The stepper motor is an electromechanical converter that transforms a pulsed electrical signal into a mechanical movement (angular or linear). Its basic structure is in the form of two mechanically separated parts, the stator and the rotor. The electromagnetic interaction between these two parts ensures rotation. In the design of automatic systems, one always seeks to improve the dynamic performances and to minimize the response time. Conventional control algorithms, for example, with integral proportional action, may be sufficient if the requirements on the accuracy and performance of the systems are not too strict. |
