Constant Armature field inductance. (H)
Constant Stator field inductance. (H)
Armature and Stator field resistance.(W)
EMF constant. (V)
Initial conditions for the armature current. (A)
Initial conditions for the stator current. (A)
Special The output of the block is electric torque
Connecting Va and Vf to a voltage block, connects the DC machine into the circuit file.
