DC Motor Braking Methods: The need for electric braking was explained earlier, the motor works as a generator developing a negative torque which opposes the motion. Three types of DC Motor…
Types of DC Motor: The commonly used Types of DC Motor are shown in Fig. 5.1. In a separately excited motor, the field and armature voltages can be controlled independent…
Speed Control of DC Motor: The Fig. 15.38 shows the analog approach to control the Speed Control of DC Motor. A tachometer is used to get the information about the…
Transfer Function of a Field Controlled DC Motor: The speed of a dc motor can be varied by varying the field current. The speed can be increased beyond base speed…
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…
Closed Loop Control of DC Motor: Closed Loop Control of DC Motor - The dynamic behaviour of a system is described by a set of differential equaÂtions. On many occasions…
