Efficient and energy-saving magnet-collecting direction-control linear motor for compression refrigeration

Abstract

The invention discloses an efficient and energy-saving magnet-collecting direction-control linear motor for compression refrigeration. The linear motor comprises an annular permanent magnet stator or a mover and an iron core coil mover or a stator; the linear motor is characterized in that N poles or S poles of permanent magnets for forming an annular magnetic field all face to interior of a ring to form inner ring homo-polar property so as to generate a strong annular inversion magnetic field with opposite ring opening magnetic field directions; the S poles or N poles of the permanent magnets for forming the annular magnetic field all face to exterior of the ring to form outer ring homo-polar property; and an iron core coil with certain length is placed in the inversion magnetic field ring. The efficient and energy-saving magnet-collecting direction-control linear motor has the advantages of simple structure, low production cost, energy-saving, electricity-saving, and high working efficiency; when a motor apparatus and a compression apparatus are directly combined into one body, a complex crank connecting rod structure can be omitted, intermediate consumption of electric energy can be reduced, and the operating efficiency of a mechanical system can be greatly improved by prolonging a piston travel of the inversion magnetic field, thereby enabling the piston pushing force to be higher.

Description

technical field [0001] The invention relates to a linear motor for compression refrigeration, in particular to a high-efficiency energy-saving magnetism-controlled linear motor for compression refrigeration. Background technique [0002] As we all know, the refrigeration compressor completes the gas compression and delivery process by changing the volume of the gas. Any power equipment needs a prime mover to complete the work, and the compressor is the same, it needs a rotary electric motor (motor) to drive. [0003] There are many types and forms of refrigeration compressors, among which positive displacement is the most common. Volumetric compressors are divided into two types: reciprocating piston type and rotary type. [0004] The reciprocating piston type is to change the working volume of the gas through the reciprocating movement of the piston in the cylinder. It has a long history of development and mature production technology. Rotary compressors include scraper ...
