Abstract

The invention relates to an arrangement for the non-contact defined movement of at least one magnetic body, free to move in at least one dimension. A simple arrangement of this type, taking up a reduced volume, of universal application, for both positioning and orientation and also for energy generation and transmission, can be achieved, by means of arranging the body with a magnetic moment in the primary magnetic field of at least one permanent magnet which moves in a defined manner, said body having a secondary magnetic field extending from the body, aligned with the primary magnetic field. At least one magnetic field sensor is provided to record the secondary magnetic field in any position of the body.

Claims

1-16. -16. (canceled)

17. Apparatus for effecting non-contact defined movement of at least one magnetic body, comprising a body having a magnetic moment, at least one permanent magnet and at least one magnetic field sensor, wherein the body is arranged free to move in at least one dimension in a primary magnetic field of the at least one permanent magnet, the permanent magnet has a secondary magnetic field extending from the body and aligned with the primary magnetic field and the at least one magnetic field sensor registers the secondary magnetic field in any position of the body.

18. Apparatus according to claim 17, further comprising a capsule and wherein the body is a spherical dipole three-dimensionally supported in the capsule.

19. Apparatus according to claim 17, further comprising a liquid in which the body floats.

20. Apparatus according to claim 19, wherein the secondary magnetic field exhibits a lagged phase position relative to the primary magnetic field which reflects the viscosity of the liquid.

21. Apparatus according to claim 17, wherein the permanent magnet is rotationally symmetric about an axis of symmetry, is radially magnetized and is supported for pivoting about said axis.

22. Apparatus according to claim 17, wherein the magnetic field sensor acts in three dimensions.

23. Apparatus according to claim 17, further comprising a compensation system for the magnetic field sensor, wherein the compensation system compensates the primary magnetic field at the magnetic field sensor.

24. Apparatus according to claim 21, wherein the compensation system comprises a magnet fixedly connected to the permanent magnet and supported for pivoting about said axis and at the magnetic field sensor the compensation system generates a field of the same strength as and directed opposite to the primary magnetic field.

25. Apparatus according to claim 17, further comprising at least one other magnetic body and wherein said secondary magnetic field acts as a primary magnetic field for exciting the at least one other magnetic body.

26. Apparatus according to claim 22, wherein the magnetic field sensor is a magnetometer.

27. Apparatus according to claim 18, further comprising a three-dimensionally acting coil system fixed to the capsule.

28. Apparatus according to claim 27, further comprising an evaluation and control unit and wherein movement of the body in the capsule generates currents in the coil system which are transmitted to the evaluation and control unit for determining the spatial location and orientation of the capsule.

29. Apparatus according to claim 27, wherein the coil system and the body comprise a generator for producing energy and the apparatus further comprises means for transmitting the energy for storage or consumption.

30. Apparatus according to claim 29, further comprising means for switching coils of the coil system in series.

31. Apparatus according to claim 29, wherein the body rotates about an axis and the apparatus further comprises a casing and a transmission capsule, the transmission capsule having a shaft which at least approximately aligns with the axis and the capsule and the transmission capsule are fixed on opposite sides of the casing.

32. Apparatus according to claim 28, wherein the evaluation and control unit is electronically connected to the coil system and generates an additional magnetic field via the coil system and the additional magnetic field interferes with the secondary magnetic field of the body as movement of the body occurs.
