Abstract

New devices of magnetic couplings, angled and non-angled, with their uses, are presented.

Claims

1-19. -19. (canceled)

20. A magnetic coupling for use with turbines, comprising:

a. A magnet set on each couple at a matching angle between 1 and 89 degrees to the plane perpendicular to the shaft.

21. The coupling of claim 20, wherein at least one of the magnet sets comprises electromagnets.

22. The coupling of claim 20, wherein the angle is 10 degrees, plus or minus less than 5 degrees.

23. The coupling of claim 22, for use with a pump.

24. The coupling of claim 20, for use with an underwater impeller turbine.

25. The coupling of claim 20, wherein at least one magnet set is arranged in a radial distribution, and wherein at least two magnets are substantially adjacent and of alternating polarity facing the other couple.

26. The coupling of claim 25, further comprising a matching electromagnetic couple.

27. The coupling of claim 25, wherein the magnet set is angled between 1 and 89 degrees.

28. A magnetic coupling, wherein at least one of the magnets is in a circumferential distribution.

29. The coupling of claim 28, further comprising at least one radially oriented magnet.

30. The coupling of claim 28, wherein at least one of the couples comprises electromagnets.

31. A magnetic coupling, comprising at least one radially aligned magnet, wherein the ratio of the average length (from the outer periphery of the magnet to the inner periphery) to average thickness (that is, the side of the magnet perpendicular to its direction of attachment to the other coupling) has a ratio of average length to average width of at least 5 to 1.

32. The coupling of claim 31, with a ratio of at least 10 to 1.

33. The coupling of claim 31, wherein the magnet set is angled between 1 and 89 degrees.

34. A magnetic coupling, associated with a rotating shaft, comprising an anti-collapsing means between the two sides of the coupling.
