    This paper sets out to give the reader a flavour of the wide range of design tools and methods presently employed by engineers in the machines industry. From guesstimate to 3D numerical analysis, successful companies must utilise a full spectrum of design approaches in order to compete in today's high pressure, short lead time business environment. Each of these methods is brought to bear with the... View full abstract»

    Most modern large electrical machines are sold subject to a condition in the contract which limits the sound power generated. It is important to a large-machines manufacturer to be able to predict sound power which will be generated by his machine. One the biggest problems in this respect is the determination of the mechanical response of the stator core to electromagnetic forces acting on it. The... View full abstract»

  • Induction motor modelling-choosing the tool to do the job

    Traditionally, induction motors have been modelled using one of two tools-the per-phase equivalent circuit and the two-axis model with pseudo-stationary rotor circuits. The former, which has entirely displaced its analogue equivalent-the circle diagram-has traditionally been used for steady-state calculations, and the latter for dynamic calculations. The computer revolution is changing all that. T... View full abstract»

  • The use of computational fluid dynamics to model the air flow in the end region of a TEFC induction motor

    Publication Year: 1997, Page(s):2/1 - 2/5

    This paper describes how computational fluid dynamics (CFD) can be used to model the ventilation of the end windings in TEFC electric motors. The problems in modelling the complex air flows in the end region of induction motors are described. Suitable approaches to the CFD modelling are then described. The results reveal large variations in the flow patterns and thus identify significant features ... View full abstract»

    Many aspects of electrical machine performance can now be very accurately assessed using numerical computation methods, usually, but not exclusively, finite element analysis. Before the advent of such numerical methods, and the computer hardware capable of supporting them, machine analysis involved the extensive use of equivalent circuits. A transitional era now exists between that of the analytic... View full abstract»

  • IEE Colloquium on Modelling the Performance of Electrical Machines (Digest No.1997/166)

    Publication Year: 1997
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (92 KB)

    This colloquium, which brings together expertise from academia and industry, explores the current machine modelling position from three viewpoints-the electrical engineer, the mechanical engineer, and the industrial research organisation. It will be of interest to those involved in the design of rotating machines and their application together with those in academia who are involved in machines re... View full abstract»
