PISTON AND CYLINDER COMBINATION DRIVEN BY LINEAR MOTOR WITH PISTON POSITION RECOGNITION SYSTEM AND LINEAR MOTOR COMPRESSOR AND AN INDUCTIVE SENSOR

摘要

the present invention the support structure 4 and which forms an air gap 12 ; At least an air gap of the motor winding for generating a variable magnetic flux along the portion of the 12 (6); Cylinder (2) having a head on one of the end; The magnet is driven by the magnetic flow of the motor winding (6) to move the air gap 12 in the displacement path inside comprises at least in part, a displacement of the magnet is a reciprocally inside the piston (1) of the cylinder (2) go to make, a magnet (5) associated with the piston (1); Displacement of the piston (1) to generate a voltage signal arising from reaches at least a pre-selected position, the inductive sensor detects a change in magnetic field resulting from the corresponding position of the magnet, the magnetic field changes, the magnet (5) It discloses a piston and cylinder combination driven by linear motor and having a piston equipped with a positioning system comprising inductive sensor (8) disposed in the path point. The invention also includes a type of piston and cylinder combination of the present invention discloses a linear motor compressor that can recognize the position of the cylinder. ;
