The step motor is an electric motor used when something has to be precisely positioned, or rotated at an exact angle. As the name says, the stepper motor moves in pitch, that is, it allows you to control your rotation at small angles. Its shaft rotates in strokes MUCFL204 bearings that are controlled by the electronic circuit connected to its input. Typically, pitch motors have windings which, in their simplest form, consist of four coils arranged in the stator at angles of 90 ° relative to one another.

The rotor is a small piece of ferromagnetic material that is a magnet. The stepper motor allows its axis to undergo precise displacements without the need for an external feedback made by some device attached to it. This distinguishes an open system. This open-loop operating characteristic is one of the most important because it allows rotation and stopping at predetermined points. It is necessary for the shaft to rotate a half turn by 180 °, so simply adjust the opening and closing sequence of the logic switches to get the displacement accurately.
