How to identify stepper motor wires and coil pairs (A+/A-, B+/B-) without confusion! In this video, I show 3 simple methods to test and connect stepper motors like NEMA 17, NEMA 23 with Arduino or CNC drivers.
✅ Method 1 – No tools: Find pairs by feel/resistance
✅ Method 2 – Multimeter continuity test
✅ Method 3 – Datasheet check & Arduino driver test
You’ll also see what happens if you swap pairs or polarity so you can connect stepper motors correctly to a driver. Perfect for 3D printers, CNC machines, robotics, and DIY electronics.
