Steady State Stability of Drive: Equilibrium speed of a motor-load system is obtained when motor torque equals the load torque. Drive will operate in steady-state at this speed, provided it…
Time and Energy Loss in Transient Operations: Starting, braking, speed change and speed reversal are transient operations. Time and Energy Loss in Transient Operations can be evaluated by solving Eq.…
Motor Design Parameters: Different parts of a load may be coupled through different mechanisms, such as gears, V-belts and crankshaft. These parts may have different speeds and different types of…
Four Quadrant Operation of Motor Drive: For consideration of Four Quadrant Operation of Motor Drive, it is useful to establish suitable conventions about the signs of torque and speed. Motor…
Fiber Optics History: Fiber Optics History - In 1870 John Tyndall, a natural philosopher living in England, demonstrated one of the first guided light systems to the Royal Society. His…
Color Picture Tube Working: A Color Picture Tube Working requires correct sweep currents, input voltages and drive voltages. Having said this very quickly, it is now a good idea to…
Color TV Transmission and Reception: If color TV had come before monochrome TV, the system would be far simpler than it actually is now. Since only the three additive primary…
Monochrome Television Receiver Block Diagram: Monochrome Television Receiver Block Diagram as shown in Figure 17-9, TV receivers use the superheterodyne principle. There is extensive pulse circuitry, to ensure that the…
