NEMA 17 Stepper Motor (4-Wire, 12V)

Description

NEMA 17 Stepper Motor (4-Wire, 12V)

The NEMA 17 is a high-precision, bipolar stepper motor widely used in CNC machines, 3D printers, and robotic actuators requiring exact rotational positioning.

• Product Description: Unlike DC motors that spin continuously, a stepper motor moves in discrete “steps.” It features two internal electromagnetic coils (hence the 4 wires).

• Key Specifications: It has a 1.8° step angle, meaning it takes exactly 200 steps to complete one full 360° revolution. It typically provides around 4.2 kg-cm of holding torque at 1.2A to 1.5A per phase.

• Visual Identification: A heavy, cube-like motor block (measuring 42mm x 42mm on the faceplate) usually made of black and silver metal, with a 5mm protruding cylindrical shaft and a 4-pin JST connector or four loose wires (often Black, Green, Red, Blue).
