PURPOSE: A stepping motor is provided to prevent the deterioration of the motor performance in advance by rapidly radiating high heat generated during the operations of a stator and a rotor. CONSTITUTION: A coil(110) is wound on the inside of an upper stator(100), yokes(120) are alternately arranged on the upper and lower sides of the upper stator(100) to be opposite to a rotor(300). A lower stator(200) is closely mounted on the lower side of the upper stator(100) and has the same structure as the upper stator(100). The upper and lower stators(100, 200) are fixedly incorporated through upper and lower plates(400, 500) mounted on the upper and lower side of the upper and lower stators(100, 200). A heat radiator radiates high heat generated when a current is applied to the coils(110, 210).
