✍ A stepper motor is a special type of brushless DC motor. Electromagnetic coils are arranged around the outside of the motor. The center of the motor contains an iron or magnetic core attached to a shaft.

✍ Stepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is unwarranted.
 

Please Notice: This shaft is 5mm in diameter.
