💡 What is a NEMA 23 stepper motor used for in CNC machines and how do torque, current, and step angle affect performance?

Handy for precise control in hobbyist and small-shop CNC setups.

- High torque helps maintain cutting force at low speeds and under load. - Current rating of 3.0A drives stronger torque but requires proper cooling and driver support. - 1.8° step angle (200 steps/rev) enables smooth, accurate positioning, especially with microstepping. - Compact 76mm length and 6.35mm shaft simplify mounting in tight enclosures.
