A DC Machine is an electromechanical device that enables the conversion of energy between mechanical and electrical forms. When it operates as a generator, it transforms mechanical input power into electrical output power. When functioning as a motor, it performs the opposite conversion – turning electrical energy supplied to it into mechanical motion. DC machines

An AC Servo Motor is a specially designed two-phase or three-phase induction motor used in servo-mechanism and closed-loop control systems where precise control of position, speed, and acceleration is required. Unlike ordinary induction motors, an AC servo motor is optimized for fast dynamic response, low inertia, high starting torque, and accurate controllability, making it highly

An Isolation Transformer is a specially designed transformer used to electrically isolate a device or electrical system from the main power supply while still allowing AC power to be transferred magnetically. Unlike ordinary power transformers, an isolation transformer has a 1:1 turns ratio and does not step voltage up or down. Its primary purpose is

Three phase voltage is the most widely used AC power system in the world. It forms the backbone of electric power generation, transmission, distribution, and industrial applications. Compared to a single-phase supply, a three-phase system delivers higher efficiency, smoother torque, lower conductor cost, and constant power transfer. Because of these advantages, almost all industrial machinery,

A rheostat is an important electrical component widely used in power and control circuits. It is mainly used to control current in a circuit without interrupting the supply. Rheostats are commonly found in laboratories, industrial equipment, motor control systems, and high-power applications.   What is a Rheostat? Definition: A rheostat is a type of variable

A carbon composition resistor is one of the oldest and most widely used types of fixed resistors in electrical and electronic circuits. Due to its simple construction, low cost, and wide resistance range, it has been extensively used in early electronic equipment, radios, amplifiers, and general-purpose circuits. Although modern resistors such as carbon film and

Linear Variable Differential Transformer (LVDT) is one of the most popular electromechanical transducers used for precise measurement of linear displacement. It converts small mechanical movement of a soft iron core into a proportional electrical voltage. Because of its high accuracy, reliability and frictionless operation, the LVDT is widely used in industrial control, automation, aerospace, power

Definition of Solar Lamp A solar lamp (or solar light) is a lighting device that uses solar energy instead of grid electricity. During the day, a solar panel converts sunlight into electrical energy and stores it in a rechargeable battery. At night, an electronic controller supplies this stored energy to a high-efficiency LED lamp, providing
