Power ICs odften have to
drive non linear, reactive or complex loads. Simulating the device with
the load sometimes is far from trivial because there are no reasonable
descriptions of the load in a simulation language compatible with the design
The load models presented here are far from perfect but may give some starting point how th describe at lease a small signal operating point.
To give an example of the simulated movement of the rotor the following graph displays the ideal step (brown), the rotation of the rotor (green) and the movement of an elastically coupled load (blue).
