Abstract

A linear motor comprises an exciter that includes a plurality of permanent magnets in a shaft, an armature that surrounds the exciter and includes a plurality of coils, and a frame that houses the armature, wherein the armature houses the plurality of coils in a magnetic tube which has a linear opening.

Description

technical field [0001] The present invention relates to a linear motor that imparts a linear thrust to an object to be driven by electromagnetic induction. Background technique [0002] Since linear motors operate by electromagnetic induction, they are smaller and can operate at higher speeds than mechanical operations such as ball screw mechanisms. For example, a chip mounter (chip mounter, electronic component mounting device) of a semiconductor manufacturing device uses a rod-type linear motor. The rod-type linear motor includes a rod having a permanent magnet and a coil surrounding the rod, and the rod is given axial thrust to move linearly by electromagnetic induction of the magnetic field of the permanent magnet and the current flowing through the coil. [0003] As a related art of a rod-type linear motor, a linear motor in which a coil is inserted into an integral housing and resin-molded is disclosed (for example, refer to Patent Document 1). [0004] In addition, ...
