Voltage regulation of Alternator by EMF method

 · The voltage regulation of alternator by EMF method involves the EMF quantities of all the armature parameters (armature resistance, Armature leakage reactance, armature reaction). The drop due to armature reaction is not considered, because it does not occur due to any of the physical element but due to interaction of armature flux with main flux.

Alternator Stators

 · Stator Frame and Rotor Construction. The stator frame is used to hold the armature windings in alternators, and in case of larger diameter alternators (which are slow speed) the stator frame is cast out of sections and there are holes for ventilation in the casting itself. The recent trends towards such stator construction are more in favour of ...

Parallel Operation of Alternator | Electrical4U

 · October 25, 2020. February 24, 2012. by Electrical4U. Alternator is really an AC generator. In alternator, an EMF is induced in the stator (stationary wire) with the influence of rotating magnetic field (rotor) due to Faraday''s law of induction. Due to the synchronous speed of rotation of field poles, it is also known as synchronous generator.

Effect of Change in Excitation on an alternator connected ...

The overexcited alternator will supply lagging current (and hence lagging reactive power) to the infinite busbars. This action can be explained by the m.m.f. of armature reaction. When the alternator is overexcited, it must deliver lagging current since lagging current produces an opposing m.m.f. to reduce the over-excitation.

Working Principle of an Alternator | Electrical4U

 · by Electrical4U. The working principle of an alternator is very simple. It is just like the basic principle of DC generator. It also depends upon Faraday''s law of electromagnetic induction which says the current is induced in the conductor inside a magnetic field when there is a relative motion between that conductor and the magnetic field.
