Abstract
The invention discloses a double-stator linear compressor. The double-stator linear compressor is characterized in that a rotor support and a stator support are cylindrical, two stators and two pairs of shoe-shaped permanent magnets are axially arranged in the stator support at intervals, and one pair of shoe-shaped permanent magnets is aligned with the center of a stator core when two ends of the other pair of shoe-shaped permanent magnets are aligned with two ends of another stator core. Rotor permanent magnets have reverse polarities. When alternating current flows into an annular winding coil, two radial alternating magnetic fields with different polarities can be generated by the two stators, and the stator magnetic fields and rotor permanent magnetic fields interact with one another, so that a rotor can linearly reciprocate in an axial suspension manner. The stator magnetic fields exert attractive force and thrust on two rotor permanent magnets while purposes of buffering and controlling strokes of the rotor and positioning the rotor can be effectively achieved. The double-stator linear compressor has the advantages of simple structure, low cost, light weight, high efficiency and convenience in machining and manufacturing.
