💡 What is a stepper motor used for in CNC machines? This handy motor provides precise, repeatable rotation to drive motion systems and positioning stages.

- Used to convert electrical pulses into controlled rotation for accurate positioning
- Handy for X/Y/Z axes in CNC mills, routers, and engraving setups
- Needs a constant-current driver; avoid powering directly from a simple power supply
- Works with common bipolar drive controllers for easy wiring
