Torque Speed Characteristics of Induction Motor: From Eq. 1.27 it can be observed that the maximum torque is independent of rotor resistance. However, the slip at which the maximum torque…
DC Motor Speed Control: In the foregoing sections we discussed the torque-speed characteristics of dc motors, bringing out the effects of armature voltage variation and field current on them. The…
Sensors Based Computer Data Systems: This Sensors Based Computer Data Systems describes hardware/software which is commercially available at several levels of completeness, ranging from single board computer "front ends" to…
Measurements of Thickness using Beta Gauge: Beta Gauge - A common and characteristic feature of a radioactive element is that they disintegrate spontaneously to produce fresh radioactive elements called daughter…
Pressure Inductive Transducer: Pressure Inductive Transducer - A simple, arrangement, wherein a change in the inductance of a sensing element is produced by a pressure change, is given in Fig.…
XY Recorder Working: XY Recorder Working - In most research fields, it is often convenient to plot the instantaneous relationship between two variables [Y = f(x)], rather than to plot…
Voltage and Harmonic Control of Inverters: Voltage and Harmonic Control of Inverters - In applying Inverters for motor control both V and f (keeping V/f constant) need to be varied.…
Thyristor Control of Motors: Thyristor Control of Motors - A variety of thyristor control circuitry has been devised for use in motor control depending upon the type of supply (ac/dc)…
