•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.
