Step-by-Step Guide to Simulating a Stepper Motor Based on the 51 Microcontroller Using Proteus (Part 1) – ULN2003 Driver
This article introduces the Proteus simulation system for a 5-wire 4-phase stepper motor driven by ULN2003. The system implements forward and reverse rotation, speed adjustment, and single-step testing functions through button control. It details the structural characteristics (5 leads/4 phase windings) and operating modes (single-phase, double-phase, eight-phase) of the 5-wire 4-phase stepper motor, as well … Read more
