In a separately excited DC motor the motor has separate electrical supplies to the armature winding and field winding which are electrically separate from each other. The motors which are utilized as DC servo motors generally have separate DC source for field winding and armature winding. The control can be archived either by controlling the field current or armature current. 10282015 3 STEADY-STATE MOTOR EQUATIONS 5 x Developed Torque TK T i a T f N-m T motor torque K T torque constant T f motor friction torque i a armature.
