It allows the students performing study and experimentation concerning the driving of a step motor, unipolar or bipolar. The rotation can be performed with increments of a single step or with continuity, at a variable speed. This board is designed to provide a valid support for the study of the operation and of the application criteria of these important electro mechanical components. Position and direction are indicated by a disk. An LCD display allows showing the number of steps, the number of turns, the rpm, the rotation direction and the selected parameters of the controller.
Experiments:
Study of an incremental position encoder
Variable speed rotation control
Inversion of the rotation direction
Analysis of the control criteria and of the power modules
