Abstract

A transport device has a stator and at least one transport element. The transport device is designed to transport the transport element in a controlled manner relative to the stator, and the stator or the transport element has multiple movable actuating magnets, each of which is connected to the stator or transport element via an actuating element. The actuating element is designed to change the position and/or orientation of the connected actuating magnet relative to the stator or transport element in a controlled manner. The respective other part has at least two stationary magnets fixedly connected to the respective other part. The stator and the transport element are magnetically coupled by means of the stationary magnets and actuating magnets, and the transport device is designed to transport the transport element relative to the stator by the control positioning and/or orientation of the actuating magnets by means of the actuating magnets.

Dependent claims

A conveying device comprising:

a stator;
and
at least one transport body, the conveying device configured to convey the at least one transport body relative to the stator in a controlled manner, wherein:
one of the stator and the at least one transport body comprises multiple movably arranged actuating magnets, each actuating magnet connected by an actuating element to the one of the stator and the at least one transport body, wherein the actuating element is configured to vary a position and/or an orientation of the actuating magnet connected thereto relative to the one of the stator and the at least one transport body in a controlled manner,
the other of the stator and the at least one transport body comprises at least two static magnets connected to the other of the stator and the at least one transport body such that the at least two static magnets are immovable relative to the other of the stator and the at least one transport body,
the stator and the at least one transport body are magnetically coupled by the at least two static magnets and the multiple actuating magnets,
the controlled position and/or orientation of the actuating magnets via the actuating elements is used to levitate and stabilize the at least one transport body with respect to the stator, and to propel the at least one transport body in different directions with respect to the stator depending on the controlled position and/or orientation of the actuating magnets,
the stator includes a conveying surface, and
the actuating elements are configured to rotate the actuating magnets about axes that are perpendicular to the conveying surface.

A method for operating a conveying device that comprises a stator and at least one transport body, wherein one of the stator and the at least one transport body comprises multiple movably arranged actuating magnets, each actuating magnet connected by an actuating element to the one of the stator and the at least one transport body, wherein the actuating element is configured to vary a position and/or an orientation of the actuating magnet connected thereto relative to the one of the stator and the at least one transport body in a controlled manner, wherein the other of the stator and the at least one transport body comprises at least two static magnets connected to the other of the stator and the at least one transport body such that the at least two static magnets are immovable relative to the other of the stator and the at least one transport body, wherein the stator and the at least one transport body are magnetically coupled by the at least two static magnets and the multiple actuating magnets, and the conveying device is configured to convey the at least one transport body relative to the stator by at least one of controlled positioning and controlled orientation of the multiple actuating magnets via the actuating elements, the method comprising:

activating the actuating elements by at least one of controlled positioning and controlled orientation of the multiple actuating magnets via the actuating elements to levitate and stabilize the at least one transport body with respect to the stator;
and
activating the actuating elements to position and or orient the multiple actuating magnets to propel the at least one transport body in at least one direction with respect to the stator,
wherein the stator includes a conveying surface, and
wherein the actuating elements are configured to rotate the actuating magnets about axes that are perpendicular to the conveying surface.
