  • This new edition of Electronic and Electrical Servicing refl ects the rapid changes that are taking place within the electronics industry. In particular, we have to recognise that much of the equipment that requires servicing will be of older design and construction; by contrast, some modern equipment may require to be replaced under guarantee rather than be serviced. We also need to bear in mind that servicing some older equipment may be totally uneconomical, because it will cost more than replacement....

  • Preface The industrial brushless servomotor has developed through a remarkable combination of mechanical, electrical, power electronic and microelectronic technologies, and both the operation and application of the motor rely on many interdependent factors. I have tried to cover the fundamentals of the subject in a logical manner, taking a step-by-step approach, describing first the construction of the brushless machine itself and how it works, second, how the current is supplied, third, how the motor behaves when it is loaded and finally how it is rated and selected for a particular duty.

  • Electrical consumption, especially direct or variable frequency currents, has strongly increased over 50 years in industry. This situation explains the growth of power electronics. At the beginning, when rectifiers replaced DC machines, only diodes and thyristors were used. Then power transistors appeared and enabled the extension of smaller power applications for domestic use. New research topics were developed around converters and power devices.

  • The use of a combustion engine to motivate a car has been questioned in recent times due to the increasing concern of warming. As a result of this, the concept of driving a car with an electric engine has become of particular interest. Dr. Geoff Walker and his PhD students are working on the creation of the Universitys own electric car. This thesis project is focused on deriving a control scheme to drive an induction machine that could be applied to the electric car.

  • The most popular of the rigid reinforcements for printed wiring boards is woven E-glass (electrical-grade glass) fabric. These fabrics are constructed to meet weight, thickness, strength, and cost objectives. The woven fabric is used in many industries as reinforcements for thermoplastic and thermosetting plastic parts. Thermosetting laminates are particularly enhanced by the properties of the glass fabric.
