Patent ID: 8368259

Claim:
A linear motor equipped with a field element and an armature, the linear motor adapted to produce a force causing the field element and the armature to be relatively displaced along a given axial direction by interaction of magnetic fluxes generated between the field element and the armature during an operation of supplying electric power to the armature, comprising: a stator formed as one of the field element and the armature; a mover formed as the other of the field element and the armature; a frame member defining the axial direction; a rail adapted to guide the mover allowing only to reciprocate in a linear direction; a first positioning portion provided on the frame member to set a fixing position of the stator with respect to the frame member; and a second positioning portion provided on the frame member to set a fixing position of the rail with respect to the frame member in such a manner as to allow the mover to reciprocate along the axial direction with a given gap formed between the mover and the stator positioned by the first positioning portion.
