Abstract
(EN)
The present invention relates to a linear motor and a linear compressor. A linear motor according to an idea of the present invention comprises: a first stator; a second stator disposed inside the first stator; and a mover disposed between the first stator and the second stator so as to be movable in an axial direction. The mover includes: a plurality of permanent magnets; a front sub core disposed at the front of the plurality of permanent magnets in the axial direction; and a rear sub core spaced from the front sub core in the axial direction so as to be disposed at the rear of the plurality of permanent magnets in the axial direction, wherein the front sub core and the rear sub core are formed to have the same shape.

La présente invention se rapporte à un moteur linéaire et un compresseur linéaire. Un moteur linéaire selon une idée de la présente invention comprend: un premier stator; un second stator disposé à l'intérieur du premier stator; et un dispositif de déplacement disposé entre le premier stator et le second stator de façon à être mobile dans une direction axiale. Le dispositif de déplacement comprend: une pluralité d'aimants permanents; un sous-noyau avant disposé à l'avant de la pluralité d'aimants permanents dans la direction axiale; et un sous-noyau arrière espacé du sous-noyau avant dans la direction axiale de façon à être disposé à l'arrière de la pluralité d'aimants permanents dans la direction axiale, le sous-noyau avant et le sous-noyau arrière étant formés pour avoir la même forme.
