Problems solved by technology

In most cases, in order to make a positive contribution to the efficiency of the compressor motor, the number of stator windings needs to be increased, however the required safety clearance between the compressor body and the windings prevents the increase in the number of windings
In order to solve this problem, in the prior art, insulating elements made of isolating plastic films with a thickness of 0.15-0.20 mm are placed between the stator winding ends and the compressor body, however these insulating elements are placed in compression Several problems arise in electromechanical motors - especially labor issues caused by the shape of the winding heads and compressor body

Abstract

The present invention relates to a hermetic compressor (1) suitable for being used in cooling devices such as refrigerators comprising a casing (2), a stator (5) having a stator stack (3) composed of laminations and one or more than one winding (4) composed of conducting wires wound on the slots on the stator stack (3), more than one winding head (6) forming the portions of the windings (4) extending towards outside from the opposite faces of the stator stack (3), a compressor block (7) carrying basic mechanical elements such as cylinder, piston, crank and piston rod, seated on the upper surface of the stator stack (3) such that the lower surface thereof does not contact the winding head (6), a insulating jacket (11) produced from polyester film and providing insulation between the winding head (6) and the compressor block (7).

Description

technical field [0001] The present invention relates to a hermetic compressor including an insulating cover mounted to a compressor body. Background technique [0002] Stators for hermetic compressor motors used in cooling devices such as refrigerators are made by placing windings made of wire into slots on a stator lamination made of magnetic sheets, and passing the windings toward the outside through the The opposite sides of the stator laminations extend to form what are known as winding ends. Furthermore, a metallic compressor body placed on the stator is located in said compressor and carries the basic mechanical elements such as cylinders, pistons, crankshaft and piston rods. The compressor body is placed onto the stator laminations - above the winding ends. For safety reasons, so that there are no current jumps (leakage) between the winding wires and the body when current is applied to the stator winding, a minimum clearance of 2mm must be left between the compresso...
