Transfer Function of Armature Controlled DC Motor: The speed of a dc motor can be controlled by varying the voltage applied to the armature of a dc motor. A separately…
Armature Control Method: The main requirement of this Armature Control Method scheme is a variable voltage supply to the armature whose current rating must be somewhat larger than that of…
Armature Resistance Control Method of DC Motor: In this armature resistance control method of speed control, reduced speeds are obtained by inserting resistance in the armature circuit. It may be…
Armature Voltage Control using Transformer: Variable voltage for the dc motor control can also be obtained by either using an auto-transformer or a Armature Voltage Control using Transformer with tappings…
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…
Speed Control of Three Phase Induction Motor: The problem of speed control of three phase induction motor in particular is of great practical importance. In a number of industries motors…
Booster Speed Control of DC Motor: A booster in series with the armature of the main motor may be employed for varying the voltage across the driving motor. The booster…
Drum Controller for DC Series Motor: DC series motors are often employed on cranes, elevators, tramcars and other applications, where the motor is under the direct control of an operator.…
