Moving magnet type linear oscillation motor without inner stator

The invention discloses a moving magnet type linear oscillation motor without an inner stator. The moving magnet type linear oscillation motor without the inner stator comprises stator cores and a permanent magnet arranged inside the machine shell, wherein the stator cores are C type cores, the upper tooth part and the lower tooth part of each C type stator core form an N pole and an S pole respectively after an armature winding is arranged, the permanent magnet is arranged between the two stator cores, tooth parts of the two stator cores right face each other, the N pole and the S pole of the two stator cores are opposite, the two poles of the permanent magnet right face the upper tooth parts of the two stator cores and the lower tooth parts of the two stator cores respectively.
