Abstract
A magnetic field positioning linear compressor is cylindrical and is axially provided with two pairs of tile-shaped permanent magnets and two stators. Space is reserved between stator cores. When two ends of one pair of tile-shaped permanent magnets are aligned with two ends of the stator cores, the end of the outer side of the other pair of tile-shaped permanent magnets is aligned with the central positions of the stator cores. Active cell permanent magnets are opposite. When a ring winding coil is electrified with alternating current, the two stators generate two pairs of radial alternating magnetic fields different in polarity, and the stator magnetic fields and the active cell permanent magnets interact to enable active cells to perform linear reciprocating motion in a suspension state along the axial direction. The goal of buffering, positioning and controlling stroke of the stators can be effectively achieved while the stator magnetic fields generate suction and thrust to the two active cells. The magnetic field positioning linear compressor is simple in structure, low in cost, light in weight, high in efficiency and convenient to process and manufacture.
