Step Motor Control

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
Full step or half step
Analysis of the operation of a step motor.
