Embodiment Construction

[0019] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

[0020] In order to better understand the illustrative embodiments of the present invention, a brief description of the main idea of ​​the present invention follows.

[0021] Such as figure 1 As shown, in the current motor structure of the linear compressor, the magnet 10 is interposed between the inner stator 3 and the outer stator 2 . When the motor is energized, the magnet 10 receives force and moves between the inner stator 3 and the outer stator 2 . There are two extreme positions in the movement of the magnet 10, which are respec...

Abstract

The invention discloses a motor structure of a linear compressor and the linear compressor. The motor structure comprises an inner stator, an outer stator and a mover, wherein the mover comprises a mover framework and a magnet; the inner stator is formed by two annular magnetic conductive sheet groups buckled on the two sides of a coil; the thicknesses and / or lengths of the outer walls, matched with the magnet, of the two annular magnetic conductive sheets are different. The problem of magnet stress decline caused by the reason that the magnet is not in a balanced position is solved by changing the width of the magnetic conductive sheets for forming the inner stator; in addition, a magnetic saturation phenomenon caused by an uneven contact area between the magnet and the inner stator also can be avoided; and therefore, the performance and the efficiency of the motor are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of refrigeration compressors, in particular to a motor structure of a linear compressor and the linear compressor. Background technique [0002] In the existing linear compressor structure, especially in the linear motor structure with coils wound on the inner stator, the inner stator is usually designed symmetrically. The reason is that when the motor is energized, in order to make the magnetic field generated by the current The flow between the stators is uniform, so that the mover receives a relatively uniform motor force, and the compressor runs stably. [0003] However, there are two situations in actual use, which make such a design less than ideal. One is that when the motor is energized and running, the coil generates an electromagnetic field, which interacts with the magnet on the mover to drive the magnet to move. The two extreme positions of the magnet movement are called dead centers, the top d...
