Abstract
The utility model discloses a cylindrical-shaped magnetic field positioning linear compressor, which is axially provided with two pairs of tile-shaped permanent magnets and two stators. Stator iron cores are disposed at an interval in an axial direction, when the two end parts of a pair of tile-shaped permanent magnets are aligned with the two end parts of the stator iron cores, the end parts of the outer sides of the other pair of tile-shaped permanent magnets are aligned with the middle positions of the stator iron cores. The rotor permanent magnets are anisotropic. When alternating current is provided for an annular-shaped winding coil, the two stators can generate two radial alternating magnetic fields having different polarities. The stator magnetic fields and the rotor permanent magnetic fields can interact with each other, and therefore the rotors can carry out the straight reciprocating motion under the suspension state along the axial direction. The attraction force and the thrust force of the two rotors can be generated by the stator magnetic fields, and at the same time, the objects of buffering, positioning, and controlling the routes of the rotors can be effectively achieved. The magnetic field positioning linear compressor has advantages of simple structure, low costs, light weight, high efficiency, and convenient processing and manufacturing.
