Basic Principle Of Alternator

Image
A.C. generators or alternators (as they are usually called) operate on the same fundamental principles of electromagnetic induction as d.c. generators. They also consist of an armature winding and a magnetic field. But there is one important difference between the two. Whereas in d.c. generators, the armature rotates and the field system is stationary, the arrangement in alternators is just the reverse of it. In their case, standard construction consists of armature winding mounted on a stationary element called stator and field windings on a rotating element called rotor. The details of construction are shown in Fig. alternator The stator consists of a cast-iron frame, which supports the armature core, having slots on its inner periphery for housing the armature conductors. The rotor is like a flywheel having alternate N and S poles fixed to its outer rim. The magnetic poles are excited (or magnetised) from direct current supplied by a d.c. source at 125 to 600 volts.

AUTOMATIC NIGHT LAMP WITH MORNING ALARM USING MICROPROCESSOR

AUTOMATIC NIGHT LAMP WITH MORNING ALARM USING MICROPROCESSOR INTRODUCTION: This Project "Automatic Night Lamp with Morning Alarm" was developed using Microprocessor. It is the Heart of the system. The sensors are made with help of LDR which are Light  Dependent  Resistors,  whose  Resistance  is  inversely proportional to the Light falling on it. The LDR converts the light energy into electrical energy and this variable electrical energy was converted into digital signal (0 or 1) by using the timer IC555. The Timer IC output goes low when light falls on the LDR and the timer IC output goes high when the LDR was placed in dark. OBJECTIVE: 1) Tolearn and develop knowledge in designing the application by using the microprocessor. 2) Tolearn how to write an assembly language and combining with the hardware. 3) Tolearn how make a full report of project Microprocessor Also check our small business blog startuphq.in SYSTEM DESCRIPTION: In  thi...
