                               Stepper motors

                                       Stepper motors may be used for locomotion, movement, steering,
                                       and positioning control. These motors are used as integrated com-
                                       ponents in many commercial and industrial computer-controlled
                                       applications. For home personal computer (PC) users, stepper mo-
                                       tors can be found in disk drives and printers.

                                       Stepper motors are unique because they can be controlled using
                                       digital circuits. They are capable of precise incremental shaft rota-
                                       tion. This makes stepper motors ideal for rotary or linear positioning.
                                       Because stepper motors are widely used in industry, they come in a
                                       variety of shapes, sizes, and specifications (see Fig. 4.8A).
