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 Motions such as rotational and…
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 speed is considered positive when…
Torque Equation of Motor Load System: A motor generally drives a load (machine) through some transmission system. While motor always rotates, the load may rotate or may undergo a translational motion. Load speed may be…
Power Budget in Optical Fiber: The term Power Budget in Optical Fiber is the relationship between the power losses in fiber links and associated equipment and the available input power to the system. The available…
Fiber Optic Testing: The Fiber Optic Testing focuses primarily on the processes and equipment used during and after the installation of fiber optic cables and their associated equipment. The Fiber Optic Testing is performed by…
Installation of Fiber Optic Cable: Because of their light weight and flexibility, fiber cables are in most cases easier to install than their copper counterparts. There are some concerns, however, that must be faced by…
Fiber Optic Components and Systems: The Fiber Optic Components and Systems can be divided into subgroups, the source, the link, and the detectors. We will now explore the makeup and role of each of these…
Fiber Losses: Energy losses and signal degradation in Fiber Losses can be attributed to a variety of causes, some of which have been mentioned previously. To add to this list: 1. Light scattering (Rayleigh Scattering)…
Optical Fiber Classification: The Optical Fiber Classification of light transmission through a glass fiber depend on many factors, for example: The composition of the fiber The amount and type of light introduced into the fiber…
Construction of Optical Fiber Cable: The manufacture and Construction of Optical Fiber Cable are somewhat complicated: In simple terms, a highly refined quartz tube that will eventually be filled with a combination of gases (silicon,…
