Stepper Motor Nema23 2-Phase 1.8 deg 4.2A 57BYGH686-37E

The Stepper Motor Nema23 57BYGH686-37E is a 2-phase hybrid stepper motor with a 1.8° step angle and a rated current of 4.2 A per phase. Its NEMA 23 frame (about 57 mm square) is larger and stronger than the NEMA 17 used in most 3D printers, so it is a common choice for CNC routers, laser machines, linear stages and other machines that need more torque.

• 1 × NEMA 23 stepper motor 57BYGH686-37E

Tip: Use a stepper driver rated for at least 4.2 A per phase, such as a DM556-class digital driver; small drivers like the A4988 or DRV8825 cannot supply this current. Set the driver's current limit to the motor rating, and use a higher supply voltage within the driver's limit, such as 24–48 V, for better torque at speed.
