[0025] A plurality of extension portions 63 are arranged between the two connection portions 61 of each of the silicon steel sheets 6 along the length direction of the silicon steel sheet 6, so that the mover tooth portions 31 are formed on the stacked mover core 3 by the extension portions 63.

[0026] The above embodiment is further explained as follows: The linear motor mover is a flat rotor of a common motor, which is converted into an open magnetic field environment, so that the mechanical energy of linear motion can be directly converted from electrical energy, and through the combination of the linear motor mover and the stator, the transmission device without intermediate conversion mechanism can be directly realized to achieve controllable linear motion.
