US 2002/0153782 A1 · Reciprocating motor

Abstract

A reciprocating motor for a reciprocating type compressor includes a bobbin having a coil wound inside thereof, a terminal formed at one side of the bobbin, for electrically connecting the coil and an external circuit, a core part at which a plurality of lamination sheets are radially stacked in a circumferential direction centering around the bobbin, and a fixing part for fixing at least one lamination sheet at the inner side of the core part. With this construction, the lamination sheets making the core part is prevented from vibrating and the collision between the lamination sheets and the terminal is prevented, so that when the motor operates, its noise is reduced and reliability of the operation of the motor is heightened.
