GM25-25BY TT Motor 12V GM25-25BY 25mm High Precision Stepper Gear Motor

A stepper motor is a DC motor that moves in steps. With computer controlled steppers, you get very good position and velocity control. Stepper motors are useful for applications that require precise positioning because they have precise repeating steps. Conventional DC motors have little torque at low speeds, while stepper motors have maximum torque at low speeds.
