Q & A

A 2-phase, 4-wire, 42 stepper motor generally refers to a NEMA 17 stepper motor, one of the most common types used in 3d printers, CNC machines, and robotics.

This stepper motor operates using two electromagnetic coils (phases) and requires a bipolar driver for control. With 4 wires — two per phase — the motor does not have centre taps, distinguishing it from unipolar stepper motors. The wiring typically involves pairs like (A+, A-) and (B+, B-), which must be correctly identified for proper operation. A multimeter can be used to find matching coil pairs by measuring continuity or resistance.
