specific Embodiment approach

[0022] The specific embodiment: the present invention will be further described below in conjunction with accompanying drawing:

[0023] Such as figure 1 As shown, a direct-drive direct magnetic levitation linear compressor mainly includes a cylinder 1, a piston 2, a stator and a mover, the stator is composed of an excitation winding 10, a pole core 11 and a stator yoke 12, and the mover is composed of a motor Composed of mover core 6 and armature winding 7;

[0024] The piston 2 is set in the cylinder 1 and reciprocates in the cylinder 1 when in use, the piston 2 is connected with the piston rod 3, the piston rod 3 is connected with the motor mover core 6, and the armature winding for generating electromagnetic thrust is arranged in the motor mover core 6 7. During use, the motor mover core 6 and the motor pole core 11 move relatively, and the magnetic pole core 11 is provided with an excitation winding 10 .

[0025] The electric rotor core 6 is in a magnetic levitation sta...

Abstract

A direct-drive direct magnetic levitation linear compressor, the compressor mainly includes a cylinder, a piston, a stator and a mover, the stator is composed of an excitation winding, a magnetic pole core and a stator yoke, and the mover is composed of a motor mover core and an armature winding ;It uses the magnetic field generated by the excitation winding and the magnetic pull generated between the mover core to suspend the mover core to eliminate the friction of the motor itself, which will further prolong the life of the compressor and reduce wear, improve the efficiency of the compressor, reduce noise and save energy. is of great significance.

Description

technical field [0001] The invention relates to a compressor, in particular to a direct-drive direct magnetic levitation linear compressor for refrigeration equipment, belonging to the field of refrigeration equipment. Background technique [0002] The piston reciprocating compressor is composed of a cylinder, a piston, a crank, a connecting rod, an intake valve, an exhaust valve and a rotating motor. Due to the friction loss and rotational friction loss caused by the centrifugal inertia force caused by the unbalanced rotation of the crank in the crank-connecting rod transmission mechanism, the efficiency of the compressor is reduced, the volume and noise are increased, and the service life is reduced, and because it is difficult to achieve oil-free lubrication , so that harmless refrigeration is limited, so it is necessary to develop a new type of high-efficiency refrigeration compressor. [0003] Direct-drive direct magnetic levitation linear compressor, because there is ...
