The present invention relates to a mover for a linear motor comprising: a core part moving along a stator of the linear motor; a coil part coupled to the core part in order to generate thrust; and a cooling ball formed to penetrate the core part in order to cool heat generated from the coil part according to the movement of the core part by outside air, to a manufacturing method thereof, and to the linear motor comprising the same. According to the present invention, the mover can prevent the thrust for moving an object by the heat generated from the coil part from being decreased by being mounted to cool the heat generated from the coil part, can enhance the capacity of cooling the heat generated from the coil part by being mounted to cool the core part directly, and can also improve the cooling efficiency of the core part. |
