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 […]

Speed Torque Characteristic of Separately Excited DC Motor

Speed Torque Characteristic of Separately Excited DC Motor: The circuit equation of a Speed Torque Characteristic of Separately Excited DC Motor whose armature, having a total of Z con­ductors, is wound for 2P poles (the brushes divide the winding into 2a parallel paths), is Where E is the back emf of the armature given by […]

Characteristics of DC Motor

Characteristics of DC Motor: Characteristics of DC Motor are of the rotating armature type. The armature winding is a closed winding through the commutator. The armature is supplied through the brushes which are placed along the neutral axis on the commutator. The field system is stationary. The mmf produced by the field is along the […]
