Abstract

The coil-winding process is still largely performed manually, particularly in small-scale industries, assembly workshops, and educational laboratories, resulting in several drawbacks such as reliance on operator skill, relatively long production times, and inconsistent winding quality. This study aims to design and build an automatic coil-winding machine based on an Arduino Nano with a NEMA 17 stepper motor drive. The developed system uses two stepper motors—one to rotate the spool and the other to guide the wire—with the number of windings and wire diameter controlled via input buttons connected to an LCD as the user interface, as well as a limit switch to restrict the movement of the wire-guiding mechanism. Testing was conducted using 0.15 mm diameter enameled wire of Brand A, 0.15 mm of Brand B, and 0.30 mm wire. System performance was evaluated by measuring coil resistance, analyzing the winding distribution at four measurement points (P1, P2, P3, and P4), and performing statistical analysis using mean, standard deviation, and coefficient of variation. The test results showed that all measurement points had relatively small standard deviations, indicating that the resulting winding distribution was uniform, while the accuracy calculations showed values above 98% for all wire variations tested. Based on these results, the developed automatic coil winder is capable of performing the winding process automatically
