Electrical Machines I Prof. Krishna Vasudevan‚ Prof. G. Sridhara Rao‚ Prof. P. Sasidhara Rao 2 Basic Principles As mentioned earlier the transformer is a static device working on the principle of Faraday’s law of induction. Faraday’s law states that a voltage appears across the terminals of an electric coil when the flux linkages associated with the same changes. This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced

Frictionless Compressor Technology Compressors that run on frictionless bearings are an enticing prospect. Here the the compressors operate without metal-to-metal contact by levitating the compressor shaft in a magnetic field. Thus the need for an oil management system is eliminated. Such type of compressors are designed to take advantage of the magnetic bearing technology. Magnetic bearings: The lubricated bearings in ordinary systems is replaced by a digitally controlled magnetic bearing system

Physics E=mc2 The film starts out by describing how the equation E=mc² came about explaining each variable and the scientist’s whose ideas helped develop E=mc². In the movie E as in energy was explained first. Before energy’s discovery people thought that it was a composition of random forces acting upon someone or something that created movement. Michael Faraday went from being a blacksmith and became a scientist after being inspired after attending a speech from his idol Sir Humphrey Davy

HOW AN ELECTRIC GENERATOR WORKS Electrical generators by definition are devices that convert mechanical energy into electric energy. The mechanical energy in turn is produced from chemical or nuclear energy in various types of fuel‚ or obtained from renewable sources such as wind or falling water. Steam turbines‚ internal-combustion engines‚ gas combustion turbines‚ electric motors‚ water and wind turbines are the common methods to supply the mechanical energy for such devices. Generators

Kerosene oil lanterns and gas lamps are now things of the past. We now light our lamps with electricity. Switch on the button and there is the day-like light even in the darkest night. In summer seasons electric fans‚ air conditioning plants are used to provide us with cool atmosphere. In winter‚ heating plants are used to keep the room warm. Electric bells‚ press and stove are things of every-day use. People keep refrigerators in their homes to keep their food in a fresh condition. Indeed electricity

A direct current (DC) motor is a fairly simple electric motor that uses electricity and amagnetic field to produce torque‚ which turns the motor. At its most simple‚ a DC motorrequires two magnets of opposite polarity and an electric coil‚ which acts as an electromagnet. The repellent and attractive electromagnetic forces of the magnets provide the torque that causes the DC motor to turn. If you’ve ever played with magnets‚ you know that they are polarized‚ with a positive and a negative side. The
