NEMA 23 Stepper Motors – 112mm – 2.6Nm

A stepper motor or step motor or stepping motor is a brush-less DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.
