Modelling a shunt motor¶
This example shows the modelling of a shunt motor. In the shunt motor, the field and armature windings are connected in parallel. The parameters of the equivalent circuit are the armature resistance $Ra = 110 Ом$, the field resistance $Rf = 2,46$ Com and the inverse EMF coefficient $Laf = 5,11$. The inverse EMF is defined as $Laf*If*Ia*w$, where $If$ is the excitation current, $Ia$ is the armature current, and $w$ is the rotor speed in rad/sec. The inertia $J$ of the rotor is 2.2e-4 $кгм^2$, and the damping B of the rotor is 2.8e-6 $Нм/(рад/с)$.
