Electromagnetically actuated brake

Image Number 3 for United States Patent #6269917.

For an electromagnetically actuated brake, in particular a stopping brake, having a high stopping moment and short braking paths and consisting of a cam disc (3) which is guided in a torsion-proof manner, a spring (4) which presses the cam disc axially into the locking position, and an electromagnet (5, 6, 7) which unlocks the cam disc against the spring (4), it is proposed that the axially movable cam disc (3) be of ferromagnetic construction and that a number of cams (31) be provided which engage, in a form-locking manner, in the recesses (11) in the rotatable part (1) to be braked, the cams (31) and recesses having flanks standing perpendicularly to the direction of rotation and the spring being constructed as a leaf spring (4) with three bending arms which act upon the face of the cam disc (3) at an equal distance from one another.
