FPGA Prototyping Using the STEMlab Board With Application on Frequency Response Analysis of Electric Machinery

This paper presents a complete procedure on prototyping using the FPGA of the STEMlab board and is intended to serve as a guide for developers, students and researchers interested in speeding up their projects and experiments. Due to the reconfigurability of its internal circuitry, being as simple as a code modification (using hardware description language), FPGA technology allows testing of several controller topologies and/or parameters without the need of any physical change at hardware. This feature allows a much faster development cycle of either commercial products or academic experiments. Besides the reconfigurability of the FPGA, the STEMlab board also offers the advantage of several peripheral already available, which includes, among others, high speed analog-to-digital and digital-to-analog converters, Ethernet communication and a dual-core ARM processor capable of running a Linux operating system. In this paper, a didactic method of use of this board is presented, from getting started to a complete academic and industrial application: detection of early damage on an induction motor using frequency response analysis.

RELATIVISTIC PLANE WAVE ANALYSIS OF A CARTESIAN INDUCTION MOTOR STRUCTURE

ABSTRACT Analysis of electrical machinery is usually carried out with the aid of lumped-parameter techniques; at the same time, a distributed-parameter model is of theoretical interest as it provides insight into the behavior of the magneto-electric device without any restriction imposed upon supply frequency, width of air gap or even velocity. An analysis which takes into account the finite velocity c of a plane electromagnetic wave in vacuum, of necessity resorts to restricted relativity, which has the great advantage of leaving the field equations form-invariant. In the present paper such an approach is briefly outlined.

Computer-aided design and analysis of electrical machinery and devices (abstract)

Recent years have witnessed a growing demand for economical and energy efficient designs of electrical machines and their reliability in operation. Improved performance prediction at the design stage helps achieve some or all of these objectives in a cost effective and efficient manner. With the advent of digital computers, it has become possible to achieve this goal with a high degree of accuracy and minimal turn around time. A design study for tradeoffs of cost versus efficiency and reliability requires the use of sophisticated computational tools. Traditionally computer programs have been designed with a view to provide the user multiple options in terms of analyses, data manipulation, and post-processing of results. These codes have tended to be large and have been generally implemented in a batch mode with long turn around times. In this paper, an alternative approach to the traditional computer analysis of electric machines is presented using an interactive user-friendly software package. A finite element electromagnetic analysis program is considered, as it is one of the more significant and difficult to implement codes required frequently for design use. The advantages of interactive and generalized engineering software for the application mentioned above are examined. The detailed steps of engineering design analysis of a rotating electrical machine carried out with the help of an integrated software is described.

Three-Dimensional Magnetostatic Field Analysis of Electrical Machinery by the Finite-Element Method

Modern electrical plants and machinery are required to operate at high-power density levels at minimum cost and improved efficiency with a high degree of reliability. Such stringent requirements necessitate a high degree of accuracy in predicting machine performance at the design stage, for which sophisticated analytical tools are essential. In this paper, a rigorous three-dimensional magnetic field analysis based on the finite element method is presented. The correct choice of the vector potential solution is established and it is shown that the variational formulation yields an energy-related functional associated with the vector Poisson equation which, when minimized, results in the true solution to the field problem. The analysis developed is applied to illustrative geometries; the principal amongst these being a two-winding transformer and a segment of a turbine generator.

Some remarks on the analysis of electrical machinery in rotating frames of reference

Electrical machines are analysed at hand of Maxwell's equations. In their regular form, these equations hold in inertial frames of reference onlyk whereas a rotating rotor obviously does not fall within this category. Some of the issues involved in this contradiction are outlined.

Finite element analysis of electrical machinery and devices

Design optimization and reliability assurance of electrical machinery and devices require accurate prediction of the magnetic field distribution in their active region. The finite element method offers a stable numerical solution technique with a high degree of precision. This method is based on formulating the partial differential equations of the magnetic field problem in variational terms and minimizing the associated functional by a set of trial functions. This paper describes the application of finite-element analysis to electric, magnetic and eddy-current field problems in rotating machinery, static apparatus, and devices. Some of the areas surveyed are magnetic fields in synchronous machines, dc generators, transformers, eddy-current problems in conducting media, and electrostatic applications.
