Abstract
Eddy current braking apparatus includes a linear array of spaced apart permanent magnets arranged for defining a slot therebetween. A diamagnetic or non-magnetic fin is disposed and sized for movement through the slot. A pivotal linkage enables the magnets to move with respect to the fin from a spaced apart first position to a second position in which the fin passes through the slot. A control mechanism selectively moves the magnets between the first and second positions.
Claims8
Eddy current braking apparatus comprising:
- a linear array of spaced apart permanent magnets attached to a stationary surface;
- a diamagnetic or non-magnetic moveable fin;
- control means for selectively causing the magnets and member to pass one another at a distance sufficient to cause eddy current to be introduced in the member, resulting in a braking force between the magnets and the member, said control means includes means for moving the magnets in a direction generally perpendicular to the moveable fin, the means for moving the magnets including a pivotal linkage interconnecting the magnets and the stationary surface, the moveable fin being disposed between said stationary surface and the magnets and the control means including a line disposed around a set of pulleys, for moving the magnets adjacent the fin upon tension being applied to the line.
Eddy current braking apparatus comprising:
- a linear array of spaced apart permanent magnets arranged to define a slot therebetween;
- a diamagnetic or non-magnetic fin disposed and sized for movement through said slot;
- a linkage pivotally mounting the magnets to a stationary surface, for enabling the magnets to move from a spaced apart first position with respect to the fin to a second position in which the fin passes through the slot;
- and
- control means for selectively moving the magnets between the first position and the second position, said control means including a line, disposed around a set of pulleys for enabling tension applied to said line to move the magnets from the first position to the second position.
In an eddy current braking system including a linear array of permanent magnets and a diamagnetic or non-magnetic fin mounted for passage past one another, an improvement comprising:
- a pivotal linkage interconnecting the magnets and a stationary surface, the fin being disposed between said stationary surface and the magnets;
- a set of pulleys;
- and
- a line disposed around said set of pulleys for moving the magnets toward the fin upon tension being applied to said line.
