Stepper Motor Nema23 2-Phase 0.9 deg 2.8A 57BYGHM604-09

The Stepper Motor Nema23 2-Phase 0.9 deg (model 57BYGHM604-09) is a 2-phase hybrid stepper motor with a 0.9° step angle, which gives 400 full steps per revolution: twice the resolution of a standard 1.8° motor. Rated at 2.8 A per phase in the popular NEMA 23 frame, it is a good choice for CNC machines, laser engravers and other builds that need fine, repeatable positioning.

Tip: Use a stepper driver rated for at least 2.8 A, such as a DM542 or TB6600, and set its current limit to 2.8 A. Microstepping on the driver makes motion smoother and quieter. Never connect the motor coils directly to an Arduino or ESP32 pin.
