Transfer Function of Armature Controlled DC Motor

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 excited dc motor with variable armature voltage finds application as a drive motor in a variable speed drive. The variable armature voltage is provided by […]

Single Phase DC Series Motor Drives

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 the armature current. The schematic of a Single Phase DC Series Motor Drives fed from a phase controlled converter is shown in Fig. 4.62. DC […]
