Abstract

The present invention provides a secondary side of a linear motor, which mainly includes a base, a combining mechanism and multiple magnetic members, wherein the base has multiple plates that are sequentially stacked into a block; the combining mechanism is configured to combine the plate-shaped bodies; and the magnetic members are disposed on the base in a separated manner.

First claim

What is claimed is:

1. A secondary side of a linear motor, comprising:
a base, having multiple plates that are plate-shaped bodies sequentially stacked into a block;
a combining mechanism, for combining the plate-shaped bodies; and
multiple magnetic members, disposed on the base separately;
wherein the plates are sequentially stacked in a Z-axis direction, the Z-axis direction being perpendicular to an X-axis direction in which a linear motor formed by the secondary side of the linear motor provides a thrust and being in the same vertical plane with the X-axis direction;
wherein the combining mechanism has multiple rivet protrusions respectively protruding from the plates and extending to be combined with adjacent plate-shaped bodies of the plate-shaped bodies, and the rivet protrusions are respectively located between adjacent magnetic members of the multiple magnet members.

2. The secondary side of the linear motor according to claim 1 , wherein at least a part of each plate is made of magnetically conductive or non-magnetically conductive materials.

3. The secondary side of the linear motor according to claim 1 , wherein the combining mechanism has multiple rivets respectively penetrating through the stacked plate-shaped bodies, and the rivets are respectively located between the adjacent magnetic members.

4. The secondary side of the linear motor according to claim 1 , wherein the combining mechanism has an adhesive applied between the plate-shaped bodies.

5. The secondary side of the linear motor according to claim 1 , wherein the combining mechanism has at least one weld bead formed on one side of the base by welding.

6. The secondary side of the linear motor according to claim 1 , wherein the base further comprises a thermal insulating layer located on a side surface of the block formed by stacking the plate-shaped bodies.
