The book offers comprehensive coverage of the broad range of scientific knowledge in the fields of advances in induction and microwave heating of mineral and organic materials. Beginning with industry application in many areas of practical application to mineral materials and ending with raw materials of agriculture origin the authors, specialists in different scientific area, present their results in the two sections: Section 1-Induction and Microwave Heating of Mineral Materials, and Section 2-Microwave Heating of Organic Materials....
Motivated by the need of energy-efficiency improvements, process optimization, soft-start capability and numerous other environmental benefits, it may be desirable to operate induction motors for many applications at continuously adjustable speeds. The induction motor drives can provide high productivity with energy efficiency in different industrial applications and are the basis for modern automation. This book provides an account of this developing subject through such topics as modelling, noise, control techniques used for high-performance applications and diagnostics....
The age of electricity began with the work of Hans
ChristianOersted (1777-1851), whodemonstratedin 1819 that a current-caving conductor could produce a magnetic field. This was the first time that a relationship between electricity and magnetism had been established. Oersted’s work started a chain of experiments across Europe that culminated in the discovery of electromagnetic induction by Michael Faraday (1791-1867) in 1831.
This third edition retains the range of analytical techniques and the structure
of individual chapters of the second edition. However, there are some
significant changes, with the introduction of new topics and some deletions,
to take into account the changing priorities in environmental analysis.
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.
Induction machines have become the staple for electromechanical energy conversion in today’s industry; they are used more often than all other types of motors combined. Several factors have made them the machine of choice for industrial applications vs. DC machines, including their ruggedness, reliability, and low maintenance [1, 2]. The cage-induction machine is simple to manufacture, with no rotor windings or commutator for external rotor connection. There are no brushes to replace because of wear, and no brush arcing...
The evolution of India’s automotive industry is identified to have occurred in four phases. In
the first (1947-1965) and second phase (1966-1979), the important policies identified were
related to protection, indigenisation and regulation of the industry. On the one hand, these
policies helped India to build an indigenous automotive industry, while on the other it led to
unsatisfactory industry performance. In the third phase (1980-1990), the single most
important policy identified was the one with regard to relaxation in the means of technology
In the MEMS industry, systems for deep reactive-ion etching
(DRIE) utilize fast pumping, fast-response mass-flow controllers
inductive coupling of power, and heated chamber and pump lines
that are critical to achieve reliable etch rates. In contrast, we have
achieved 8:1 aspect-ratio PhC structures with 62nm vertica
membrane walls using a standard reactive-ion etching process based
on a sidewall passivation processes. In the remainder of this section
we discuss this fabrication process.
