Abrégé
(EN)
Provided is a linear step motor, the motor including: a motor housing fixedly mounted at an inner surface of a ring-shaped stator and formed with an opening; a rotor rotatably mounted at a space centrally formed at the stator; a cover member coupled to a bearing to open/close the opening; a nut shaft centrally arranged at the rotor, coupled to an outside of the cover member by passing through a shaft hole centrally formed at an inner ring of the bearing, coupled at a periphery by a magnet and formed with a female screw gear-combined with a lead screw member formed at an inner surface with a male screw; and a fixing unit integrally formed with the nut shaft and fixed to the bearing coupled to the cover member.
