The Air Gap DC component models the air gap of a DC machine, without saturation effects. Induced excitation voltage is calculated from the derivative of the magnetic flux, where flux is the excitation inductance multiplied by the excitation current. The induced armature voltage is found by multiplying flux by angular velocity.
