Classification of Load Torques: As we know already, the nature of Classification of Load Torques depends on particular application. A low speed hoist is an example of a load where…
Components of Load Torques: Components of Load Torques Tl can be further divided into following components: (i) Friction torque TF : Friction will be present at the motor shaft and also in…
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…
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…
Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters per microsecond. As the object travelled downward,…
Sensors and Transducers: The definition of Sensors and Transducers are follows, The input quantity for most instrumentation systems is nonelectrical. In order to use electrical methods and techniques for measurement, the…
Electrostatic Voltmeters: In Electrostatic Voltmeters fields, the attractive force between the electrodes of a parallel plate capacitor is given by where, V = applied voltage between plates, C = capacitance…
Types of Steel Rolling Mills: Types of Steel Rolling Mills are either hot rolled or cold rolled. These may be either reversing type or continuous type. The motors used for…
