Braking of DC Motors: Controlled slowing or stopping of a motor and its driven load is as important as starting in many applications (e.g. cranes, traction on a slope to…
Ward Leonard Method of Speed Control of DC Motor: Ward Leonard Method of Speed Control of DC Motor is combined armature and field control and is therefore, operationally the most…
Shunted Armature Speed Control: Shunted Armature Speed Control - It is a variation of rheostatic control. As is obvious from Fig. 7.59, the principle used in achieving control is that…
Rheostatic Control Method: Rheostatic Control Method - Series armature-resistance control : Here the applied armature voltage is varied by placing an adjustable resistance Re in series with the armature as…
Starting of DC Motors: At the time of Starting of DC Motors (n = 0), the induced emf of a motor is zero such that the current drawn from rated…
Self Excited DC Generator: Rather than arranging a separate dc source for excitation purposes, practical generators are always excited from their own armature terminals, this method of excitation being known…
Methods of Excitation of DC Generator: The performance characteristics of a dc machine are greatly influenced by the way in which the field winding is excited with direct current. There…
