Air Gap DC

Linear air gap model of a DC machine

 Description The linear model of the air gap of a DC machine, models the air gap without saturation effects. Induced excitation voltage is calculated from $\mathrm{der}\left(\mathrm{flux}\right)$, where $\mathrm{flux}$ is the excitation inductance multiplied by the excitation current. The induced armature voltage is found by multiplying $\mathrm{flux}$ by angular velocity.
