Cooling system for linear motors
View Patent ↗The present application is directed to a linear motor and includes a first mounting plate having an interior face disposing one or more magnetic elements thereon, a second mounting plate having an interior face disposing one or more magnetic elements thereon, a cooling element positioned between the interior faces of the first and second mounting plates and defining one or more cooling passages therein, the cooling passages having one or more heat sink wall members therein, at least one end cap configured to be coupled to cooling element and enclose the cooling passages therein, at least one seal positionable between the end cap and the cooling element and configured to couple the end cap to the cooling element in sealed relation, and a forcer device positioned between the magnetic elements on the first and second mounting plates and configured to movably engage the cooling element.
1. A linear motor, comprising:
a first mounting plate having an interior face disposing one or more magnetic elements thereon;
a second mounting plate having an interior face disposing one or more magnetic elements thereon;
a cooling element positioned between the interior faces of the first and second mounting plates and defining one or more cooling passages therein, the cooling passages having one or more heat sink wall members therein;
at least one end cap configured to be coupled to the cooling element and enclose the cooling passages therein;
at least one seal member positionable between the end cap and the cooling element and configured to couple the end cap to the cooling element in sealed relation; and
a forcer device positioned between the magnetic elements on the first and second mounting plates and configured to movably engage the cooling element.
2. The device of claim 1 wherein the first and second mounting plates and manufactured from the same material.
3. The device of claim 1 wherein the first and second mounting plates and manufactured different materials.
4. The device of claim 1 wherein at least one of the first and second mounting plates are manufactured from at least one material selected from the group consisting of steel, aluminum, titanium, brass, ferromagnetic materials, copper, metallic alloys; various plastics, vinyl, polyester, polystyrene, and polycarbonate, ceramic materials, elastomers; fiberglass, composite materials, and glass impregnated materials, and glass-reinforced materials.
5. The device of claim 1 wherein the magnetic elements positioned on the first mounting plate and the magnetic elements on the second mounting plate are manufactured from the same material.
6. The device of claim 1 wherein the magnetic elements positioned on the first mounting plate and the magnetic elements on the second mounting plate are manufactured from different materials.
7. The device of claim 1 wherein the cooling element further includes at least one canal formed thereon, the forcer configured to engage the canal in movable relation.
8. The device of claim 7 further comprising at least one bearing system positioned within the canal.
9. The device of claim 1 wherein the heat sink wall members are configured to increase the surface area of the cooling passages thereby improving the thermal transfer characteristics of the cooling elements.
10. The device of claim 1 further comprising at least one fastener configured to couple the first and second mounting plates to the cooling element.
11. The device of claim 1 wherein the cooling element comprises multiple cooling passages formed within the cooling element.
12. The device of claim 1 wherein the end cap devices includes at least one port formed therein, the port in fluid communication with at least one cooling passage formed in the cooling element.
13. The device of claim 1 wherein at least one of the first and second mounting plates includes an insulating material therein.
14. The device of claim 13 wherein the insulating material is an electrical insulating material.
15. The device of claim 13 wherein the insulating material is an thermal insulating material.
16. The device of claim 1 wherein the forcer device includes at least one bearing system thereon.
17. A linear motor, comprising:
a first mounting plate having an interior face disposing one or more magnetic elements thereon;
a second mounting plate having an interior face disposing one or more magnetic elements thereon;
a cooling element positioned between the interior faces of the first and second mounting plates and defining one or more cooling passages therein, the cooling passages having one or more heat sink wall members therein;
at least one end cap configured to be coupled to the cooling element and enclose the cooling passages therein, the end cap having one or more ports formed thereon, the one or more ports in fluid communication with the cooling passages formed within the cooling element;
at least one seal positionable between the end cap and the cooling element and configured to couple the end cap to the cooling element in sealed relation; and
a forcer device positioned between the magnetic elements on the first and second mounting plates and configured to movably engage the cooling element.
18. The device of claim 17 wherein the cooling element further includes at least one canal formed thereon, the canal having a bearing system configured to engage the forcer device in movable relation.
