Switchable permanent magnet brake
摘要:
A switchable permanent magnet eddy current or track brake which has a high density of permanent magnet material, a low internal flux leakage and a higher than heretofore output flux density. The pole shoes of the movable magnets are convex cylindrical segment-shaped and mate with concave cylindrical segment-shaped recesses in the lateral flux return pieces for the fixed magnets.
