ELECTROMAGNETIC INDUCTION Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. It is described mathematically by Faraday’s law of induction‚ named after Michael Faraday who is generally credited with the discovery of induction in 1831. Electromagnetic induction was discovered independently by Michael Faraday and Joseph Henry in 1831; however‚ Faraday was the first to publish the results of his experiments.[4][5] In

Induction Induction is the process for introducing a new employee to their work environment. It extends from the moment the prospective employee reads the advertisement for the position and fuses with their training and development as a part of the organisation. Why do we need an induction procedure? A proper induction will give both the employees and the organisation the following benefits: (1) It improves the motivation of new employees by helping them (2) quickly assimilate the

The Cross Field Theory of Single Phase Induction Motor The cross field theory of single phase induction motors looks at the induction motor from a totally different point of view. This theory is connected with the voltages & currents that the stationary stator magnetic field can induce in the bars of the rotor when the rotor is moving. Consider a single phase induction motor with a rotor which has been brought up to speed by some external method. Such a motor. Voltages are induced in the bars of

Chapter (9) Single-Phase Motors Introduction As the name suggests‚ these motors are used on single-phase supply. Singlephase motors are the most familiar of all electric motors because they are extensively used in home appliances‚ shops‚ offices etc. It is true that singlephase motors are less efficient substitute for 3-phase motors but 3-phase power is normally not available except in large commercial and industrial establishments. Since electric power was originally generated and distributed

All types of Motor & Generators - AC & DC‚ Starters:Induction Motor (3 Phase):The production of a rotating magnetic field (RMF) is essential for the operation of alternating current (a.c.) induction motors. The speed of rotation of an RMF is known as the synchronous speed and this will be governed by the value of the supply frequency and the number of poles wound within each phase winding. Each of the phase windings are 120 electrical degrees apart. Synchronous speed can be calculated using the following
