Separately
Excited DC motor
•Separately
excited motor have separated field winding means supply to armature is
different and supply to field is different.
•So
any change in armature current (Ia) has no effect on field current (If).
•Direction
of rotation of motor can be reverse by reversing voltage.
•Separately
excited DC motor can operate above base speed.
•Armature
is the rotatory part and field winding is stationary part.
•Motor
speed can be control by varying armature voltage or by varying field voltage
control.
•So
speed control of separately excited DC motor is good.
