The invention discloses a linear motor including a stator (2) and a mover (1), a three-phase winding is arranged in the wire embedding groove of the stator (2), the wire embedding groove is arranged in one plane of the stator (2), the three-phase winding is arranged in the same plane with the wire embedding groove, the mover (1) is a flat board parallel to the three-phase winding and a magnetic gap is left between the mover (1) and the surface, having the wire embedding groove, of the stator (2). The linear motor is simple in structure and can directly perform linear motion without converting a transmission mechanism in the middle, so that the system is simplified, the reliability is improved, and the maintenance is easy. The linear speed is not limited because there has no influence of centrifugal force, so that the linear moving speed is high. High precision is guaranteed, for example, the step pitch precision of a linear stepping motor reaches 1 [mu]m. The thrust is large, the reaction speed is high, the acceleration performance is good, the adaptability is high, and the linear motor can be applied to poor environment after a primary iron core is sealed.
