Abstract

1. Switchable permanent magnetic brake, having pole pieces (1, 11) of alternating polarity adjacent to stationary and rotatable permanent magnets (2, 12 and 3, 13), the stationary permanent magnets (2, 12) being located with one pole thereof at laterally oppositely situated surfaces of the pole pieces (1, 11) and with the other pole at flux return elements (4, 14) each of the rotatable permanent magnets (3, 13) being magnetized transverse to an axis of rotation thereof which is located essentially perpendicular to a braking surface, substantially segment-shaped pole shoes (5, 15) provided at pole surfaces of the rotatable permanent magnets ; each of the pole pieces (1, 11) having substantially segment-shaped recesses located opposite the segment-shaped pole shoes (5, 15) and into which engage related ones of the segment-shaped pole shoes (5, 15), the permanent magnets (2, 12 and 3, 13), in the switched-on state of the brake, surrounding with the same polarity the related pole piece (1, 11) and neighboring pole shoes (5, 15), characterised in that the stationary and rotatable permanent magnets (2, 12 and 3, 13) protruding past surfaces (6, 16 and 7, 17) of the neighboring related pole pieces (1, 11) and pole shoes (5, 15) respectively.
