Working Principle of Alternator; 

 TheWorking Principle of Alternator is very simple. It is as basic principle of DC generator. Also depends on Faraday's law of electromagnetic induction that says the current is induced in the conductor Within the UN magnetic field when there is relative movement between said driver and thefor Understanding Working alternator will Thinking Time Only A rectangular placed between two opposite magnetic poles as shown above.
OPERATION principle alternator
Say esta simple loop ABCD turn can rotate against the ab axis. Suppose Que esta loop begins turning clockwise. After 90 ° of rotation of the side AB or AB loop driver Comes Before Polo S and driver CD Comes Ahead of N-pole. IN THIS POSITION IS tangential motion of the conductor AB perpendicular to the lines of magnetic flux from N to S pole. At Both Flow Rate cut BY driver AB is here And That The Maximum Flow Cut Habra A current induced in the conductor AB and address of the induced current can be determined by rule of the Right Hand Flemming. Agree with the Directorate of standard esta esta current Sera A to B. At The Same Time Driver CD under ESTA pole N and here Also if we apply the rule Fleming continues right hand get the SENSE of the induced current and be a starting C A D

Now, after turning to the Right of a 90 ° turn ABCD arrives in vertical position, de este forms a continuation. In this position the tangential motion of the conductor AB and CD is only to Parallel Lines Magnetic flux, of so much of by not cutting Flow Habra That is not current in the conductor. De While The ABCD your Time Comes from the horizontal position to the vertical position, the angle between the lines flow and direction of movement of the driver are reduced from 90 ° to 0 ° and in consequence the current induced in the loop a zero of its maximum value is reduced.
After another Clockwise rotation of 90 ° around again come to the horizontal position and driver here AB under ESTA pole N and the this CD under S-pole, and if we return here one APPLY Right-hand rule of Flemming, LET'S More than current induced in the conductor AB, is from the point B aay the current induced in the CD driver is D to C.

As in this position the shift comes from bathroom horizontal position do vertical position in Stream Drivers Do Maximus comes a value of zero. That means the current is flowing in the CLOSING Your Time From point B to A, A to D, D to C and from C to B. Justo inverse of the above horizontal when the stream flowed As A → B → C → D → A. While turning more upright position of the current income is reduced back to zero. So What If the rotation continues turning the current alternative continually shift its direction. During each complete revolution of the turn, the current in the Vuelta gradually reaches its maximum value is reduced then a zero again and THEN Treated for Maximum value, but in the opposite direction and again This Is zero. De esta Way Stream Full One way to complete sine wave during each revolution around 360 °. THEN WE Spinning Seen As An alternating current is produced in a twist Within the UN magnetic field. From this, now let's come to the Principle of Real OPERATION alternator.
Now cut the loop and connect both ends with two rings collectors and stationary brush is placed on each slip ring. If we connect two terminals Of An external load Estós two brushes, get An alternating current in the load. This is our basic model of the alternator.

Having Understood the basic principle alternator, now we'll have an idea of your Basic Operating director of the UN Practical alternator. In Discussion of Basic Working alternator, it is considered that the magnetic field is stationary and Hardware (Armor) Turning THIS. But usually in Practice alternator construction, Hardware son stationary armature and field MAGNETS rotate Between Them. The alternator rotor from the UN or UN esta synchronous generator mechanically coupled to the shaft or the turbine blades, which being and spins a synchronous speed Ns SOME low mechanical strength results in cutting the magnetic flux Leads stationary armature housed in the stator. As a direct consequence of esta Flow Cut An induced emf and current begins to flow through conductors Frame It Flow First an Address To The First Half Cycle and THEN in the Other Direction paragraph El Segundo para Each cycle means winding with a Definite Time lag of 120 °, the space DUE Displaced Provision of 120 ° Displays Between Them As the figure below. This phenomenon results in particular in the Flow of Energy 3φ alternator Out Of That THEN Transmits the para Stations Distribution Domestic and industrial uses.
