This model represents a Nonlinear model of a permanent magnet DC motor with a
rack-and-pinion mechanical drive. Motor icon is shown in Fig. 1. Terminals A and
B are the electrical nodes. Node C is a linear motion node representing the tip of the
moving rack. The rack-and-pinion drive dimensions are such that when the rotor turns by
on radian the rack moves by one meter. The rack moves in the positive direction when
the voltage at node A with respect to node B positive. In this model, linear magnetic
circuit is considered without magnetic saturation and dissertation.
