Abstract:
1. A step motor including a stator unit having first and second stators which butt against and are coupled to each other and each have a bobbin receiving a coil that generates a magnetic force when external power is applied thereto and a yoke attached to the bobbin, a rotor unit which is inserted into an inside of the stator unit and has a magnet mounted to an outer circumference of a rotating shaft, thus generating a rotating force, and a casing unit which is provided around an outer circumference of the stator unit to protect and cover the stator unit, wherein the first and second stators comprise terminal blocks which protrude vertically from upper ends thereof, and the terminal block of the first stator is spaced apart from the terminal block of the second stator when the first and second stators butt against and are coupled to each other.
