About stepper motors

Bipolar Stepper Motor NEMA 17, 145 mNm, 20.5mm, 1A, 3.5V, 1.8 degrees is listed under Stepper Motors — nema-frame steppers, geared steppers and driver modules. Stepper motors are brushless DC electric motors that divide a full rotation into a number of discrete steps, allowing for precise position control without a feedback system. They are commonly used in applications requiring accurate positioning, such as 3D printers, CNC machines, and robotics.
