This bipolar Nema 17 stepper motor with step angle 1.8deg and size 42x42x38mm. It has 4 wires, each phase draws current 1.5A, with holding torque 42Ncm.
***On some systems, the middle 2 wires on the motor side are swapped. This is easy to fix by slightly prying back the white nubs and swapping the wires. Otherwise they work fine.***
Make sure the motor connect to a constant current or chopper drive controller before you test motor. Connecting the motor directly to a power supply will destroy the motor.
