  • Patent number: 6054788
    Abstract: A magnetic coupling is provided having a first shaft and a second shaft. A plurality of first magnets is in rotationally driving engagement with the first shaft and defines alternating polarity magnetic surfaces. A plurality of second magnets is in rotationally driving engagement with the second shaft and defines alternating polarity magnetic surfaces. The first and second magnet surfaces are separated by a gap so that rotation of one of the first magnets and second magnets urges synchronous rotation of the other. An electrically conductive member is in rotationally driving engagement with the second shaft and is disposed proximate to the first magnet surfaces so that rotation of the conductive member or the first magnets relative to the other induces electric current in the conductive member and urges asynchronous rotation of the other of the conductive member and the first magnets in the same rotational direction.
