Different Types of DC Distributors: Different Types of DC Distributors - In the beginning of the electrical age, electricity was generated as a direct current and voltages were low. The…
Comparison of AC Transmission and DC Transmission: The electric power can be transmitted either by means of d.c. or a.c. Each system has its own merits and demerits. It is,…
DCS System: A DCS System is preferred over a central computer system for the following reasons. Central Computer System (CCS) exposes the plant to the risk that the system might fail.…
AC Resistance and DC Resistance Relation: Though the contribution of line resistance to series line impedance can be neglected in most cases, it is the main source of line power…
Compensating Winding in DC Machine: Compensating Winding in DC Machine - It was seen from earlier section, that armature reaction causes the flux density wave to be so badly distorted…
Armature Reaction in DC Machine: When the armature of a dc machine carries current, the distributed armature winding produces its own mmf (distributed) known as armature reaction in DC Machine.…
EMF and Torque Equation of DC Machine: EMF and Torque Equation of DC Machine - It was shown in Sec. 5.2 (Fig. 5.14 (a)) that in a dc machine the…
Introduction of DC Motor: Introduction of DC Motor is constructed in many forms and for a variety of purposes, from the 3-mm stepper drawing a few ÎĵA at 1.5 V…
