Stepper motors are execution elements with the digital-analogue electromechanical converter function and their use is obvious in numerical control and regulation systems. Stepby-step motors convert directly of the input signal, given in numerical form, in a discontinuous or incremental angular motion. The motion of the set object is quantized in discontinuous displacements, in full consistency with the evolution of discrete command signals. Positioning fidelity made with a step-wise motor will

The stepper motor rotor movement consists of discrete angular displacements, successive, of equal sizes and representing the steps of the engine. Any change in the course of the vessel results in a change in the angular position of the tracking element relative to the meridian.
