Abstract:
An eddy current brake comprising:a diamagnetic or non-magnetic member; a first support wall; a separate second support wall disposed in a spaced apart relationship with said first support wall for enabling the member to pass therebetween; a first linear array of permanent magnets disposed on the first wall on a side of the first wall facing the second wall; a second linear array of permanent magnets disposed on the second wall on a side of the second wall facing the first wall, the first and second arrays being parallel with one another; and apparatus for adjusting eddy current induced in the member, and braking force, as a function of velocity of the member between the arrays, said apparatus including linkages for enabling movement of the member therepast to change the spaced apart relationship between the first and second walls.
