Closed Loop Stepper Motor Reference Design With Encoder for Stall-Detection

TIDA-01370

Design files

Overview

This reference design is used for the stall-detection in a stepper motor driven by DRV8880 in the presence of a closed-loop feedback obtained with an optical rotary incremental encoder.  The reference design shows how to detect a stall using a closed-loop algorithm.

Features
  • High resolution positioning system
  • Compact design
  • Closed-loop stepper motor algorithm
  • 5-V encoder output processing
  • 2.0-A full-scale current stepper driver
