Problems solved by technology

It can be seen that the mover 92 of the conventional electro-pneumatic cylinder 9 is not easy to be attracted between the first stator 93 and the second stator 94, thereby reducing the smoothness of the mover 92 being attracted and reciprocating.

Abstract

A linear motor and a compressor are provided. The linear motor comprises a housing base, a rotor movably disposed in the housing base, and a stator unit surrounding the rotor. The rotor includes a shaft lever and a plurality of first magnetic poles and second magnetic poles disposed on the shaft lever. Each first magnetic pole has a first overlapping portion and a first extending portion. Each second magnetic pole has a second overlapping portion located between two adjacent first overlapping portions and a second extending portion. Through the structure design innovation, the distance from the stator unit to the first and second magnetic poles is shortened, and the smoothness that the stator unit generates a magnetic force to drive the rotor to move can be actually improved.

Description

technical field [0001] The invention relates to a motor and a compressor, in particular to a reciprocating linear motor and a compressor. Background technique [0002] Machinery is the mother of industry, and the compressor itself is not only an important part of the overall manufacturing industry, but also the rock of the overall manufacturing industry. Among them, according to the compression method, the compressor can be divided into volumetric type and dynamic type. Volumetric type is specifically such as reciprocating type, rotary type, scroll type or spiral type, and dynamic type is such as centrifugal type. [0003] It is worth mentioning that the reciprocating linear compressor has the characteristics of high efficiency, compact structure, and small volume. In addition, the direction of its electromagnetic driving force is always on the same line as the direction of piston movement, and there will be no radial force on the piston. Or the radial force is very small, ...
