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…
Single Phase DC Series Motor Drives: In the Single Phase DC Series Motor Drives the field is connected in series with the armature. The field current is the same as…
Single Phase Separately Excited DC Motor Drives: The circuit arrangement of a Single Phase Separately Excited DC Motor Drives Drives fed from a single phase controlled converter is shown in…
Commutation in DC Motor: Commutation and commutator wear and tear of the dc motor must be given due consideration when the motor operates on solid state converters. Spark-less commutation must…
Torque Equation of DC Motor: When dc voltage is applied to the armature of a dc motor with its field excited by dc, a torque is developed and the armature…
Chopper Resistance in the Rotor Circuit: Speed control by means of slip variation can be achieved by employing a variable resistance Chopper Resistance in the Rotor Circuit. From the equations…
Control of DC Electric Motor: A separately excited DC Electric Motor is very versatile as a variable speed motor. Its speed can be varied by varying the applied voltage to…
Chopper Controlled Resistance: By interrupting the flow of current through a resistance R in a periodic fashion using a switch, the value of resistance can be effectively varied. The interrupÂtion…
