Closed Loop Speed Control of Multi Motor Drives: When mechanical part of the load is of large physical dimension it becomes desirable to share the load between several motors. For…
Current Limit Control of Drives: Current Limit Control of Drives scheme of Fig. 3.3 is employed to limit the converter and motor current below a safe limit during transient operations.…
Modes of Operation of Electrical Drive: Three types of Modes of Operation of Electrical Drive: Steady-State Acceleration including starting Deceleration including stopping As we know already, steady-state operation takes place…
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…
Telemetry in Electronic Communications: Telemetry in Electronic Communications consists of performing measurements on distant objects. Although hydraulic or wire circuits may be used for this purpose, this section will deal…
Parametric Amplifier: The parametric amplifier uses a device whose reactance is varied in such a manner that amplification results. It is low-noise because no resistance need be involved in the…
Planar Triode Construction: Planar Triode Construction - A short transit time is essential if grid loss and noise are to be minimized, as is the reduction of internal capacitances and…
