Servo Motor   Servo motor is a device that produces motion in response to a command, and then regulates the speed and direction of that motion in response to feedback. The world of industrial servos is a very diverse one.A servo motor is much more powerful than other motors of the same size.Powerful magnets make servomotors exceptionally quick and accurate. A feedback device called an encoder is built into the servomotor at the back end. Applications of Servo Motor  Cameras  Solar array   Antenna positioning   Robot pets   Textiles   Automatic doors   Remote control toys   Printing presses Servomechanism Servomechanism is an automatic device for controlling large amounts of power by means of very small amounts of power and automatically correcting the performance of a mechanism.   Components of Servomechanism All servomechanisms have at least these basic components:  Controller Command device Error detector Error-signal amplifier The Servomotor Types of Servomec

The programmable logic controller or PLC is a special purpose computer. It has no display, no keyboard, no printer, no hard drive, And hides in the control panel out on the factory floor, but it is still a computer. Initially, the PLC was a replacement for panels of relays, devices that turn on and off. Making a machine run using relays as logic was time-consuming and challenging, and making a change in the logic or the operation of the machine was almost as complicated as starting over. Relays also fail far more frequently than computer components, So that relay logic required more downtime to keeps it running than newer PLC-based controls.  On top of all of that, relays use a lot of electricity, make lots of heat and soot, and take up lots of space. An installed PLC is deceptively simple in appearance. You have a CPU module and input/output devices, referred to as I/O. Sometimes the I/O is part of the CPU, and sometimes it is in other modules. The CPU communicates with the I/O, so in

Electronics E lectronics is a science that deals with electrical devices and circuits that operate by controlling the flow of electrons or other electrically charged particles.   Branches of Electronics Analog Electronics:  Analog electronics deals with analog signals. Analog signals are continuously variable signals. This is in contrast to the digital signals that generally take only two levels. Digital Electronics :  The digital electronics deals with digital signals. Digital signals are the signals that take usually two levels or finite number of levels. Power Electronics:  Power electronics acts as an inter face between the electrical source and electrical load.It applies solid state electronics to the transformation and management of electrical power. Micro Electronics:  Microelectronics is the branch of electronics that is related to the electronic designs at very small scale. Opto-electronics:  Opto-electronics is the branch of electronics that combines objects, that
