Abstract
The invention discloses a double-cylinder linear compressor. Rotators of the double-cylinder linear compressor are in cylinder shapes; distance is formed between two stators axially; two pairs of permanent magnets are axially arranged. Radial alternating magnetic fields with different polarities are generated through the two stators when winding coils are electrified with alternating currents and the stator magnetic fields and rotator permanent magnetic fields are interacted, so that the stators perform reciprocating motion along an axial suspension state. Purposes of buffering, positioning and controlling strokes of the rotators are effectively achieved meanwhile the stator magnetic fields generate the suction and the pushing force to the permanent magnetic fields. The double-cylinder linear compressor has the advantages of being simple and compact in structure, low in cost, light in weight and convenient to machine due to the facts that a positioning spring is saved and positioning is performed through electromagnetic fields.
