Title:
MOVABLE CORE TYPE RECIPROCATING MOTOR AND RECIPROCATING COMPRESSOR HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2018/131859
Kind Code:
A1
Abstract:
A movable core type reciprocating motor and a reciprocating compressor having the same according to the present invention comprise: a stator including an inner stator and an outer stator which is arranged on the outside in the radial direction of the inner stator to be spaced apart therefrom such that one side of the outer stator is connected to one side of the inner stator, and the other side of the outer stator forms a gap with the other side of the inner stator; a magnetic coil wound between the inner stator and the outer stator; a magnet fixed to at least one of the inner stator or the outer stator so as to be exposed to the gap; a movable core, disposed in the gap and made of a magnetic material, for reciprocating with respect to the stator and the magnet; and a mover including a hollow connecting member, made of a non-magnetic material, for supporting the movable core such that the movable core is exposed to the gap toward the magnet, whereby the reciprocating motor and the reciprocating compressor having the same are reduced in size and weight, and a higher efficiency can be obtained.
