Coefficient of Adhesion in Traction: In Coefficient of Adhesion in Traction, the task of driving equipment consists of pushing the carriage on which it is mounted and pulling coaches and…
Brushless DC Motor Drives(Trapezoidal PMAC): The cross section of a 3-phase 2 pole Brushless DC Motor Drives is shown in Fig. 7.15. It has permanent magnet rotor with wide pole…
Unbalanced Rotor Impedance Operation: Earlier Unbalanced Rotor Impedance Operation were employed for starting and speed control. They are not in use any more. However, a loose contact in the rotor…
Transient Analysis of DC Motor: Starting, braking, reversing speed changing and load changing are the Transient Analysis of DC Motor which commonly occur in an industrial drive. One is interested…
Antenna Tracking System: Having acquired a target through a scanning method as just described, it may then be necessary to locate it very accurately, perhaps in order to bring weapons…
Multicavity Klystron: The design of the multicavity klystron, together with all the remaining tubes described here, relies on the fact that transit time will sooner or later terminate the usefulness…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates…
Amplitude Modulation Theory: In Amplitude Modulation Theory, the amplitude of a carrier signal is varied by the modulating voltage, whose frequency is invariably lower than that of the carrier. In…
