Abstract

A movement device comprising a first and a second assembly, the first assembly being composed of a plurality of subassemblies. Two directly adjacent subassemblies are conterminous with each other at a boundary line. The two subassemblies form at least one first pair of directly adjacent first permanent-magnet arrangements that are separated from each other by the boundary line. The two first permanent-magnet arrangements of the first pair are each arranged with a boundary distance from the boundary line that is reduced with respect to a spacing distance, such that they mutually have the spacing distance. There are present in each case within the said two subassemblies at least one second pair of directly adjacent first permanent-magnet arrangements that mutually have the spacing distance.

First claim

What is claimed is:

1. A movement device, comprising:
a first and a second assembly, the first assembly comprising a first base and a plurality of first permanent-magnet arrangements, the first permanent-magnet arrangements being connected to the first base, via a respectively assigned actuator, in such a manner that they are each movable as a whole in at least one degree of freedom, by the assigned actuator, relative to the first base, the second assembly comprising a second base and a second permanent-magnet arrangement, the second permanent-magnet arrangement being arranged in a fixed manner relative to the second base, the first assembly being composed of a plurality of subassemblies, which each form an assigned part of the first base, and they each comprise a plurality of first permanent-magnet arrangements having the respectively assigned actuator, wherein:
two directly adjacent subassemblies are conterminous with each other at a boundary line, the said two subassemblies forming at least one first pair of directly adjacent first permanent-magnet arrangements that are separated from each other by the boundary line, the two first permanent-magnet arrangements of the first pair each being arranged with a boundary distance from the boundary line that is reduced with respect to a spacing distance, such that they mutually have the spacing distance, there being present in each case within the said two subassemblies at least one second pair of directly adjacent first permanent-magnet arrangements that mutually have the spacing distance.

2. The movement device according to claim 1 , wherein
the subassemblies together form a gap-free movement surface of the first base that faces toward the second assembly.

3. The movement device according to claim 1 , wherein:
the actuators each have a single endless rotational degree of freedom, which defines a rotational axis, the rotational axis in each case being aligned substantially perpendicularly in relation to a movement surface of the first base, such that it intersects the latter, the spacing distance being measured at the corresponding intersection points.

4. The movement device according to claim 1 , wherein:
the spacing distance of the first and second pair being measured along a common axis.

5. The movement device according to claim 4 , wherein:
there is a first axis and a second axis that intersect at an angle other than zero, at least one first and a plurality of second pairs of first permanent-magnet arrangements being assigned both to the first axis and to the second axis.

6. The movement device according to claim 1 , wherein:
the boundary distance is equal to half the spacing distance.

7. The movement device according to claim 1 , wherein:
there is assigned to each subassembly a separate subsidiary control device, to which the actuators of this subassembly are connected, the subsidiary control devices being connected, at least indirectly, for data exchange.

8. The movement device according to claim 7 , wherein:
at least one subsidiary control device is connected for data exchange only to the subsidiary control devices that are arranged in directly adjacently arranged subassemblies.

9. The movement device according to claim 7 , wherein:
all subsidiary control devices are connected to a common main control device for data exchange.

10. The movement device according to claim 1 , further comprising:
a position determination device, each subassembly comprising a part of this position determination device.

11. The movement device according to claim 1 , wherein
each subassembly is provided with a separate cooling device, a plurality of cooling devices, preferably all, being connected to a common coolant supply and/or to a common coolant discharge.

12. A method for operating a movement device, comprising:
basing data exchange between subsidiary control devices a constant timing, wherein:
a first and a second assembly, the first assembly comprising a first base and a plurality of first permanent-magnet arrangements, the first permanent-magnet arrangements being connected to the first base, via a respectively assigned actuator, in such a manner that they are each movable as a whole in at least one degree of freedom, by the assigned actuator, relative to the first base, the second assembly comprising a second base and a second permanent-magnet arrangement, the second permanent-magnet arrangement being arranged in a fixed manner relative to the second base, the first assembly being composed of a plurality of subassemblies, which each form an assigned part of the first base, and they each comprise a plurality of first permanent-magnet arrangements having the respectively assigned actuator,
two directly adjacent subassemblies are conterminous with each other at a boundary line, the said two subassemblies forming at least one first pair of directly adjacent first permanent-magnet arrangements that are separated from each other by the boundary line, the two first permanent-magnet arrangements of the first pair each being arranged with a boundary distance from the boundary line that is reduced with respect to a spacing distance, such that they mutually have the spacing distance, there being present in each case within the said two subassemblies at least one second pair of directly adjacent first permanent-magnet arrangements that mutually have the spacing distance, and
there is assigned to each subassembly a separate subsidiary control device, to which the actuators of this subassembly are connected, the subsidiary control devices being connected, at least indirectly, for data exchange.

13. A method for operating a movement device, comprising:
exchanging data between subassemblies in the course of position determination, wherein:
a first and a second assembly, the first assembly comprising a first base and a plurality of first permanent-magnet arrangements, the first permanent-magnet arrangements being connected to the first base, via a respectively assigned actuator, in such a manner that they are each movable as a whole in at least one degree of freedom, by the assigned actuator, relative to the first base, the second assembly comprising a second base and a second permanent-magnet arrangement, the second permanent-magnet arrangement being arranged in a fixed manner relative to the second base, the first assembly being composed of a plurality of subassemblies, which each form an assigned part of the first base, and they each comprise a plurality of first permanent-magnet arrangements having the respectively assigned actuator,
two directly adjacent subassemblies are conterminous with each other at a boundary line, the said two subassemblies forming at least one first pair of directly adjacent first permanent-magnet arrangements that are separated from each other by the boundary line, the two first permanent-magnet arrangements of the first pair each being arranged with a boundary distance from the boundary line that is reduced with respect to a spacing distance, such that they mutually have the spacing distance, there being present in each case within the said two subassemblies at least one second pair of directly adjacent first permanent-magnet arrangements that mutually have the spacing distance, and there is assigned to each subassembly a separate subsidiary control device, to which the actuators of this subassembly are connected, and
all subsidiary control devices are connected to a common main control device for data exchange.
