and carbon brushes are presented in the form of resistance-velocity characteristics. The percentage variation of contact area wit... View full abstract»

    To avoid instability of single-unit frequency convertors with distributed copper rotors described by the author [1], a variation of the machine is described here. The basic principle of power exchange between two windings of different pole numbers has been retained. In this machine the rotor iron is shaped to produce the necessary dissymmetry. This eliminates the discontinuity in the generated vol... View full abstract»

    The authors examine the problem of coordination between the open-gap insulation of a switch and its insulation-to-ground, with respect to switching surges. The results of a series of tests performed on an EHV switch with varied gap spacing and varied stack height are examined, and a method for designing the open gap of a switch is accordingly proposed. From the same point of view, "anomalous" flas... View full abstract»

    The operating practice and experience of electric utility companies varies widely in the matter of interrupting with air break switches, small magnitudes of magnetizing, charging, and loop currents. A questionnaire survey was made of 71 utility companies. Observations and graphic and tabulated summaries of their practices and experience are presented for the information and guidance of the industr... View full abstract»
