    A microcomputer-controlled testing and performance evaluation scheme for a DC motor is described. A 64 K Z-80-based NEC microcomputer is employed as the main controller of the scheme. The scheme conducts suitable tests, evaluates the performance of the motor and monitors the performance characteristics on a graphics plotter. The usefulness of the scheme is realised by comparing the characteristics... View full abstract»

    Conventional production testing of video cassette recorders (VCRs) uses microprocessor-based test systems as sequence controllers. Program development and debugging using low-level languages is a tedious and time-consuming process. To be effective, test systems must be able to be reconfigured rapidly to meet the requirements for new products and designs in a rapidly changing marketplace. The autho... View full abstract»

    Continual interest in the design and optimisation of permanent-magnet (PM) synchronous motors is being fuelled by rapid developments in permanent-magnet material technology, computation methods for electromagnetic analysis and computer facilities. The article draws attention to the application of the finite-element method (FEM) and interactive computer graphics to the design and optimisation of an... View full abstract»

    Aerodynamics modelling and CAD form a natural partnership. The author discusses how one major CAD/CAM system was used as a pre- and postprocessing tool to an aerodynamic predictions method in a European aircraft company. In addition, the effect of powerful workstations on processing speed and 3-D visualisations and the linking of the 3-D models with stereolithography (to produce an acrylic wind tu...
