Web27 sep. 2014 · When a purely inductive load (zero p.f. lagging) is connected across the terminals of the alternator, current lags behind the voltage by 90°. This means that current will be maximum at zero e.m.f. and vice-versa. Fig. (i) shows the condition when the alternator is supplying resistive load. WebBecause of the complexity of the topic, the following is a simplified explanation of how a four-pole, three-phase AC induction motor works in a car. It starts with the battery in the car that is connected to the motor. Electrical energy is supplied to the stator via the car’s battery. The coils within the stator (made from the conducting wire ...
Alternator - Construction, Working, Types and Applications
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with … Meer weergeven Alternating current generating systems were known in simple forms from the discovery of the magnetic induction of electric current in the 1830s. Rotating generators naturally produced alternating current but, … Meer weergeven A conductor moving relative to a magnetic field develops an electromotive force (EMF) in it (Faraday's Law). This EMF reverses its polarity when it moves under magnetic poles of opposite polarity. Typically, a rotating magnet, called the rotor turns within a stationary … Meer weergeven Alternators may be classified by method of excitation, number of phases, the type of rotation, cooling method, and their application. By excitation There are two main ways to produce the magnetic … Meer weergeven • White, Thomas H.,"Alternator-Transmitter Development (1891–1920)".
