Definitions

  • a maximum stroke range of the piston may be within a displacement at which the restoring force has an inflection point.
  • a reciprocating compressor including a stator provided with a stator core having at least one air gap and a coil generating magnetic energy, a mover provided with a magnet and reciprocating with respect to the stator, a cylinder having an accommodation space therein, and a piston coupled to the mover, forming a compression space along with the cylinder, and performing a resonant motion as the magnet receives a restoring force generated due to a difference of a magnetic level generated in the air gap of the stator core.
  • FIGS. 4 to 9 are conceptual views illustrating effects of an electromagnetic resonance spring according to a flowing direction of a flux in the compressor according to FIG. 2 .
  • FIG. 10 is a graph illustrating strength of a magnetic spring force for a position of a magnet.
  • FIG. 16 is a longitudinal sectional view illustrating an apparatus of assembling a magnet in a manner of being eccentric toward a compression space by using a magnetic force in a reciprocating compressor in accordance with the present invention.
  • the magnet 136 when the flux flows in a counterclockwise direction, namely, a direction B as illustrated in FIG. 6 , the magnet 136 generates a force attracting the stator 131 , 132 .
  • a force F 2 trying to pull the magnet 136 toward the stator 131 , 132 is applied to the magnet 136 by the attractive force.
  • the force F 2 proportionally increases as the magnet 136 is getting away from the stator 131 , 132 , and thus serves as a type of spring force. This is referred to as a magnetic spring force.
  • the magnetic spring force may not continuously increase as the magnet is getting away from the stator, but increase within an influence range of the magnetic flux and then be drastically lowered when exceeding the range. This has been described in relation to FIG. 10 .
