modelPartialAirGapDC
Partial airgap model of a DC machine
Information
Linear model of the airgap (without saturation effects) of a DC machine, using only equations.Induced excitation voltage is calculated from der(flux), where flux is defined by excitation inductance times excitation current. If
quasiStatic == false, the electrical transients are neglected, i.e., the induced excitation voltage is zero.Induced armature voltage is calculated from flux times angular velocity.
