Abstract

A linear motor structure includes a stator, at least one moving member, and at least one linear member. The stator extends along an axial direction and has an electromagnetic acting surface. The moving member has an elongated hollow portion passing through the moving member and having a closed annular shape. The stator passes through the elongated hollow portion in the axial direction and is encircled by the moving member. The moving member has an electromagnetic portion relative to the electromagnetic acting surface of the stator. The moving member is electromagnetically reciprocated along the axial direction. The linear member extends along the axial direction. The moving member is coupled to the linear member. Because the moving member is closed and annular, the electromagnetic portionhas sufficient supporting rigidity and won't be deformed by the electromagnetic action. When the electromagnetic part of the moving member is a magnet, magnets can be combined with the two opposite sides of the electromagnetic acting surface of the stator, so that the density of magnetic lines of force is increased, and the thrust of the linear motor is improved.

Description

technical field [0001] The invention relates to a linear motor structure, in particular to a linear motor configured as a closed ring-shaped elongated hollow part on which the stator penetrates and extends the mover. Magnetic parts are arranged on the opposite sides of the stator to increase the magnetic line density to increase the thrust of the linear motor. At the same time, due to the closed feature of the mover, when the magnetic line density increases, the rigidity of the mover is increased to avoid deformation. Background technique [0002] Traditional linear motors are shown in Taiwan Patent No. I647895 "Linear Motor, Stage Device". The linear motor is composed of a stator and a mover. reciprocating motion along the stator. Since the two are operated by means of electromagnetic action, the mover and the stator must be close and adjacent. At this time, if a sufficiently large thrust is required to increase the number of magnetic parts to increase the magnetic force l...
